Making Math Real: Percent, Discount, Sales Tax

One of the things I love about teaching math is that there is so much real-world application. Along with Science, it is one of the only subjects where, most of the time, I can make real-world connections with my students.

One of the things I hate about teaching math, is that the curriculum so infrequently reflects this real-world connection. (Sidenote: I recently stopped my lesson on probability with a 32 second mini-rant about how I have never in my entire life flipped a coin then spun a spinner and cared about the result. Honestly, come on curriculum peeps)

During our unit on percents I tried to remedy this lack of connection. I chose to take a lesson that involved 10 questions on discounts and sales tax and open a "mini-mall" in my classroom. I'm sure other teachers have done this much more effectively, but I had one day for this lesson (and I'm cheap and wasn't going to go out and buy a lot of items for my students to purchase like some much-more-awesome-than-me teachers do).

This is a great activity you can use for your students with minimal set up and high engagement.

Here's how it works:

1. Split your class into groups of 4. Each group will get one "Amount to Spend" card. I chose to use QR codes so students wouldn't be fighting over getting the larger amounts. 
2. Each student gets one "Discount" card. 

After that it is pretty much up to you how to run it. Here is what I did..

1. Students go a few at a time to the "mall" (a table in the back of the room where all the items to purchase are laid out) and choose one item. I made several copies of the items so there was enough for everyone and several of the popular items were still available. 
2. In groups, students calculate the amount of their item by find the discount and subtracting it. **An alternative is to have each member choose an item and then the group decides how to allocate their discounts. This gets them thinking a little more. 
3. Groups complete the recording sheet. If they have more money remaining after each member purchases something, they decide together what else to purchase and return to the "mall"
4. I announce that the mall is closing and if they want to make any final purchases, now is the time.
5. After closing, groups calculate the amount they spent. Then they calculate the sales tax for their items and answer the discussion questions. I had my students do their work on butcher paper on the desks, because that's fun. They could do whiteboards or notebooks, whatever floats your boat.

I love that this brings in real world topics like budgeting, over and under spending, sales tax (and why you have to pay it) and so many other skills that many of my students are unfamiliar with, while also teaching the skills of finding percent and discount. 

This activity was super easy to make, but if you don't want to reinvent the wheel, it is available at my shop on Teachers Pay Teachers shop. Click the button on the right sidebar or click here.

Tis the Testing Season

Tis the season.

State testing is upon us.

I teach in a large public school district in Texas which means the next few weeks will be filled with kitchy slogans somehow incorporating the word "STAAR." ("Shoot for the "STAARs!" "Be a STAAR!" and so on...)

With STAAR and other state tests fast approaching, teachers, administrators, and specialists are working and straining to find engaging (yet structured) ways to review an entire year's worth of material in 2 - 4 weeks. The problem is, there are many students who have mastered the material, and many who did not and need to be retaught pretty much everything.

There are oodles of ways to go about reviewing and many activities to trick students into practicing their material. Here is one method I've used successfully.

QR Code Scavenger Hunt:

Here's how it works. Each student needs a recording sheet and maybe a partner because that's always more fun. Cut out the cards lengthwise so that there is an answer and a QR code together, and post around the room. Students can start at any question. They scan the QR code on the right and answer the question, showing their work on their recording sheet. Once they have their answer, they look for the card with that answer on the left side. When they find it, they scan the QR code on that card to get their next question. If done correctly, students should see all questions and end up where they started.

The first time I did this I had low expectations, but I was surprised! Something about the magical QR code goodness sucks them in more than just your regular, old scavenger hunt. Try it. It's fabulous!

Mind the Gap: Student Paced Video Lessons

I teach 7th grade math at a junior high. At this school, we have two options for the "sevvies" as they join us from their cutesy elementary worlds: 7th Regular Math, 7th Pre AP math. Your higher-achieving students (or those with high achieving parents) opt for Pre AP and everyone else is slotted into regular. I don't mean this to say that those students in my regular classes aren't high-acheiving, quite the opposite for some. In a gentle way, some students who are in my class should be in Pre AP, but they may not have someone at home encouraging them to try for more or to challenge themselves, so they take regular math and it's a breeze for them.

I have other students who are, let's say, less than motivated; and who have been less-than-motivated for quite a while and are now drowning in the wide gaps in their math knowledge. Also throw in the mix students who work really hard and want to be successful, but just struggle with numbers. Next, add in a dash of  students who are new to the country and are just trying to keep their head above water as they are learning a new culture, language, education system and more. 

With all of that, I have a class with a wide range of ability, motivation, and knowledge and, as the Brits say, I need to mind the gap (I'm pretty sure that's meant in a very different context, but it sounds great in a British accent in my head, so I'm going with it). 

There is a wide gap between my high-achieving and my low achieving students. Between my native speakers and my language learners, between my motivated and my "ehs." I have one class in particular that is all over the place and I have been struggling with how to get a lesson to them...to ALL of them. 

So, I tried something that worked...pretty well. I used two pieces of tech for this to work: an app called ShowMe and QR codes.

If I am going to be out for a personal day or training, to make sure my kids get the lesson, and to make it easy on the sub, I will record the lesson using the Show Me app. I am cheap, so I use the free version of the app which is very limited in what it can do, but it gets the job done. Usually, I will take screen shots or pictures of the worksheet I am doing and will insert it in as a photo so I can model and write on it. Feel free to play around with it and I will work on a post with the ins and outs of Show Me because it has one feature I love. What I love about Show Me is that, when you make a video, you can host it through Show Me. That means, when you create a video, you get a link to that video you can send to others or, as I'll show in this post, attach to a QR code. Why is this great? With other programs, you will have to upload and host your video to another site, like YouTube. That's fine and dandy if you want your voice all out there on the internet, but not me, no way. And also, our school blocks YouTube which means the kids, the people who need the video the most, can't get to it. So, yeah, that won't work. 

First things first: Make your video. This day's lesson was learning to find the surface area of pyramids from nets. We had already learned how to find the surface area of prisms so it was kind of a review, or at the very least, most students could figure it out without a lot of extra instruction. So, I had 5 questions I wanted them to know how to solve, so I made 5 videos, one for each problem that showed me working them out and the steps to solve. Each video was 1:30 to 2 minutes long. After I made the videos, I emailed the link to myself and created a QR code for each link (if you don't know how to make a QR code, read here).

Choose your video from your dashboard on Show Me.
Click the arrow-box thing to share your Show Me video.
I usually email it so I have the link for QR codes or putting on class website.  

I then made a text QR code that when scanned would show the correct answer to the problem. 

Finally, I put it all together using Powerpoint (I wasn't making a presentation, I just find things are easier to manipulate on Powerpoint instead of Word). I included the text of the question, an image (if needed) and the two QR Codes, one for the answer, one for the video. 

I made one card for each question, each a half page and printed them out on color paper (because that's more fun...but certainly not necessary). I printed enough for students to work in partners. After introducing what we were going to do, I gave each pair a set of the 5 cards and an iPad (we only have enough iPads for pairs, at best). Students worked out the problem on their own worksheet instead of writing on the cards (ain't nobody got time to make sets for each class). 

When they got their answer they scanned the Answer QR code.

(Have you tried to screenshot before the reader grabs the code? Not easy)

What will appear after scanning "Video Help" QR Code

If they got it right, they moved on. If their answer was incorrect I asked them to compare their work with their partners, see if they made a calculation error and try and figure out what they did wrong (I like a little self-discovery in math). If they still couldn't figure out where they went wrong, they scanned the code and watched the short video of how to solve. 

Guys, this was amazing. 

The more advanced students paired together, solved the problems, then got to business on their homework. They weren't bored and shouting out as we slogged through at a pace that wasn't good for them. 

The shy students who are scared to ask for help had the help in their hands. I could literally help 15 groups of kids at one time through the videos. 

Students who knew most of the problems didn't have to hear their teacher prattle on about how to solve, instead they got help on exactly what they needed help on. 

And, an added perk is that I had to speak significantly less that day since my "lesson" was on the videos and could just be replayed. Instead, I walked around and corrected errors as I saw them and offered assistance exactly where it was needed instead of a blanket instruction to all. Students could work at their own pace and have their individual needs met, which I find is so hard to get done in a math classroom, especially one as diverse in ability levels as mine. 

I hope this was helpful. If you have tried other methods to solve this problem I would love to hear them! Until next time, happy tech-ing!

QR Codes + Google Forms = True Love

As the title says, love is in the air. QR Codes plus Google Forms, here to make your life a little easier.
I recently got certified as a "Google Level 2 Educator." I'm not entirely sure what the implications are of that title, but I learned a lot about Google programs, apps, extensions, and more. This is a trick I learned that will make some of the logistics of your day so much easier. Before I give you the steps, let me tell you how I use this:

1) Keeping a record (including time and date) of who comes to tutoring when and for what. This process gives me a constantly updated spreadsheet of who came to tutoring on what day and what they did and I don't have to do a thing to keep up with it!
2) Anytime a student is missing an assignment (typically homework) I keep a record of it for end-of-semester grade talks and potential retention meetings, or just your run-of-the-mill parent conference. This handy-dandy process gives you another spreadsheet of date, time, student name, and assignment missing and I don't have to do a thing to keep up with it!

**The one item that can be added on to this that makes it from awesome to super awesome-sauce, is a parent email that notifies the parent each time - whether it is that their child stayed for tutoring, or that their child is missing an assignment and, you guessed it...you don't have to do a thing to keep up with it! I'll follow up with that in my next post!


So here's what I'm talking about: a google form accessed by a QR code. A form that keeps track of parent communication, tutoring attendance, or missing assignments. Here's what you do:

1. Go to Google Forms and create a new form. Title the form "Missing Assignments" (or your choice)
2. Add questions with "Text" as the question type for each piece of information you want:

• Student Name
• Class
• Title of the Missing Assignment
• **Parent Email (they may not know their parents email, this could be an issue. Or, they try and type it in wrong. Even if they put in the wrong email purposely you still have documentation)
• For the email portion, click "Advanced Settings" and click "Data Validation" and "Email" 

**Only do this step if you want to send emails to let parents be notified. If an email is not necessary, you can skip this step. To see what to do to send out the emails, read my follow-up post here. 

3. Add an additional question with "Date" as the response type

For each "question" make sure you click "required question" When finished it will look like this:

To see what your form looks like, click "Live Form" on the tool bar. The page you see is what others see when they go to fill out your form.

Click to see what your form looks like to everyone else. 

     

What people see when they go to your form. 

When I create a new form, I like to do a "test" to make sure everything is working well. Go ahead and enter a few false entries on the form. After you type a few responses, go back to your Forms page. At the top toolbar you will see an icon that says "View Responses." This will take you to the spreadsheet that Forms creates to track the responses you receive from your form.

 My favorite feature is the time stamp. With so much documentation required in teaching, it's nice not to write the time and date. Thank you Google.

So, that's how you set up a form. The spreadsheet is created for you and saved in your Drive. To send the form to others you can use the blue "Send Form" icon at the top to email it. However, because QR codes are pairing up with Forms in this post, a more efficient way to use your form is to attach it to a QR code. That way multiple users can access the form without copying down a complicated URL. To do that, follow the steps below:

1) Click on "Send Form" and copy the link.
2) Use that link to create the QR Code
**If you don't know how to create a QR code, use my post here and follow the steps to create a QR code that links to a website.
3) Attach your code to whatever you are using it for. Below are two examples of posters I have in my room where the QR code links to a Google Form.

Used to keep track of who attends tutoring. Students scan with their phone when they come in and submit the form. No work required by me!

If a student comes to class without their homework they use their phone to scan the QR code and complete the form. That gives me a record of who does not have their homework each day (and keeps track of repeat offenders).

 So, there you go. QR Codes teaming up with Google Forms to make your life easier. I am doing a follow-up post (click here) that shows you how to take that spreadsheet and send a form email out from it each time a form response is recorded. This is how I let parents know, in real time,  that their student did not turn in their homework. Check back for that! Happy tech-ing!

How to Make a QR Code

By now you may have realized I like QR codes just a little. I love how easy they can make things. I use QR codes to link to forms, to engage students in an activity, to give a quick link to a video or website, and so much more. Because I love QR codes and use them so much, I take or granted the fact that not everyone knows how to make one or use them. I thought I would write a quick post about how I make a QR code to help you incorporate this lovely little tech tool into your classroom.

I'm sure there are a lot of different ways and websites to make QR codes, but I'll show you what I have used for the last few years that works very well (and free).

1. Go to www.qrstuff.com
2. Decide what you want your QR code to link to.
You can see from the list on the right that you can link to a website, YouTube video, all forms of social media, plain text, email address, and SO much more. The options that I use most frequently are website, YouTube Video, and Plain Text.
3. I'll show you how to link to an image. To link to an image, do a google search for your image online. When you find it, right click and copy the image address. 


4. Go back to qrstuff.com. Select website and copy the image into the address bar. The QR to the right of the screen will automatically change. You cannot right-click and copy the QR code, you must download and insert into your document from there.

And that's it! It's always a good idea to double check your QR code to make sure it links to what you want it to. The steps are the same for YouTube video and for text. For text, your screen would look like this (below) and your QR code, when scanned will show the image on the right.

                     

Hope this helps take away some of the uncertainty of how to make a QR code! Happy teching!

QR Codes - Activities

For the first few months on the math team at my new school I was known as the "QR code" girl.
I love QR codes.
Seriously.

They make so many activities and tasks in the classroom easier. A quick shortcut to a website, a link to a video, a cute picture at the end of an activity, and so much more!

Today I wanted to share a few ways I use QR codes in my math classroom, specifically with activities. I will write a post at a later date about how I use QR codes in other ways. Stay tuned!

After we teach a specific skill (area of polygons, solving equations, volume, etc) that just needs some practice and application, I begin to think in QR codes. I like to give my students a chance to practice the skill before we dive deeper into real-world application. I also like for them to be able to practice with a partner or small group and be able to check their own work because, honestly, I can't be bothered.

Here is how I use QR codes to help me:
1) I have 10-12 problems (or less, or more, up to you) that I want my students to solve and the corresponding answers.
2) I create a matching game in powerpoint (can use one of the editable docs I'll provide here).

3) I then generate a QR code with what I want the student to see if they get the answer right. I usually use well-known memes or characters I find in a quick google search. When I find the photo I want, I copy the image address and head on over to qrstuff.com to create my QR code. Here are some step-by-steps if you've never made a QR code:

1. go to www.qrstuff.com
2. "Data Type" - weburl
3. copy link for image into URL box
4. Click "Download Code" on the right (you can't copy and paste the code, you must download it)

I then put a code for a different image for each of the pairs of questions and answers. I split it between the two boxes on the table.

Cut the cards out along the lines in the table. This will split the QR code in two. When the kids begin the activity, they solve the problem, find the matching answer, line up the QR code and scan. If they don't have an image pop up their either have the wrong answer, or they just need to adjust the code so it is lined up correctly. 

My students LOVE this activity! I usually have them just turn in a list of the characters that came up when they scanned (I usually use Disney characters as most students recognize them). 

Another activity I have used is to create one large (8.5 x 11) QR code puzzle. The puzzle is a 3 x 3 grid (made on Powerpoint) with 9 questions. You coordinate the answers on an equally sized table (for exact placement of questions, use template, downloadable below). Print the questions on one page, but the answers and QR code page, print front to back and cut out. The students place the correct answers on the question, face down so that the QR side is up. when they place the pieces correctly, they can scan the QR code and a picture will show up! (Make sure all edges are as in line as possible. Even if it isn't perfect, it will still scan).
