As promised last week, here are some exit tickets that you can use with a Similarity Unit in Geometry. Just a reminder of how I use these. I give feedback on each submission and have students work on them until they are correct. I love doing this with the comment feature in Google Slides. In Canvas, I am using the Google Assignments LTI so it looks just like Google Classroom.
Now, you might not want my Bitmoji on your slides. I mean, she’s cute, but I get it! You can go to view-master and change the Bitmoji there. I changed my jacket color for each day. One student told me he was excited each day during the lesson to see what color the jacket would be but slightly less excited about the math. 😂 Whatever gets them there!
It’s nice when you find an activity that you can just USE. If you are getting ready to teach or review triangle congruence, hopefully these exit tickets will be helpful.
I give these the same day I teach a new lesson. Students get feedback from me until they have correct answers. It has worked very well during our hybrid schedule but I plan to keep doing it when we go back in person.
These slides are interactive so you will want to make a copy for each student. You can edit the content by going to view-Master. I create it there so the static parts don’t move.
Each one is set to template. If you would like to keep the activity, just select the get template button in the top right corner.
I am a huge proponent of application when application is possible. I realize sometimes application is not possible at the level you are teaching. For example, my senior son was working on Calculus the other day and had to recall the exponent rules from Algebra 1 (8th grade for him). He hasn’t needed to use exponent rules in any other class AND when I teach Algebra, I know it’s near impossible to find application for the rules. Clearly they have a purpose, but he didn’t see that purpose until four years later. Application wasn’t possible at the time he was taught the rules.
Surface area and volume, however, is VERY applicable. Last year, I switched my focus from using the formulas to finding online calculators (Read about it here) and just applying the formulas. I created many application type activities, including measuring objects in the classroom. We ended the unit with our robot project (referenced in the book Make Math Not Suck), which the students LOVE!
This year, I wanted to make my life and my student’s lives a little easier. There isn’t ONE calculator online that will calculate every surface area and volume problem we encounter. Teaching students the skills to look for these calculators is a good skill! The issue was the time involved searching for a calculator that would work, then when we did find one, there were some inappropriate ads on some of the pages.
So I fixed it! I created a SURFACE ARE AND VOLUME CALCULATOR that I can give to my students. They still need to know which one to use but they don’t have to search the internet to find one.
Please use this with your classes. Please DO NOT sell this to others or pass it off as your own. I drew each figure on my iPad and I entered each formula in the cells. It took some time! I LOVE when people use my stuff (for FREE) but it upsets me when they take it and sell it on TpT as their own. DON’T BE THAT PERSON!
Here are some quick links to previous posts about surface area and volume applications to use with the calculator and a BRAND NEW remote learning performance event.
I wanted to share with you a quick update to Road Kill Kafe that I use in my Geometry class to discover congruent triangles. It was shared with me by my friend Craig Klement (@CraigKlement) and you can read about all of my Triangle Congruence activities here.
We are hybrid this year and it usually takes 2 days to complete the activity. That’s 4 class days with both classes and we simply didn’t have the time to do that.
So… I turned it into a digital activity. It worked out ok. I did model some skills for them regarding the drawing tools in Google Slides and that made things go more smoothly. I also pasted a reference segment so we could make sure our side lengths were what they should be.
Here are some images of our completed triangles.
If this is your original activity, let me know! I would love to give proper credit. If you want to try Road Kill Kafe goes Remote, just click on the links below. The first one is the activity to send to students. Make a copy for EACH student. The second one is the collaborative slide with the reference segments for students to paste their completed triangles. Make sure you set it so EVERYONE has access to the same slide.
This pandemic has caused us to stretch our thinking and innovate to make the best learning environment for our students.
I love sending students to the whiteboard or having them use table whiteboards in the classroom to practice. With social distancing, I couldn’t get as many to the whiteboards as I needed to. I also have individual table whiteboards, but using the sanitizing cleaner on our them was eating the finish.
The solution came from two of my colleagues ideas. The first one was the individual bags with a cut up piece of towel. Students were asked, if they could, to purchase their own marker for the bag. I had a few for students who couldn’t or who forgot. This way they could use their own “eraser” and marker and we wouldn’t have to sanitize them.
The second solution was laminated paper with a grid printed on one side. Each student received one for the notebook. Now they can use their own and we don’t have to sanitize the desk whiteboards and ruin the finish.
The third part was laminating grid chart paper to put on the walls as extra whiteboard space. It works just as well as and erases just as well as the shower board my school uses for whiteboards.
I loved finally getting my students up and working problems. I love that they can look around and see what others are doing and self-correct. I love that it helps me see where students are with current material. We were able to get almost everyone to the new board spaces because we are now on a hybrid schedule with part of the alphabet each day. I need to make a few more for the wall and find some space to put them.
This pandemic has been something. Keep being awesome for your students but also keep taking care of yourself! It’s hard, but it won’t be forever!
What are number talks you ask? They are a wonderful low floor, high ceiling task that allows everyone the opportunity to share their thinking. Here is a Wakelet of resources I have compiled from the interwebs. I use Fawn Nguyen’s Visual Patterns a lot! A great book I recommend reading is Making Number Talks Matter by Cathy Humphreys and Ruth Parker. I’m sure there are others, but this is the one I read. There are many videos, blog posts, and ideas if you just google Number Talks. I like that Number Talks strengthen numeracy and allows students to see that everyone approaches problems differently, which is the wonderful thing about math. Many students, because of how they have been taught, think there is only ONE way to complete a problem.
As I mention in my book, Make Math Not Suck, I want my classroom to be a safe space. Because of this, I like to keep responses like this anonymous, allowing students to share if they feel comfortable. I started trying to do number talks in PearDeck using the drawing feature. The problem I ran into was wanting students to be able to draw OR write to explain their thinking.
Enter Desmos. With Desmos, you can give students the option to type or write. And when you are working with patterns, they can draw right on the pattern.
We move to hybrid learning this week. Half of my class will be in person and half will be joining by Zoom. I think Desmos is going to work well for our Number Talks in this situation. I can still select student responses to share on the screen that both in home and in person students can view.
If you aren’t using Number Talks, do a little investigating. I think you will find it gives students confidence, it allows you to see gaps in their number sense, and it helps students learn new strategies.
As I was perusing Twitter last week, I came across someone asking if their activity could be made into a Google Slide. For some reason I cannot resist the urge to “see if I can do it”!!! [On a side note, self care tells me I really SHOULD resist this urge ☺️] So I did it! I created a digital version of her game.
First, this game looks like a fun way to add three digit numbers, there is not one right answer, and students are not competing based on correct answer rather how close they get to 1,000.
I REALLY liked the “shuffle” idea I came up with for this game and thought, WOW, I could use the idea for a regular deck of cards. I began looking for a deck of cards and ran into a snag… I didn’t want to use someone else’s card due to copyright and I’m simply too cheap to buy them. So… I made them. Please don’t laugh at my King, Queen, and Jack. I did my best 😂. The good news is, they are free and Creative Commons licensed to me so just give me credit if you use them.
The instructions to shuffle are in both of activities. Make sure you don’t just drag the cards. You have to DUPLICATE the card or the layering will not be in the correct order. Once you have created your decks, you can copy the whole deck and paste it into any other Google Slide activity you have created. Create multiple slides, to have multiple “shuffled card” options.
After I made this activity, I saw the John Meehan (@MeehanEDU) had also made one. In his activity, he has a created deck of cards (his doesn’t “flip over” with the cover card) and he just changes the order. I couldn’t quickly find it, but he shared it on Twitter.
If you use either of these activities, give me a shoutout on social media. It makes my day when others can use what I share.
Decorations. Really?! Yes, because this is where I’m at right now. We have been teaching in a remote environment since school started. Not because of Covid but because we had black mold growing in our building and it had to be gutted and cleaned. I returned to my classroom Monday to take stock of what I needed. Sadly, I needed everything! They threw away EVERYTHING in my classroom.
I wanted an inviting space for my students, so I planned to spend the week trying to get my room ready, But, creating this last week of digital lessons, giving virtual feedback, answering emails, and scheduling extra Zoom tutoring sessions took up my time. On Thursday night I FREAKED OUT because I had no decorations in my classroom. I ran to JoAnn’s and bought some fabric for my curtains, Wal-Mart to replace the plastic bins, Dollar Store to buy some scissors, and a few other places for decor. I found NO DECORATIONS for a secondary math classroom. My solution, make my own.
I printed this Welcome banner last year from Math=Love. So I just printed a new set and stuck it to my door.
I also had an empty bulletin board. My giant Dumbledore and favorite quote gone forever. It was too sad to make a new one, so I opted for some Math Puns. I have provided the PDF if you want to print your own. Thankfully our school now has a color printer and I could print and laminate at school.
Bitmoji also has some new stickers PERFECT for the classroom.
I’m fairly pleased with the results. I will miss what I lost, puzzle books, decorations, all my stress squishies, and 20 years of memories and student work, but we will move forward and make the best of it.
If you use the Math=Love banner, tag Sarah Carter on Twitter (@mathequalslove). If you use the math puns, tag me on Twitter (@MandiTolenEDU).
I hope you have had a great start to you year. Keep being awesome for your students!
