Trig Pixel Art Review

I gave a quiz this past week. Some students did quite well but others struggled with some of the concepts. I wanted an activity that gave more practice of the skills students were missing but was self-checking. Students have been asking for another pixel-art activity so I decided to combine the two.

This week in the United States is Groundhog Day. You can click here and read about the history of Groundhog Day. It’s very interesting! One of my colleagues and friend grew up in Punxsutawney Pennsylvania, home of the official Groundhog. When we are NOT in a pandemic, she makes groundhog shaped sugar cookies for all her students and the other math teachers. I know this year she is sad because she won’t be able to share this tradition. To honor her hometown, I made this pixel art activity as a groundhog :-). This one is for you Danyelle.

You may take this one and alter it. You may also create your own with this tutorial I created.

I also wanted to share a couple of Desmos activities I found and used during this unit. Both are by Kurt Salisbury.

The Zelda activity is one I’ve used before and I really like it. It practices Pythagorean Theorem.

The second one I found just this year and it is AH-Mazing!!! I will be this good at Desmos CL one day and will make fun things like this! This is one is an intro to Trig with some terrific animations. It really allowed my students to think an explore.

As always, I hope you find this useful!

Trig Exit Tickets

Here you go, some Exit Tickets for a Trig Unit.

Just some friendly reminders of how I use this.

  1. Have students correct until they get the correct answer.
  2. Give comments on the slide to help direct them.
  3. If you have given more than 2 comments, conference with the student so they don’t get frustrated.

I hope you can use these. If you want to edit them, go to edit, master and you can change the information.

Student Created Trig Word Problems

For the last 9 years, I’ve had students do a Trig project where they use handmade clinometers to measure the height of an object taller than they are. I love this project because it shows the application of Trig and guides students through a thought process to solve this type of problem.

This year I wanted to shake things up a bit. I wanted them to do the same project, but this time I wanted them to write an angle of elevation word problem. Students struggle with the word problems, and writing them helps them understand the process and required information.

As always, I was blown away by the creativity of some of my students. Their word problems were hilarious! They were problems I would WANT to solve. I took a few and used them on our assessment.

Since we had a recent ice storm, pictures had to be taken inside. It was Homecoming week, so we had some interesting backdrops. Students used the HOCO decorations and wrote their stories around them. Aren’t kids great?

Angle of depression is still giving us issues so maybe next year I’ll have them measure something below them. Maybe from the bleachers or the top of the steps. Hmm… food for thought!
