Sorting Out Explain Everything
There are lots of great things in Math being done with the app Explain Everything! Explain Everything has been the go-to app of choice for many teachers, students to showcase learning and understanding.
Students in my class have used this app to explain major concepts from the course. For example, a student used the app to create a video on the differences between Direct and Partial variation.
The app can be used for other great uses besides video recording…
I have been using the app to create short Sorting activities.

The white space in the app allows users to easily move, rotate, and sort images on the screen. In the example above, as a warm up my students were asked to sort the solution to the equation in the correct order. We then had discussions on steps to solve equations.
Below is another sorting activity on sorting out linear relations. They were asked to match up tables, graphs, equations, and descriptions.

Another sorting activity: For MPM2D or MCF3M or MCR3U – Sorting the Quadratic Formula. Students were asked to sort out solutions to solving equations by completing the square. After sorting a number of solutions, they were asked to sort the general development of the Quadratic Formula.

With Explain Everything’ ease to make how to videos, and sorting activities…..it’s a must have on your iPads.

Thanks to Fawn Nguyen for this lesson idea. Her original blog post on this lesson is here. I did this lesson with my Grade 9 applied class and it went over great!!

What did you wonder? ….. How much the car was pulled back to make it go 117 inches?
Here’s what we did to help answer that.
Everybody got a car.
Then we set up tape measures on the ground….
We made trial runs with out cars and recorded our results on a handout.
We graphed our data in Desmos and fitted a function to model.
Use the following pre-made Desmos page… https://www.desmos.com/calculator/f6pjwnqhux
Students had to interpolate the data to estimate how far to pull the car back to make it go 117 inches.
