As an introduction to linear direct variation, I put together a quick problem-based learning task that was proportional for my combined academic & applied class:
What do you notice?
I had to use the Pear Deck dashboard to hide some responses that involved calculating the price per calculator as this was part of solving the later problem. I suppose I could have left them up, but I wanted to leave the calculating part until later when students were in their groups.
What do you wonder?
How much would it cost to buy a class set of 25 calculators?
Best estimate: ________$
You can find the Pear Deck slideshow in this folder. Also in the folder is a follow up slideshow exploring the concept of Direct Variation.
