Use the tool to slide the magnifying glass around and reveal the hidden numbers! When you find a product of 5, change the color to make it visible. Watch the video to see how it is done. When you are finished and have changed the color of all of the products of 5, you may submit!
I got this idea from Mrs. Talk Techie who used this in google slides. Her tutorial video is here: https://www.youtube.com/watch?v=9LwHs-CSobo.
