Everyone Can Learn Math

The kids are prepping to participate in the Canadian Math Kangaroo contest happening this March. They’re both really enjoying the puzzle-like problems, especially the youngest. This is a problem he was working on today from the 2020 Grades 3-4 contest.

The figure is a 4x4 grid. How many squares in the figure (possibly different sizes) do not contain the black dot?

This problem is similar to other “how many squares” problems we’ve seen before, but I like this new variation.

Have your kids try it and share their answers!
