A “square” is the product of any number multiplied by itself. When you hear someone say “25 square feet” what it means is that 25 squares of 1 foot x 1 foot fit into the area. We say “square” because a number multiplied by itself can create a square if you draw it out on a grid.
Here’s two challenges:
- How many different squares can you fit on this grid multiplication strategies 5a?
- How can you use different squares to fill as much space as possible on the grid?
