You can find out how big an area is by covering it with equally sized squares.
Here's how:
1. Look closely at the colored shape on the grid.
2. Count all the colored squares. A small tally mark in each counted square helps.
3. Write the number of squares in the answer box.
The numbers filled in show the solution.

For parents
What does this exercise practice?
This exercise builds understanding of area by covering surfaces with unit squares and counting them.
Common pitfalls
Children often miscount with irregular shapes or count squares twice. It helps to count row by row and mark each counted square.
How to practice at home
Cover surfaces with playing cards or sticky notes, for example a book or a tray, and count the pieces.
