Sometimes you need to count half squares to find the area of a figure.

1 whole square +  2 half squares
2 half squares = 1 whole square
1 + 1 = 2 square units

 

Sometimes you need to estimate the area of a figure.


4 whole squares + 4 almost whole squares + 4 about half squares

4 half squares = 2 whole squares

4 + 4 + 2 = about 10 square units
