42 = 8 42 = 4 ● 2 = 8
42 = 4 ● 4 42 = 16 Not all even numbers are perfect
squares.

Let’s ReviewGuided Practice
How many perfect squares are there between 200 and 300?

Let’s ReviewExtension Activities
While squaring a number means to multiply a number by itself, cubing a number means to multiply a number by itself three times. So a perfect cube is the result of cubing an integer. This means 8 is a perfect cube because 2 x 2 x 2 = 8. How many perfect cubes are there between 0 and 1000?

Let’s ReviewExtension Activities
Find as many sets of three perfect squares where the largest of the three perfect squares is the sum of the two smaller perfect squares. For example, one set is 9, 16, 25 because 9 + 16 = 25.
