Square Roots (Perfect Squares)

This free printable worksheet helps 7th and 8th graders learn the square roots of the perfect squares from 4 through 225 — the exact-root facts that the Pythagorean theorem and Algebra 1 assume are automatic.

How to Solve Pre-Algebra

Ask which whole number multiplied by itself gives the number under the root sign: √144 = 12 because 12 × 12 = 144. Memorize the perfect squares from 2² to 15² and each root becomes instant recall rather than a calculation.
