The Areas of Squares and Their Side Lengths

In this video lesson, students explore: if we know the area of the square, what is the side length? Students estimate side lengths of squares with known areas using tools such as rulers and tracing paper (MP5). They also review key strategies for finding area that they will use to understand and explain informal proofs of the Pythagorean Theorem.
