Square Roots and the Pythagorean Theorem
"In this unit, students will explore perfect squares and square roots. They will relate the side lengths of squares to square roots and the areas to perfect square numbers. They will determine if numbers are perfect squares through the use concrete materials, such as grid paper or pattern blocks, as well as using prime factorization and examining the factors of the given numbers. Students will estimate the square root of a non-perfect square to the nearest tenth. Students will develop the Pythagorean Theorem through exploration and use their previously learned knowledge of squares and square roots to determine the lengths of sides of right triangles. The Pythagorean Theorem is used in many fields including architecture and construction, navigation, and surveying. Exploring such situations will strengthen student understanding of the concepts in this unit." - Grade 8 Curriculum Guide
