Unit 8
Pythagorean Theorem and Irrational Numbers
Unit Narrative
This unit introduces students to irrational numbers with a focus on connecting geometric and algebraic representations of square roots, cube roots, and the Pythagorean Theorem.
In the first section, students extend work from grade 6, composing and decomposing shapes to find the areas of tilted squares. They see “square root of ” and to mean the side length of a square with area square units, and understand that finding the solution to equations of the form means determining which values of make the equation true. Students learn and use definitions...
