Lesson 6: Coordinate Distance & Review

How can we find the exact distance between two points on a grid without counting diagonally or memorizing a new formula?

How do horizontal ("run") and vertical ("rise") changes on a coordinate plane relate to the legs of a right triangle?

How can we connect exponent rules, scientific scales, radicals, and right triangles to solve complex structural problems?

8.G.B.8 (Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.)

Review of: 8.EE.A.1`, `8.EE.A.3`, `8.EE.A.4`, `8.NS.A.1`, `8.NS.A.2`, `8.G.B.6`, and `8.G.B.7`

replacing the abstract Distance Formula with a visual Pythagorean Theorem approach.

DOK Level: 2 (Skills and Concepts) and 3 (Strategic Thinking/Assessment Synthesis)

Students often try to find distance by counting grid squares diagonally across the line segment rather than creating horizontal and vertical component legs.

Provide sheets with high-contrast coordinate grids.
