This project is a bundle that will help teachers implement Scratch programming inside of their classroom. This lesson aligns with a unit on the Pythagorean Theorem. This lesson should deepen the understanding the students have on right triangles. This bundle includes, a project goal, the aligned standards, the blocks that the students will need to use to create the program, a student exploratory guide, a step-by-step teacher guide, and a solution to the program. In this lesson students will create a program that asks the user to input three side lengths of a triangle. The program should tell the user if the side lengths create a right triangle or not.
