This project is a bundle that will help teachers implement Scratch programming inside of their classroom. This lesson aligns with a unit on functions. This lesson should deepen the understanding the students have on input and output tables. 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 function (ex. f(x)= 2x + 3). Given an input/output table, the user will try and guess the function.
