Unit 4 Equations – 10 days 

1  4.1 Solve Simple Equations

Solve one and two step equations. Student complete examples in class with and without algebra tiles.

Algebra Tiles & Balance Scale. Computer Algebra System (TINspire) 
2  Using Pentominoes to Solve Problems  Challenge: Fit a pentomino on the number chart so that a particular sum is achieved. First method: guess and check. Second method: generate equations to determine the location of the pentomino.This can be completed in pairs. After demonstrating the method, can have a class relay to see which group can solve the most problems.
