This unit starts on Thursday Dec 3rd 2009

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.

  • H.W. Pg. 193 #1-9 eol
Algebra Tiles & Balance Scale. Computer Algebra System (TI-Nspire)
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.

  • HW. Complete the worksheet (given out in class)
