1. Warm Up www.tinyurl.com/shsalgtile
Build x2 + 3x + 2 out of algebra tiles.

2. 3.2.1 Modeling Area & Perimeter with Algebra tiles
HW: 3-77,81
October 18, 2018

3. Objectives
CO: SWBAT build rectangles with algebra tiles and write the area as a sum = area as a product.
LO: SWBAT discuss with their teammates how to build a rectangle.

4. 3-75. For each polynomial below, build a rectangle using all of the algebra tiles.  Sketch each rectangle, and write an equation that shows that the area written as a product (like (x + 3)(x + 2)) is equivalent to the area written as a sum (like x2 + 5x + 6). = #
