1. How to Use Algebra Tiles

2. What are Algebra Tiles????? X X2X2 Red = Negative Numbers Yellow = Positive Numbers A Small Square = 1 A Rectangle = X A Large Square = X 2

3. How do I use Algebra Tiles? 1 + 4 = 5 1 + x = 5 1 + x 2 = 5 If you see Then you build If you see Then you build

4. How do I use Algebra Tiles? -1 - 4 = -5 -1 - x = -5 -1 - x 2 = -5 If you see Then you build If you see Then you build

5. Now What????????????????

6. How do I use Algebra Tiles? 1 + 4 = 5 If you see Then you build 1 + 4 = 5 If I subtract from side of the equation, I have to subtract from the other side 0 + 4 = 4 4 = 4

7. How do I use Algebra Tiles? 1 + x = 5 If you see Then you build 1 + x = 5 If I subtract from side of the equation, I have to subtract from the other side 0 + x = 4 x = 4

8. How do I use Algebra Tiles? -1 - x = -5 +1 0 - x = -4 -x = -4

9. How do I use Algebra Tiles? 1 + x 2 = 5 If I subtract from side of the equation, I have to subtract from the other side 0 + x 2 = 4 x 2 = 4 x2x2 x2x2 x2x2 x = 2
