Algebra Tiles

2
**Algebra Tiles On a piece of paper. Draw and label each Algebra tile.**

Unit - value negative 1 (-1) Rod – value negative x (-x) Square – value negative x2 (–x 2) Unit - value positive 1 Rod – value positive x Square – value positive x 2

3
**Algebraic Expressions**

Represent each expression with tiles. 3x + 2 – 2x + 3 -x + 2 – 2x + 3x

4
**Combining Like Terms 2a + 2 – 2a2 – 3a -2a 2 – a + 2**

Represent the expression with tiles. Combine the terms that are alike. Write new expression in simplest form. Remember: (+1) and (-1) make zero Remove all zero pairs. 2a + 2 – 2a2 – 3a Remember: Write your answer from largest to smallest exponent. -2a 2 – a + 2

5
**Adding Polynomials (-4 + 2y) + (2y2 – 3y + 2) 2y2 – y - 2**

Represent the expressions with tiles. Combine the terms that are alike. Write new expression in simplest form. (-4 + 2y) (2y2 – 3y + 2) 2y2 – y - 2

6
**Adding Polynomials Practice**

Represent each expression with tiles. Combine the terms that are alike. Write new expression in simplest form. (x2 – 3 + 2x) + (x2 – 1 + 4x) (5 + 2g2 – 3g) + (– 2 – g2 – 2g) (3p2 + 2p) + (– 3p + 4 – p2) (6m + 2m2 – 3) + (m2 –m – 5) (y + 2y2 – 4) + (2y – 3y2 – 2) 2x2 + 6x – 4 g2 – 5g + 3 2p2 – p + 4 2m2 - 5m – 8 -y2 + 3y - 6

7
**Distributive Property**

Represent the expression with tiles. Combine the terms that are alike. Write new expression in simplest form. 2 (x2 + 2x – 1) 2x2 + 4x – 2

8
**Distributive Property**

Represent the expression with tiles. Combine the terms that are alike. Write new expression in simplest form. 3 (-x2 -2x + 3) -3x2 -6x + 9

9
**Distributive Property**

Represent the expression with tiles. Combine the terms that are alike. Remember to do the opposite for (-) Write new expression in simplest form. - (-2x + 3) 2x - 3

10
**Distributive Property**

Represent the expression with tiles. Combine the terms that are alike. Remember to do the opposite for (-) Write new expression in simplest form. -3 (x2 + 2x - 1) -3x2 - 6x + 3

11
**Distributive Property Practice**

Represent the expression with tiles. Combine the terms that are alike. Write new expression in simplest form. 2(2x + x2 – 1) 3(2g2 – 3g – 2) -(-3p2 + 2p + 4) -3(2m2 – m + 2) -2(2y – 3y2 + 5) 2x2 + 4x- 2 2. 6g2 – 9g - 6 3. 3p2 – 2p - 4 4. -6m2 + 3m – 6 5. 6y2 - 4y - 10
