1. Multiplication and Division Equations (Day 1 Multiplication Equations) We are learning to…use inverse operations to solve for a variable in an equation. Thursday, September 10, 2015

2. Find the following Algebra Tiles… Trace each of these Algebra Tiles on your notes. 1 unit x units Area/Name: “1 UNIT TILE” 1 unit Area/Name: “X TILE” Area/Name: “Y UNIT TILE” y units 1 unit Name each tile by its area. 1 unit The red side of each tile represents… one negative unit! The other (“non- red”) side of the tile represents… one positive unit!

3. Multiplication and Division Equations  The variables, x and y, represent missing values in our equations today.  Our job is to find the value of the variable by isolating the variable on one side of the equation.

4. Example #1 = Record your steps mathematically: Check your Solution:

5. Example #2 = Record your steps mathematically: Check your Solution:

6. Example #3 = Record your steps mathematically: Check your Solution:

7. Example #4 = y y Record your steps mathematically: Check your Solution: y y

8. Example #5 = Record your steps mathematically: Check your Solution: x x x x x x

9. Team Practice  With your team: 1.Set up each equation on your Equation Mat using your set of Algebra Tiles. 2.Draw what you see on your Equation Mat as you solve each equation. 3.Record your equation solving steps mathematically. 4.Check your solutions by using substitution.
