I can use Algebra Tiles to model solving one step equations using inverse operations (addition or subtraction)
In class:
2.4 Solving Equations using Addition or Subtraction
- Students were introduced to Algebra Tiles to model solving one step equations
-Practiced using Algebra Tiles to solve one step equations
-Recognize the inverse relationship between addition and subtraction.
Example:
**** Remember to use the INVERSE operation on BOTH sides of the EQUATION*****
**** START on the SIDE with the VARIABLE*****
- Homework: (Draw the Algebra Tiles for each problem!) See the above example!
- 2.4 Packet
- pg 41 Example #2
- pg 42 Activity #3 problems a-d
I can solve a one-step equation using inverse operations (addition/subtraction)
In class:
2.4 Solving Equations using Addition or Subtraction
-Transitioned from Algebra Tiles to solving equations using the "algebra method". Showing "adding the opposite" to both sides of an equation.
Homework:
Pages 42-43 in your 2.4 packet (be sure to show ALL steps on BOTH sides of the equation)

I can solve a one-step equation using inverse operations (addition/subtraction)
In class:
2.4 Solving Equations using Addition or Subtraction
Focused on solving equations using the "algebra method". Showing "adding the opposite" to both sides of an equation for more complex one-step equations (decimals and fractions).
Homework:
page 44 in your packet (BACK PAGE)
problems 1-6 (YOU MUST show the STEPS when solving the problems)
The process is as important as the correct answer!
Steps to Solving a one step equation:
- Always start on the side of the variable
- Add the opposite/show the inverse operation on BOTH sides of the equation
- "Whatever you do to one-side of the equation, you must do unto the other side of the equation"
- Check your answer by substitution
