Algebra - Week 3 Lesson 2: Solving Equations (One-step)

Lesson:

• Equations contain an equal sign. The focus of this lesson is to isolate the variable on one side of the equation.

• The can be done by using the  ‘change side, change sign’ rule.

• We inverse (opposite) operations to cancel out the terms on the side with the variable. Whatever you do to one side, you must also do to the other side.

Ex 1:

• a + 2  = 10

• a = 10 - 2

• a = 8

Algebra - Week 3 Lesson 3 - Solving Equations (Two-Step)

Lesson: 

This lesson will be a continuation of the last lesson but will progress to two-step equations. 

Example: 2a + 5 = 13

1. Subtracting 5 fro both sides: 2a = 13 - 5
   
2. Divide both sides by 2: 2a = 8

Work in Class:

• Worksheets

• 2 step equations (multiplication)

• 2 step equations (division)

Extension:

• Worksheet

• 2 step worksheet (mixed operations)
