The lesson objective is for students to explore the equal sign and its relationship to values, understand that performing the same operation on both sides of the equal sign is necessary to solve equations, and use inverse operations to solve one-step algebraic equations. Students will use balances to represent equal equations and learn that the scale must be balanced. The lesson will review vocabulary and have students work independently on practice equations.

1. Unit 4 Lesson 7
Objective:
• Students will explore the equal sign and its relationship to two values.
• Students will understand that performing the same operation on both
sides of the equal sign is necessary for solving equations with variables.
• Students will use inverse operations to solve one-step algebraic
equations

2. Let’s review our vocabulary!
True/False
• Variable 7b + 9
• Term 6 + 9b - u
• Coefficient 7(8+7)=56+49
• Constant 17b + 17
• Pattern 2,4,5,6,8,10…
• Distributive property 8+(3+2)=(8+3)+2
• Commutative property 9+3=3+9
• Expression z
 Objective: Students will practice working independently on equations from
lessons 3-6

Today’s Investigation: Equality in the
Balance
Today we are going to use our balances to help us write balanced algebraic
equations. The most important goal for today is that the scale must balance
