Algebraic Reasoning
Hello my smart Grade 3 friends! Today Miss Kashef will teach you about equality (balance) and solving for unknown numbers. We will use scales, boxes, and simple equations with lots of examples so you feel confident!
What is Equality?
Equality means both sides are the same — like a balanced scale.
5 + 3
= ⚖️ =
4 + 4
Solving for Unknowns
5 + □ = 9
□ = 4
□ + 7 = 12
□ = 5
Fact Families Help Us
6 + 8 = 14
8 + 6 = 14
14 - 6 = 8
14 - 8 = 6
Balance Scales
7 + □
⚖️
12
□ = 5
More Examples
9 + □ = 15 → □ = 6
□ - 4 = 8 → □ = 12
20 - □ = 13 → □ = 7
