1. Balance Scale Addition
• I can balance an equation using addition.
• I need a balance scale and blocks.

2. Balance Scale Addition
• I count three blocks on the left.
• I place three blocks on the scale.

3. Balance Scale Addition
• I count five blocks on the right.
• I place five blocks on the scale.

4. Balance Scale Addition
• I show the balance scale using my arms. The side with five blocks is heavier. It is not balanced. I need to add blocks to the 3 side.
• I add one block to the three side but the scale is still not balanced.

5. Balance Scale Addition
• I add one more block to make 5 on one side and 5 on the other.
• The scale is now balanced.
• I can show this on paper by drawing two circles to the three side.

6. Balance Scale Addition
• So 2 circles and 3 circles is 5 circles.
• = 5 =
• Or 3 circles and 2 circles is 5 circles.
• = 5
• All balanced and all done!
