Subtracting 2
✌️ Subtracting 2 means taking two backward hops. Or, you can just think about skipping numbers!
Do this: Read the concept below, then try the quiz or activity.
Concept
When you subtract 2, you are taking away a pair of things.
🎯 The "Count Back Two" Strategy: Example: 8 - 2 = ? Put 8 in your head. Now, count backward two numbers: "7... 6". So, 8 - 2 = 6.
🎯 The "Skip Backward" Trick: If you know how to skip-count by 2s (2, 4, 6, 8, 10...), subtracting 2 is just going backward on that path! If you throw a ball from 10 and it bounces back 2 spaces, it lands on 8. 10 - 2 = 8.
Try it
Let's do some double backward hops!
Instructions: Count backward two spaces to find the answer.
