Finding 1, 10, or 100 More/Less
Students practice adding and subtracting 1, 10, or 100 to/from any given number up to 1000.
Key Questions
- Predict how a number changes when you add 100 to it.
- Explain the pattern observed when repeatedly subtracting 10 from a three-digit number.
- Compare the effect of adding 10 versus adding 100 to a number.
