Quick Tip
Teacher Resources
Teaching Notes
Combines multiple addends with place value understanding. Strategy: Think about the hundreds digit only (2+3+4=9), then add zeros. This reinforces that place value rules apply consistently across all positions.
Vocabulary
Common Mistakes
- Mixing up place values
- Adding only two of three numbers
- Writing 90 instead of 900
- Forgetting to include all addends
- Forgetting to write the two zeros in the hundreds place, resulting in answers like '6' instead of '600'.
- Confusing adding hundreds with adding tens or ones without proper place value understanding.
