Today I am practising: changing the tens value while preserving ones
1
Write ten more than 34. Which digit changes?
2
Write ten less than 76.
3
Complete 48 + 10 = ___ and 48 − 10 = ___.
4
A learner says ten more than 52 is 53. Explain the amount added in that answer.
5
Find a number for which ten more is 89.
6
Choose a number from 20 to 80. Write ten less, your number and ten more.
- Add or remove a drawn tens bundle rather than individual marks.
- Ask the learner to identify the unchanged ones value.
- Keep chosen values within two-digit results.
