1.10 Numbers guide

4. Simple calculation up to 100.

The point is to differentiate between ones and tens (e.g. forty and forteen)

Examples

  • 50 plus 40 is ...
  • 5 plus 40 is ...
  • 5 plus 14 is...
  • 15 plus 40 is...

So use pairs: 13  - 30; 14 - 40, etc.

5. The learner has to ask you similar questions.

Ask after each of your answer: is it correct? Give incorrect answers sometimes.
