This activity provides the learners with lots of practice in adding and subtracting. When a number is placed at the top of the pyramid, they must understand how to use addition to help work out subtraction.
Practice in addition and subtraction sums.
- Learners get the 3rd level pyramids and use various methods to add up, starting with single-digit numbers at the bottom given to them by the facilitator.
- When they are more fluent, move onto the 4th level pyramids and use a mixture of 1 and 2-digit numbers as this will extend the number range.
