For parents and teachers
For learners who can add and take away numbers up to 100, such as 46 + 7 and 50 − 8. In many schools this fits children of about 8 to 10, and older learners who get lost in column sums can start here too. Activities use sticks, beans and paper. A learner can work alone: every exercise has its answer and the reason for it.
