Exemplars (from the NaCCA curriculum)

E.g. 1. Display a number chart with numbers between 0 and 100 and have learners identify numbers in different positions around a given number. Put learners in convenient groups and give each group a number grid and have them identify numbers in different positions around a chosen number. For example, choose 18 and identify numbers above, below, to the right or to the left etc.
