Exemplars (from the NaCCA curriculum)

E.g. 1. Have a picture of learners in front of the class and ask the learners to use two different pictures/objects to represent the number of males and females. Repeat with pictures of animals
E.g. 2. Using a one-to-one correspondence to solve simple problems (i.e. how many altogether, how many more or less) problems requiring interpretation of the concrete representation of pictures as in E.g. 1 above
