Exemplars (from the NaCCA curriculum)

E.g. 1. Learners model mathematical statements from a given word problem involving addition and multiplication and solve using the strategies learnt
E.g. 2. Learners model mathematical statements from a given word problem involving division and subtraction and solve using the strategies learnt
E.g. 3. Learners role play a given word problem involving addition and multiplication and solve
E.g. 4. Learners role play a given word problem involving subtraction and division and solve
E.g. 5. Learners model mathematical statements from a given word problem involving division and multiplication and solve using the strategies learnt. The relationship between operations and the use of calculator and spreadsheet to assess the reasonableness of answers should be stressed.
