Exemplars (from the NaCCA curriculum)

E.g. 1 Play the place value number wheel game: Use the million number wheel to generate 7-digit numbers and represent the number generated on a place value frame. Throw a number of pebbles (or stones) onto the number wheel, identify the number of pebbles landing in each place value ring, and state the number generated in the wheel (i.e. 5 landed in the hundred-thousands' ring making the number twenty-thousand or 500,000). NB: The representations to use also include verbal, and numerals. Learners must match number word cards to the figures

E.g. 2. Ask pupils to write given numbers on the expanded form of the number : 1,362,524,513 = 1,000,000,000 × 1 + 100,000,000 × 3 +10,000,000× 6 1,000,000 × 2 + 100,000 × 5 +10,000× 2 + 1,000 × 4 +100 × 5 + 10 × 1 + 1× 3 = 1,000,000,000 + 300,000,000 + 60,000,000 + 2,000,000 + 500,000 + 20,000 + 4000 + 500 + 10 + 3
