Exemplars (from the NaCCA curriculum)
E.g. 1 Determine the products when one factor is a multiple of 10, 100, or 1000 by annexing zero or adding zeros (e.g., for 3×200 think of 3×2 and then add two zeros) E.g. 2 Apply halving and doubling when determining a given product (e.g., 32×5 is the same as 16×10) E.g. 3 Apply the distributive property to determine a given product involving multiplying factors that are close to multiples of 10 (e.g., 29×7 = (30×7) - (1×7) = 203
