Exemplars (from the NaCCA curriculum)
E.g.1 Convert (cm to m; km to m; ml to cm; etc.) one unit of measure to another using ratio reasoning. • 1m = 100cm is a conversion factor, and we can write from it the ratios 1 m and 100 cm , with each being equivalent to 1. Then, to 100 cm 1 m convert a measurement in metres into centimetres, we can multiply it by the ratio 1m/100cm. E.g.2 Manipulate and use units appropriately to solve problems. • Agbo walks 4km to school every day. He uses 60minutes. Rukiya uses 45minutes to cover 4200m. Which of the two learners is faster?
