In KS2 Year Six, children should be quite comfortable when dealing with measures in Maths. By now they should be well aware of the metric measures (mm, cm, m, km, g, kg, tonnes, ml, cl and l) and know some of the imperial measures (pint, gallon, mile etc.). They should also be able to convert smaller and larger units and combine the two (eg. 2.8 m = 280 cm = 2m 80cm). They will now be introduced to the imperial units of weight – ounces, pounds and tons, and how they relate to grams, kilograms and tonnes.
Tons, stones, pounds and ounces are all types of measures. They are all used to measure weight, but nowadays tonnes, kilograms and grams are more common. Babies used to be weighed in pounds and ounces when they were first born. These days, they are weighed in grams. Are you able to change from pounds and ounces to grams quickly and easily?
