The best way to learn about weight is to handle the weights and get 'a feel' of how much something weighs. The gram is a very small weight, so the kilogram is much better to handle, although this is rather heavy! This is probably one of the reasons why the British have been reluctant to give up their beloved pounds and ounces. It would be really useful to have have a set of metric weights and a set of balance scales. This Year 2 maths worksheet asks the child to find four objects that they think weigh less than a kilo and then asks how to find out whether they are correct. If you don't have a kilo weight there are many food items which have the weight on which could be used. (4 packs of butter at 250g each etc.) The second task is to try and put their 4 items in order from lightest to heaviest. This can be done by comparing two and placing them in order and then comparing the third with the first two, and so on. Even easier if you have a set of metric scales! The third task is to try and find four objects that weigh about the same as a kilo. This will help with getting a good idea of what a kilo actually feels like. Go to our Kilo maths worksheet
