P4 weighed some shopping items in grams. They had to read the scales then put the items in order – lightest to heaviest.
P3 found things in the classroom to weigh to find things heavier than and lighter than 1 kilogram. They checked that two half kilogram weights equalled 1 kg.
We had a surprise visit from Lyall and Jake with a very interesting old weighing balance used for weighing bull skins. We filled Mrs. Thomson’s shopping bag with lots of weights and the shopping (Mrs. Thomson could hardly lift it!) and we weighed it on the balance. It was over 20 kilograms!
