Exemplars (from the NaCCA curriculum)
E.g. 1 Give pupils a standard graph sheet with 1 cm squares and ask them to draw a square of given length on the graph sheet. The area can be measured by counting the number of square units. So, we can count the number of unit units to find the area. In the diagram the area is 16cm 2 since there are 36 squares in the shape
E.g. 2 Ask pupils to count the number of cubic squares on the vertical section of the shape and multiply it by the number on the horizontal section Ask pupils to compare their answer with the first strategy and draw their own conclusions. The area of a square can be given as L × L and that of a rectangle is L × B.
