About this resource
Count square-centimetre units to find the area of four shapes. Record the covered area beside each grid figure.
- Four figures drawn on square-centimetre grids
- Area response spaces adjacent to the shapes
- A stated one-square-centimetre unit scale
Curriculum reference — Ontario: Metric unit scale is portable; no imperial conversion needed. Counting equal non-standard squares supports Grade3 area measurement; no centimetre-unit claim unless shown. England Year4 explicitly includes counting squares to find area. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.
