Estimating Area WORKSHEET
Estimating Area WORKSHEET DESCRIPTION
Once pupils have found the area of rectilinear shapes by counting squares they can start to estimate the area of irregular shapes using the same method.
In section A, will estimate the areas of six different shapes constructed using straight, diagonal and curved edges drawn on a cm square grid and then write these areas in ascending order.
Section B is a similar task but here the shapes contain no curved edges and students are encouraged to use parts of squares to help them.
All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions
Before tackling irregular shapes, Year 5 students should be comfortable finding the area of rectilinear shapes by counting unit squares on a grid. This foundational skill of square counting provides the basis for estimating areas when shapes don't fit neatly into whole squares. Once they've mastered this systematic approach with regular shapes, they're ready to apply similar thinking to more complex irregular forms.
