About Polygon Name Match
Polygon Name Match helps Grade 4 and 5 learners connect the names of polygons to their defining property: the number of sides. Down one side are polygon names — triangle, quadrilateral, pentagon, hexagon, heptagon, octagon — and down the other their side counts; the child draws a line to join each name to the correct number. Learning the vocabulary of shapes and the property that defines each one is a core geometry expectation across the US, UK, Canada and Australia, and it builds the precise mathematical language children need to describe and classify two-dimensional shapes. Presenting it as a matching task keeps the practice active and lets children compare several polygons at once, helping the naming pattern stick. The five levels vary which polygons appear so the worksheet stays fresh. Each page prints cleanly on a standard A4 sheet, and every level downloads with its own answer key listing the correct side count for each polygon. There is no advertising, no sign-up and no data leaves the device. Use it to build geometry vocabulary or alongside our shape games for the same age range.

- Is an answer key included?
- Yes, every level lists the correct side count for each polygon.
A hand for grown-ups
- Before you start
- Point out a few shapes in the room first. Geometry starts with noticing, and it is everywhere.
- While they work
- Encourage them to turn shapes around and look from different angles — literally, with a real object if there is one.
- Afterwards
- Go on a shape hunt around the house together. Naming real shapes cements the vocabulary.
- Watch out for
- Thinking a rotated square is a "diamond", or that size changes what a shape is. Turning a real cut-out shows it is the same shape.
- Away from the screen
- Spot shapes on a walk, build with blocks, fold paper into shapes. Talk about corners and sides.
