About these worksheets
These worksheets cover shape identification across multiple levels. Students name basic 2D shapes by their sides and corners, identify quadrilaterals, recognize regular and irregular polygons from triangles through decagons, classify right triangles, identify solid 3D figures, determine which shapes combine to form a figure, and classify triangles by angles and side lengths. Resources span first through fourth grade and beyond.
3g1
- Name a regular polygon by counting its sides (triangle through decagon).
- Use the words triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon correctly.
- Tell that a shape is regular by noticing its equal sides and equal angles.
- Count sides and vertices carefully to avoid mixing up similar-looking polygons.
3g1
- Count the sides and corners (vertices) of a polygon to figure out what it is.
- Name irregular polygons as quadrilaterals, pentagons, hexagons, heptagons, octagons, nonagons, or decagons.
- Use shape clues like sides, angles, and vertices to choose the correct polygon name.
3g1
- Identify common polygons by name when you read a short word problem.
- Count and match the number of sides to the correct shape.
- Use shape clues in a sentence (like “has 8 sides”) to choose the right polygon.
3g1
- Decide whether a polygon is regular or irregular by checking if all sides and angles match.
- Spot shapes that look similar but are irregular because one side or angle is different.
- Use words like side, angle, and vertex to describe why a shape is regular or irregular.
- Compare different polygons and sort them into regular and irregular groups.
