Grade 3 geometry worksheets
Our grade 3 geometry worksheets review two dimensional shapes, particularly circles, triangles, quadrilaterals and polygons. We also focus on the definition and classification of lines and angles. The areas and perimeters of rectangular shapes are reviewed, as are the concepts of congruency and symmetry.
