What Your Child Will Learn
Grade 3 geometry focuses on classifying two-dimensional shapes by their properties, including the number and type of angles and whether sides are parallel or perpendicular. Students learn to identify right angles using the corner of a piece of paper as an informal tool and distinguish angles that are greater than or less than a right angle.
Students also study the properties of prisms and pyramids in more depth, comparing the number of faces, edges, and vertices, and relating these figures to their nets. Symmetry work expands to shapes with more than one line of symmetry, and students practise creating symmetrical designs. Position and direction is formalized through simple coordinate-like grids, where students plot and describe locations using rows and columns.
Skills Covered
- Identifying right angles and comparing other angles to them
- Classifying shapes by parallel and perpendicular sides
- Comparing faces, edges, and vertices of prisms and pyramids
- Relating 3D objects to their nets
- Identifying and creating shapes with multiple lines of symmetry
- Plotting and describing locations on a simple grid
Curriculum Aligned: Aligned with Strand E (Spatial Sense): classifying two-dimensional shapes and three-dimensional objects by their geometric properties.
Parent Tip: Use the corner of an index card as a homemade right-angle checker — comparing door frames, book corners, and picture frames to it is a simple, effective way to practise angle comparison.

Why is geometry important in math?
Geometry develops spatial reasoning, logical thinking, and proof skills. It connects math to the physical world through shapes, measurements, and transformations.
How can I support geometry learning at home?
Build with blocks, identify shapes in the environment, measure rooms, and use drawing tools. Hands-on activities make geometry concepts concrete.
What geometry topics are covered in each grade?
K-2: identifying shapes and their properties. Grades 3-5: area, perimeter, angles. Grades 6-8: coordinate geometry, transformations, volume. Grades 9-12: proofs, trigonometry, circles.
