Grade 3 · 2 pages · A4What each level generates
Grade 3 symmetry — the exact skill behind each difficulty setting, straight from the generator.
- Level 1Lines of symmetry in a shape
- Level 2Symmetry in capital letters
- Level 3A shape and a letter together
Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →
More Grade 3 geometry skills
Each one generates a different kind of question, with its own three levels and answer key.
- PerimeterAdd up every side to find the distance all the way around a shape.
- Area of RectanglesMultiply length by width to find the space a rectangle covers.
- 2D Shape PropertiesName a flat shape from its sides, corners and angles — and back again.
- 3D SolidsCount the faces, edges and corners of solid shapes, and name them.
Frequently asked questions
▸What geometry should a Grade 3 student know?
Grade 3 usually covers perimeter of rectangles and squares, and naming two-dimensional shapes from their sides, corners and angles. These worksheets do both on separate sheets — Perimeter and 2D Shape Properties — alongside Area of Rectangles, 3D Solids and Symmetry. Each sheet carries its own three levels, so the level control changes how hard that skill is rather than which skill you get.
▸How do you find the perimeter of a rectangle?
Add all four sides. Because opposite sides of a rectangle are equal, you can add the length and the width and then double the total: a 9 cm by 4 cm rectangle has a perimeter of 2 × (9 + 4) = 26 cm. The Rectangles level of Perimeter drills exactly that with small, friendly measurements.
▸Do these worksheets need diagrams or a ruler?
A diagram on some of them, and the sheet prints it for you. On Perimeter and Area of Rectangles the shape is drawn to scale at the lower levels, with the measurements written on it rather than in the sentence, because reading a length off a shape is part of the skill. The top level of each of those two turns the question round — it gives the perimeter or the area in words and asks for a side back, so there is nothing to draw. 2D Shape Properties and Symmetry draw the shape at level 1 and are in words above it. No ruler is needed: every number a question uses is printed. 3D Solids is written entirely in words at every level. Everything still prints in black and white on any printer.
▸How many questions should a Grade 3 geometry sheet have?
