2D and 3D Shapes
This topic covers 2 learning steps, guiding your child from the basics through to confident problem-solving. Each step includes a worked example and adaptive practice questions.
What Your Child Will Learn
- 2D Shape Names
Name basic 2D shapes - 3D Shape Names
Name basic 3D shapes
Common Mistakes
- Describing shapes only by appearance rather than properties (e.g. "it looks like a house" instead of "it has 5 sides")
Encourage mathematical language: count sides, count corners, check for right angles. "This shape has 4 sides and 4 right angles — it is a rectangle." - Thinking all shapes with 4 sides are rectangles
There are many quadrilaterals (four-sided shapes). A diamond, a parallelogram, and a trapezium all have 4 sides but are not rectangles. The key difference is whether the angles are right angles.
Tips for Parents
- Make shapes with lolly sticks or straws — how many different shapes can you make with 4 sticks? With 5?
- Explore symmetry: fold paper shapes in half. Do both halves match? Use mirrors to investigate symmetry.
- Go on a walk and photograph shapes in the environment — take a "shape safari" around your neighbourhood.
- Sort shapes together: "Put all the shapes with curved sides here, and all the shapes with only straight sides there."
Key Words
- Vertex (corner) — The point where two sides of a shape meet — a triangle has 3 vertices.
- Side — A straight or curved line forming part of a shape.
- Symmetry — When one half of a shape mirrors the other — like a butterfly.
- Right angle — A square corner — exactly 90 degrees, like the corner of a book.
- Quadrilateral — Any shape with exactly 4 straight sides.
Where This Fits
Before this topic: Children should name basic 2D and 3D shapes and identify simple properties like "has 3 sides."
After this topic: Shape properties lead to classifying quadrilaterals, understanding angles, and working with symmetry in Years 3-4.
How MathCraft Teaches This
In MathCraft, 2D and 3D Shapes is taught through the Algebra & Arithmetic adventure track. Your child follows guided lessons with friendly characters, works through examples step by step, then practises with questions that adapt to their level.
The adaptive engine tracks mastery across all 2 steps, revisiting concepts your child finds tricky and advancing when they're ready. Parents can see detailed progress in the Parent Dashboard.
