Year 1 2-D and 3-D Shapes: summary and key words
Part of the Year 1 2-d and 3-d shapes chapter. Chapter overview · whole chapter on one page
Chapter summary
| Skill | Method |
|---|---|
| Name flat shapes | Count the straight sides and corners, then name the shape. A circle has no corners. |
| Big, small and turned | Size and turning do not change the name. Count the sides to check. |
| Name solid shapes | Count the flat faces and corners. A cube has 6 faces and 8 corners. A pyramid has 5 faces. |
| Curved solids | A sphere is round, a cone has a point, and a cylinder has 2 flat round faces. |
| Sort shapes | Choose one rule. Put each shape in the group that fits the rule. |
| Patterns | Find the part that repeats, then copy it on to the gap. |
