1 For more information - Begin recognition in EYFS Age related expectation at Y1 (secure use of language) shape, flat, curved, straight, round, hollow, solid, vertexvertices (not corner), side, end, bigger, larger, smaller, size Recognise and name common 2d shapes (these should be as flat as possible, children will also need to experience many irregular shapes) Rectangle (including square), circle and triangle, pentagon, hexagon, octagon Different orientations count sides (straight/ curved) to identify name. Triangles always have 3 sides Rectangles and squares always have 4 sides Polygons are any 2d shape which have at least 3 straight sides and three angles. They can be regular and irregular. Most are irregular. Recognise and name common 3d shapes. Cuboid (including cube), pyramid, sphere, cone, cylinder Different orientations count faces (curved/flat) and vertices Cuboids are 3d shapes with rectangular faces. Pyramids are solid shapes which have a polygon as one face, other faces meet at one opposite apex. They can be regular and irregular. Describe movement Whole, half, quarter, and three quarter turns

2 Age related expectation at Y2 For children to be using (as previous) Surface, line of symmetry, symmetrical, mirror line, reflection, base, squarebased, As Y1 and: Identify and describe the properties of 2d shapes, including the number of sides (equal sides) and line symmetry in a vertical line. Sort shapes in Venn diagrams As Y1 and: Identify 2d shapes on the surface of 3d shapes (circle on a cylinder, triangle on a pyramid) Identify and describe the properties of 3d shapes including the number of faces, edges and vertices. Sort shapes in Venn diagrams As Y1 and: Use mathematical vocabulary to describe movement, including rotation as a turn. Understand the link between rotation and turns in terms of right-angles for quarter, half and three quarter turns (clockwise and anti-clock wise) straight line. Vocab: two dimensional (2d length width or breadth), circular, triangular, rectangular, quadrilateral, polygon. A quadrilateral is a polygon with 4 straight sides and 4 angles (vertices). Most are irregular identify by counting sides. Vocab: three dimensional (3d length, width or breadth and height), prism A prism has flat sides and has the same cross section along its length. The cross-section will always be a polygon. There are no curved faces in a prism. A prism is named after its base (triangular based prism) A cuboid/cube is also a prism. A half turn makes a straight line.

3 Age related expectation at Y3 For children to be using (as previous) Right-angled, regular, irregular, parallel, perpendicular As Y2 and: Draw 2d shapes and describe them. Identify horizontal and vertical lines and pairs of perpendicular (at right angles) and parallel lines/sides (equal distance apart). As Y2 and: Make 3d shapes using clixi plastic polygons. Recognise 3d shapes in different orientations and describe them. faces, edges and vertices. Recognise angles as a property of shape or description of a turn. Identify right-angles, recognise that two right angles make a half turn, three makes three quarters of a turn and four a complete turn. Identify whether angles are greater than or less than a right angle. Vocab: semi-circle, pentagonal, hexagonal, octagonal, parallelogram, rhombus, trapezium. Parallelograms are special types of quadrilaterals. A rhombus is also a parallelogram. A square is a quadrilateral, a parallelogram, a rectangle and a rhombus. Many shapes have several names according to their properties (see properties sheet) Vocab: hemisphere (half a sphere), Spheres and hemispheres are nonpolyhedron (not all faces are polygons).

4 Age related expectation at Y4 For children to be using Line, net, angle, concave, convex, open, closed, line symmetry Use Venn and Caroll diagrams for sorting Compare and classify 2d geometric shapes, including quadrilaterals and triangles, based on their properties (sides and angles) and sizes. Vocab: equilateral, isosceles, scalene triangles, heptagon, kite Identify lines of symmetry in 2d shapes presented in different orientations. Complete a simple symmetric figure with respect to a specific line of symmetry. Continue to identify horizontal and vertical lines and pairs of perpendicular (at right angles) and parallel lines/sides. Compare and classify 3d geometric shapes, based on their properties (faces, edges and vertices) and sizes. Introduce nets. Investigate nets of boxes. Introduce perpendicular and parallel faces. A triangular pyramid is also a tetrahedron (4 faces) Vocab: polyhedron (pl - polyhedra) spherical, cylindrical, tetrahedron, Polyhedron (many faces) are 3d shapes with polygons as faces. They are named after the number of faces. Identify acute and obtuse angles and compare and order angles up to 2 right angles by size. (use set squares, known right angles to compare) Know the sum of the angles of a triangle are 180 Look at angles in different orientations. Vocab: degree, acute, obtuse, ruler, set squares, angle measurer (protractor) These are all pairs of parallel lines

5 Age related expectation at Y5 For children to be using Congruent (same shape and size), similar (same shape, not size), axis of symmetry, reflective symmetry, diagonals (intersect/ bisect) No new 2d shapes. Distinguish between regular and irregular polygons based on reasoning about equal sides and angles. Use the properties of rectangles to deduce related facts and find missing lengths and angles. Investigate the diagonals of quadrilaterals (intersect, bisect) Recognise the properties of an octahedron (pl - octahedra)-8 faces, dodecahedron, 12 faces. Identify 3d shapes, including cubes and other cuboids from 2d representations Continue to visualise nets. Know angles are measured in degrees: estimate and compare acute, obtuse and reflex angles. Use a protractor to draw given angles, and measure them in degrees. Identify: - angles at a point and one whole turn (360 ) - angles at a point on a straight line and ½ a turn (total 180 ) - other multiples of 90

6 Age related expectation at Y6 For children to be using Circumference (distance around edge of circle), radius (distance from side to centre of circle), diameter (distance from side to opposite side through centre), concentric (equal distance from centre) arc, intersecting (diagonals crossing), bisect (cut in half) intersection (where they cross) plane (2d) Introduce circles. Compare and classify 2d shapes based on their properties (sides/ angles/ diagonals) and sizes. Draw 2d shapes using given dimensions and angles. Illustrate and name parts of circles, including: radius, diameter, and circumference and know that the diameter is twice the radius. Recognise, describe and build simple 3d shapes, including making nets. Recognise where angles meet at a point, are on a straight line, or are vertically opposite, and find missing angles. Find unknown angles in any triangles, quadrilaterals and regular polygons.
