Shape                                       Year    1     2     3     4     5     6

Year 1 - Recognise and classify familiar two dimensional shapes and three-dimensional objects using obvious features. <back to top>

2D and 3D Shapes

A great explanation and selection of activities explaining the properties of 2d and 3d shapes.

Closed/Open Shape Shoot

Can you tell the difference between an open and a closed shape? Six games to complete.

Four Piece Tangram

Recognise and manipulate familiar shapes to fill the design.

Polygon Shape Shoot

Polygon or not a polygon? How do you know? Six levels to help you 'get' this idea.

Shape Lab

Help Pablo finish his invention by handing him the right shape. Three levels beginning with 2D shapes and advancing to 3D shapes.

Shape Planet

Click on the the name of the part hidden 3D shape. Doesn't take long but is worth it just to hear the lady speak.

Shape Store

Create a picture with shapes. Drag the correct shapes onto the picture and make it move. Many Levels.

Sort Triangles

Can you sort the shapes into two groups: triangles and other shapes?

Year 2 - Describe and draw two-dimensional shapes, with and without digital technologies. Describe the features of three dimensional objects. <back to top>

2D Shapes - BBC

Help Dick and Dom recognise 2D shapes. Takes a while to load but is great fun! Four games.

Shape Maker HERE for MOBILE

Build, print and save pictures made of 12 different 2D shapes or see how fast you can build a shape using the online geoboard!

Can’t Wait to Tessellate

Learn about what 'tessellate' means and test what shapes tessellate by making a picture.

Polygon Playground

Drag all sorts of polygons to make thousands of shape pictures.

Shapes in Space

A space game where you can revise the properties of 2D and 3D shapes and blast the shapes when you get them right! Loads of levels.

Shape Invaders HERE for MOBILE

Shape Invaders bombard the Earth with imposter shapes. Hexagon Man's job is to destroy the imposter shapes. If the message is 'Save the Cubes', blast all shapes that are not cubes. Lots of levels.

Shape Shoot

Shoot shapes according to their name and features. Four levels to explore. Blast away!

Sort the 2D Shapes

Sort the shapes depending on whether they have no right angles, some right angles or all right angles.

Sort the Shapes

Sort basic shapes on a simple attributes diagram.

Tangram Game

Use the 7 shapes from a tangram to make a whole stack of great pictures. There are hints to help you!

Tangram Puzzles

Cover the shape with the tangram blocks so there is no gaps. Fortunetly there's a 'Hint' button!

Under the Sea

Can you tell how many vertices (corners) and sides are on these 2D and 3D shapes?

Year 3 - Make models of three dimensional objects and describe key features. <back to top>

3D Shapes - BBC

Use your knowledge of 3D shapes to collect biorods and prevent the evil Roboids from taking over the earth. Takes a while to load but has great graphics!

Calamity's Quest

Can you to solve the mathematical problems involving shapes, symmetry and position to help Captain Calamity rescue Princess Amber?

Geometric Solids

This tool allows you to learn about geometric solids and their nets. You can manipulate and color each shape to explore the number of faces, edges and vertices.

Interactive Tangram

An advanced tangram game that has lots of pictures to make. The 'hint' button is a little cranky.

Similair and Congruent Shape Shoot

So that’s what 'similar' and 'congruent' shapes mean! 6 levels.

Symmetry Sort

A symmetry matching game against the clock. Can you spot the symmetrical shapes?


Create your own tessellating shape by moving the edges of a shape then choose the colours for the repeated pattern.

Tessellation Tiles

A tool to show how shapes or combinations of shapes tesselate. Basic shapes can be dragged, rotated and coloured.

Year 4 - Compare the areas of regular and irregular shapes by informal means. Compare and describe two dimensional shapes that result from combining and splitting common shapes, with and without the use of digital technologies. <back to top>

Quadrilateral Shape Shoot

There's 6 types of quadrilaterals to shoot. Loads of levels to work through but you have to know your parallelogram from your rectangle…

Shape Class

Look at the shapes as they go past. Can you drag them into the right groups?

U Fix It with Ziff

Use measurement to help Ziff fix up his house. Look at 2D shapes and recreate them using a lazer cutter. Quite a challenge!

Year 5 - Connect three-dimensional objects with their nets and other two-dimensional representations. <back to top>

Triangle/Angle Shoot

Three games to choose from. Shoot the right type of angle or triangle. Loads of fun but you have to know your shape words. Three levels.

Airlines Builder

Dr. Marbles is building a new cyber ship but he needs your help. Use your knowledge of area and perimeter to help him launch it.

3D Paper Models and Nets

A site full of amazing nets to print out and make. There are some incredible shapes. The soccer ball is amazing! Good for Christmas stars too.

3D Shapes - BBC

An activity not a game. A really good revision of 3D shapes and their nets.

Year 6 - Construct simple prisms and pyramids. <back to top>

Isometric Drawing Tool

Draw figures using edges, faces, or cubes. You can shift, rotate, color and view in 2D or 3D. Lots of fun build stuff.

3D Paper Models/Nets

A site full of amazing nets to print out and make. There are some incredible shapes. The soccer ball is amazing! Good for Christmas stars too.
