Maths Overview

  1.  Shape monsters

Gather a selection of 3D shapes, including cylinders (crisp tubes, kitchen-roll centres), cuboids (toothpaste or teabag boxes) and triangular prisms (chocolate boxes).

Watch: https://www.bbc.co.uk/bitesize/topics/zjv39j6/articles/ztpwdmn

Discuss the properties of the objects, including the number of sides and corners. Ask the children to design a monster using the 3D shapes. If there is time, children could cover and decorate the surfaces of the shapes before they are joined together.

Cut out shapes from the Activity sheet , ‘2D shapes’. Encourage the children to think about 2D shapes that relate to different 3D parts of their monster – for example, cuboids have rectangular faces. Invent and sing a song, replacing the word for a 2D shape each time: Maths monster, maths monster, munch, munch, munch. Try this rectangle for your lunch!’

  1. Shape detectives

Watch: shape song https://www.bbc.co.uk/bitesize/clips/zhnvcdm

Explain that they are going have a go at being a ‘maths detective’.

Explain that the job of the maths detective is to try and work out which shape has stolen some sweets

Look at the sheet with a selection o of shapes on and ask questions about the shapes on the table. The other two players are only allowed to answer ‘yes’ or ‘no’.

Provide some examples of the sorts of questions you are looking for. For example:

  • Does the shape have straight sides?
  • Does the shape have a right angle?
  • Does the shape have any curved sides?
  • Does the shape have any corners/points?
  • Is it a packet used for something?

If the answer is ‘no’, the detective removes/crosses out/ covers up the shapes for which the answer would have been ‘yes’. If the answer is ‘yes’, the detective removes all the shapes for which the answer would have been ‘no’.

You will need to work with children to improve the types of questions they ask and the vocabulary used. Finally, the detective should narrow down the choices and then attempt to name the shape that has stolen the sweets.

3. Shape sorter

Cut out the shapes from the Activity sheet , ‘2D shapes’.  Ask children to suggest different ways that the shapes could be grouped and sorted. Show children the sorting table on the Activity sheet , ‘Shape sorting’. Explain that it is called a Carroll diagram – named after Lewis Carroll, author of Alice’s Adventures in Wonderland. Which shapes belong in which column? Ask the children to complete the table by sticking shapes into each column.

Now, show children the more complicated sorting table. Demonstrate where a couple of the shapes should be placed, then ask children to complete the diagram by sticking in the shapes.

Ask the children to complete the third sorting table, showing symmetrical and non-symmetrical triangles, on their own.

4. Treasure hunt

Point out that many everyday things are common shapes such as circles, square rectangles, oblong rectangles, and triangles. Look for some examples in the classroom/home – for example, floor tiles, the clock or windows. Next, take the children on a ‘shape walk’ in and around school and encourage them to spot different shapes.

 

Watch:  https://www.bbc.co.uk/teach/skillswise/2D-shapes/zvd4scw

Ask children to draw what they have seen/found Activity sheet , ‘Shapes treasure hunt’. You could take digital photographs of the shapes that can then be printed and compiled into shape books.

 

 

5, Sweet Shapes

Use the Activity Sheet- ‘Sweet Shapes’ to identify and count up the shapes in the house.  Can you name the shapes and escribe their properties using language:

Sides

Corners/ angles

Do any have a right angle?

Challenge: describe the properties of each shape e.g. a square has 4 equal sides and fur corners that are right angles.

6. Shape Up (Y2)

Shapes can make beautiful patterns.  Look at wrapping paper, wallpaper and in books to see different patterns.  Can you complete the pattern challenges using the Activity Sheet- ‘Shape Up’.
