# Maths Year 1/2 Summer Shape, Time and Data

Each unit has everything you need to teach a set of related skills and concepts.

## Exploring shape properties(suggested as 3 days)

### Planning and Activities

Day 1
Explain that a tangram is an ancient Chinese puzzle made from seven 2-D shapes. Give each pair of children a set, ask them to cut them up and then mix them up.
1. Try to rearrange them as a square…
2. Recreate a displayed outline picture of a dog.
Group Activities:
Y1/Y2 -- Whole class activity: Children use tangram pieces to recreate pictures.

Day 2
Show a selection of 3-D shapes, discuss shapes of faces, and count the number of edges. Show a film clip of cubes and cuboids in a kitchen.
Group Activities: T with Y1 or Y2
Y1 /Y2 -- ‘Shape competition’ – which shape has the most faces and which has the most vertices? (Y2: and edges).

Day 3
Show a film clip to introduce the concept of nets. Show three nets, discussing which could make a cube. Show a tetrahedron made from a net; name and count its faces.
Group Activities: T with Y1 or Y2
Y1 /Y2 -- Investigate which nets will fold to make a complete cube and a tetrahedron.

### You Will Need

• ‘Tangram dog’ (see resources)
• Online tangrams game
• ‘4-piece Tangram’ (see resources)
• ‘4-piece Tangram pictures’ (see resources)
• ‘4-piece Tangram answers’ (see resources)
• ‘7-piece Tangram pictures’ (see resources)
• ‘7-piece Tangram answers’ (see resources)
• 3-D shapes, including tetrahedra
• Baked bean tin (or other cylindrical tin)
• Ball/globe; Cereal packet
• Coloured stickers; Sticky tack; Sticky notes
• ‘Nets’ Sheets 1–9 (see resources)
• Scissors; Sticky tape

### Short Mental Workouts

Day 1
Properties of 2-D shapes

Day 2
Guess the 2-D shape

Day 3
Properties of 3-D shapes

### Worksheets

Day 1
Y1/Y2: There is no worksheet for Day 1. Use Group Activity resources.

Day 2
Y1: Match 2-D faces to 3-D shapes.
Y2: Count faces and vertices of 3-D shapes.

Day 3
Y1/Y2: Identify which nets will make cubes/tetrahedra.

### Mastery: Reasoning and Problem-Solving

Y1

Imagine it turns through half a complete turn. Draw what it looks like now.
• Find an example of each of these shapes in your classroom and draw it.
1. Cylinder
2. Cube
3. Cone
4. Sphere
• What shape is a cereal box? How many edges does it have?

Y2
This unit has no separate problem-solving activities for Y2.

Y1/Y2 In-depth Investigation
Use the Group Activity from Day 1

### Extra Support

Y1/ Y2: Behind the Wall
