## Unit 1 2-D shapes (suggested as 3 days)

### Objectives

2-D shapes
Unit 1: ID# 12618

Y1: 2-D shape
Y2: 2-D shape

National Curriculum
Y1: PofS (i)
Y2: PofS (i) (iv)

Y1 Hamilton objectives
24. Name and describe common 2-D shapes; recognise the difference between 2-D and 3-D shapes.
23. Sort items into lists or tables.

Y2 Hamilton objectives
33. Identify/ describe common 2-D shapes, referring to properties; compare/sort 2-D shapes.

### Planning and Activities

Day 1
Children close their eyes while you put a shape in a feely bag. Describe it. Children work in pairs to pick up a shape like the one you are describing. Describe and name different pentagons, hexagons and octagons.
Further Teaching with Y2
Display, discuss and note similarities in the ‘family’ of regular shapes, e.g. heptagon, octagon, nonagon and decagon.
Group Activities: T with Y1 or Y2
Y1 -- Make gummed shape pictures and describe the properties of the shapes that are used.
Y2 -- Sort shapes into hexagons, pentagons and octagons. Some children will explore making shapes using skipping ropes.

Day 2
Spot shapes around the classroom. Then slide shapes slowly behind a ‘wall’, children guess what shapes they are, also discussing what shapes they cannot be.
Group Activities: T with Y1 or Y2
Use the in-depth problem-solving investigation ‘Shape wheels’ as today’s group activity.
Or, use these activities:
Y1 -- Describe shapes to a partner then draw the shapes on whiteboards.
Y2 -- Draw a range of different pentagons, hexagons and octagons. Some children will put squares, rectangles and triangles together to create new shapes.

Day 3
Draw a range of squares, triangle, circles and rectangles of different proportions and orientations. Sort them into squares, triangles, circles and rectangles.
Further Teaching with Y2
Sort 4-sided shapes in Carroll diagrams.
Group Activities: T with Y2
Y1 – Sort and/or describe 2-D shapes according to given criteria.
Y2 -- Sort regular and irregular shapes into Carroll diagrams.

No straight sides.
3 sides, all straight.
4 sides where 2 are longer than the other 2.
• Copy this table:
 all straight sides 1 or more curved sides
• Identify 'flat' objects around the class, e.g. the clock face. Draw them in the table in the correct column.

Y2

• Draw 3 differently-shaped irregular hexagons. Draw another that has one line of symmetry.
• True or false?
All hexagons have straight sides.
A pentagon is always house-shaped.
Any shape with 4 sides and 4 right angles is a type of rectangle.
A hexagon could have 4 right angles.

In-depth investigation: Shape wheels
Children make a sequence of coloured shapes, changing one attribute at a time so that the sequence can end where it started, so forming a circular sequence.
