# Maths Year 2 Autumn Shape and Data (A)

Each unit has everything you need to teach a set of related skills and concepts. 'Teaching for Understanding' provides whole-class teaching and fully differentiated adult-led group activities. ‘Problem-solving and Reasoning’ develops these skills, and includes questions to enable you to assess mastery. Practice sheets ensure procedural fluency. Extra support activities enable targeted work with children who are well below ARE.

‘UNIT PLAN’ gives you a text version of all parts of the unit to use in your school planning documentation. ‘DOWNLOAD ALL FILES’ gives you that unit plan plus all of associated documents. These bulk downloads are added value for Hamilton Friends and School Subscribers.

## Unit 1 Left, right, clockwise, anti-clockwise turns (suggested as 2 days)

### Objectives

Understand left, right, clockwise and anti-clockwise as turns
Unit 1: ID# 2621

National Curriculum
P&D (ii)

Hamilton Objectives
37. Use mathematical vocabulary to describe position, direction and movement, including movement in a straight line.
38. Distinguish between rotation as a turn and in terms of right angles for quarter, half & three-quarter turns (clockwise & anti-clockwise).

### Teaching and Group Activities for Understanding

Day 1 Teaching
Display the resource sheet showing shelves of objects. Ask questions using language of position and direction, like: What object is on a shelf below the car, and left of the dinosaur?
Then give instructions using ‘left’ and ‘right’ and numbers of steps to enable a child to get to the door.
Group Activities
-- Program a floor robot with directional instructions to reach a specified destination.
-- Give directional instructions for someone to follow to a specified end destination.

Day 2 Teaching
Ask children to pretend that they are standing in the middle of a huge clock. Instruct them to turn the same way that the clock hands turn. This is clockwise. Demonstrate ¼ and ½ turns. Also model turning anti-clockwise.
Group Activities
Use the in-depth problem-solving investigation ‘Cover the Camel’ from NRICH as today’s group activity.
Or, use these activities:
-- Describe the number and direction of quarter turns on a journey through a maze.
-- Make and describe whole, half and quarter turns and their directions, using a floor robot.

### You Will Need

• Range of objects or ‘Positional language’ sheet (see resources)
• Blindfold
• Floor robots such as Roamer
• Number cards for 3, 6, 9 & 12
• ‘How many quarter turns?’ and ‘Help the robot to get home’ sheets (see resources)
• Large blocks, Lego & Lego people

Day 2

### Procedural Fluency

Day 1
Help the robot to get home using directional language.

Day 2
Describe a route on a map using 1/4, 1/2 and whole turns.

### Mastery: Reasoning and Problem-Solving

• Draw a shelf. In the middle of the shelf, draw a ball. To the left of the ball, draw a teddy. To the right of the ball, draw a car.
• Look at a clock face.
Both hands are pointing straight up at the 12.
The big hand moves a quarter turn clockwise. Draw the new position of the hands.
From this position, the hour hand moves 2 quarter turns clockwise. Draw the new position of the hands.
• Would it have been the same if the hour hand had moved two quarter turns anti-clockwise?

In-depth Investigation: Cover the Camel
Can you cover the camel by rotating puzzle pieces a ¼ turn at a time? Cover the Camel from nrich.maths.org.

## Unit 2 Draw and describe 2-D shapes & polygons (suggested as 3 days)

### Objectives

Draw and describe 2-D shapes and polygons
Unit 2: ID# 2633

National Curriculum
PofS (i)

Hamilton Objectives
33. Identify/describe common 2-D shapes, referring to properties including on the surface of 3-D shapes; compare/sort 2-D shapes.
34. Recognise symmetry in a vertical line.

### Teaching and Group Activities for Understanding

Day 1 Teaching
Draw a range of different pentagons, hexagons and octagons on the IWB, making sure that you include irregular shapes. Draw out what is the same and different. Count numbers of sides. Look at whether shapes are symmetrical or not.
Group Activities
-- Sort shapes into hexagons, pentagons and octagons.
-- Make a variety of shapes using skipping ropes.

Day 2 Teaching
Hide a right-angled triangle behind a ‘wall’ (side of a box) so that the right angle appears first. Ask children to say what shape it might be. Discuss and reveal more. Finally reveal shape. Repeat with other 2-D shapes, drawing out properties from children.
Group Activities
-- Draw a range of different looking pentagons, hexagons and octagons.
-- Draw shapes with 5, 6 or 8 sides.

Day 3 Teaching
Ask children to imagine 2 squares drawn next to each other. Ask them to draw this. Identify the rectangle. Add another square. This could be another rectangle or could be a hexagon. Add more squares to create different polygons.
Group Activities
Use the ‘Cut and Paste’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Put squares, rectangles and triangles together to make new shapes.
-- Describe 2-D shapes in a feely bag through the number of sides and right angles they have.

### You Will Need

• ‘Match the shapes to the right set’ sheet (see resources)
• Set of 2-D shapes for each group of 5, e.g. square, rectangle, circle, triangle and oval
• 16+ skipping ropes
• Range of large 2-D shapes: regular & irregular
• A cardboard box & feely bag
• Dotty paper (see day 2 Practice sheet 1)
• Geoboards & elastic bands
• Dice with 5,5,6,6,8,8 on the faces
• Shapely Lines’ activity from nrich.maths.org

### Mental/Oral Maths Starters

Day 1
2-D shape (pre-requisite skills)

Day 2
Recognise 2-D shapes (pre-requisite skills)

Suggested for Day 3
Pattern (simmering skills)

### Procedural Fluency

Day 1
Identify shapes. Use colour to sort them into pentagons, hexagons and octagons.

Day 2
Draw different pentagons, hexagons and octagons.

Day 3
Create clues to identify shapes using descriptions of their properties.

### Mastery: Reasoning and Problem-Solving

• 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: Cut and Paste
Children use Escher’s method of creating tessellations from rectangles and regular triangles or hexagons. Using the language of 2-D shape and symmetry they describe the patterns created.

### Extra Support

Jig Shapes
Describe the shapes from a card so the rest of the group can work out what it is. Jig Shapes from nrich.maths.org

## Unit 3 Sort shapes: Venn and Carroll diagrams (suggested as 2 days)

Hamilton Objectives
33. Identify/describe common 2-D shapes, referring to properties; compare/sort 2-D shapes.
34. Recognise symmetry in a vertical line.

### Teaching and Group Activities for Understanding

Day 1 Teaching
Place 2 hoops on the floor, 1 labelled ‘straight lines’ and the other ‘curved lines’. We’re going to use these 2 sets to sort capital letters. Ask children to look at different letters and decide which set to place them in. Discuss what happens if a shape has both straight and curved lines. Overlap the hoops to create an intersection.

Group Activities
-- Sort the letters of a name into a Venn diagram using straight lines and curved lines for set headings.
-- Sort shapes into Venn diagrams according to differing properties.

Day 2 Teaching
Ask each child to draw a 4-sided shape on their whiteboards. Write 2 labels: ‘squares’; ‘not squares’ and place these on the floor. Children sort their shapes.
Then write 2 labels: ‘all sides the same length’ and ‘sides not all the same length’. Now sort the shapes on the Carroll diagram. Repeat, using different shape properties to sort.
Group Activities
Use the in-depth problem-solving investigation ‘Carroll Diagrams’ from NRICH as today’s group activity.
Or, use these activities:
-- Sort regular and irregular shapes into Carroll diagrams.
-- Suggest criteria for sorting an assortment of buttons into Carroll diagrams.
