# Maths Year 2 Summer Fractions and Time

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

## Fractions of amounts; count in fractions(suggested as 2 days)

### Planning and Activities

Day 1 Teaching
Show 16 counters on the Interactive Whiteboard. Demonstrate how we can find 1/2 by sharing and then find 1/4 by halving a half. Display the sequence of ‘Design a flag’ images to model different ways to represent 1/2, then 1/4 of 24 squares.
Group Activities
-- Shade flag templates to show halves and quarters of amounts.

Day 2 Teaching
Show children 12 bricks in the centre of the circle. Write 1/4 of 12 and discuss how to find a quarter by sharing the bricks into 4 piles. Model sharing 15 bricks between 3 piles to find 1/3. Display a bar model (see resources) split into thirds. Discuss how this relates to sharing the bricks. Model finding 1/3 of 21. Repeat for 1/4 of 40, 3/4 of 40 and 2/3 of 12.
Group Activities
-- Find 1/3s and 1/4s of amounts, using bar models to represent whole and fraction parts.
-- Use an online game to practise calculating 1/4 and 3/4 of amounts.

Day 3 Teaching
Write 1/2 of □ = □. In pairs, children discuss what numbers might complete the sentence. Test ideas, using Interactive Whiteboard counters if required. Display 1/2 of 5 = 10. Now you be the teacher. Is this correct? Repeat with 1/4 of □ = □. Display 1/3 of 12 = 6. Is this correct? Repeat with 1/3 of □ = □.
Group Activities
-- In a game context, complete as many fraction number sentences as possible to show 1/2, 1/3 or 1/4 of amounts to 12 (or 20 or 30).

### You Will Need

• ‘Design a Flag’ sheets 1–6 (see resources)
• ‘Design your own flags’ sheets 1 and 2 (see resources)
• Coloured pencils and counters
• ‘Fractions: bar models’ (see resources)
• Additional activity sheets (see resources)
• Number cards or tiles: numbers 1 to 12 (and some to 20 or 30)
• ITP: Number Grid

### Mental/Oral Maths Starters

Day 1
Count on in 3s (pre-requisite skills)

Day 2
Understanding division as the inverse of multiplication (pre-requisite skills)

Suggested for Day 3
Equivalence (simmering skills)

### Worksheets

Day 1
Design a range of bookmarks based on given combinations of 1/2s and 1/4s.

Day 2
Complete bar models.
Use to calculate 1/4, and 1/3 of amounts.
Use to calculate unit and non-unit fractions of amounts.

Day 3
Calculate the missing numbers or fractions in number sentences finding fractions of amounts.

### Mastery: Reasoning and Problem-Solving

• Find 1/2 of each amount.
£24
£44
£60
Now find 1/4 of each amount.
• What is 1/3 of 30? Use this answer to find 1/3 of 60.
• Complete each sentence using the bar models to help.
3/4 of 24 = ☐
 24

2/3 of 18 = ☐

 18

3/4 of 44 = ☐

 44

In-depth Investigation
Use the Group activity from Day 1.
