Pre-requisite skills – to use this starter, drag this slide to the start of Day 1
Show 10 pegs (e.g. 5 red and 5 blue) on a coat hanger. How can we split 10 into 2 groups? Record suggestions in an ordered list: 10 = 9 + 1, 10 = 8 + 2, etc. Are there any more? Show 8 and 2. Turn the coat hanger round to show Turn the pegs back to show again and then remove the last 2 pegs. What number sentence could we write? Record 10 – 2 = 8. Put the 2 pegs back on. Point to the 8 pegs. What if I took these off instead? What number sentence could we write? Repeat with 6 and 4, creating 10 – 4 and 10 – 6

Give each child a few 1p, 2p and 5p coins. Use your coins to make 4p. Can you make 7p with your coins? Who can count their coins to show me that they have exactly 7p? How many coins have you used? Quickly change your money to show me 9p. Who can count their coins to show me that they have exactly 9p?

Use the 100-bead bar to support counting on in 10s from 10 to 100 and back to zero. Point to various multiples of 10 and ask questions such as: What is 70 add 10? What is 10 more than 30? Do we need to move the beads across one at a time? What is 50 take away 10? What is 10 less than 90?

Day 1: Find totals to 20p.
12p
Who remembered
= 20?
Let’s count on the line to check…
Let’s use our 0-20p penny line!
How many hops was that?
We’ve marked 12p.
How many more pennies do I have to find to make 20p?
Is there a number fact that can help me with this problem?
Count the extra pennies to check!
12p + 8p = 20p

8. Day 1: Find totals to 20p. 15p Who remembered 15 + 5 = 20?
Let’s count on the line to check…
How many pennies have been marked this time?
How many more pennies do I need to make 20p now?
How many hops was that?
Children can now go on to do differentiated GROUP ACTIVITIES. You can find Hamilton’s group activities in this unit’s TEACHING AND GROUP ACTIVITIES download.
WT: Pick a money card and find the complement to 20p.
ARE: Listen to 1p coins dropping into a tin; work out the complement to 20p.
GD: Listen to 1p or 2p coins dropping into a tin; work out the complement to 20p.
15p + 5p = 20p
Count the extra pennies to check!

9. Year 1 The Practice Sheet on this slide is suitable for most children.
Differentiated PRACTICE WORKSHEETS are available on Hamilton’s website in this unit’s PROCEDURAL FLUENCY box.
WT: Make the amounts up to 20p Sheet 1. Use pennies to count out the same amount that they see in the purses, then they count up adding pennies until they get to 20p.
ARE: Make the amounts up to 20p Sheet 1. Use a 0-20p line (see resources) to check.
GD: Make the amounts up to 20p Sheet 2. Draw the coins you would use to make a total of 20p. Complete the number sentence. Challenge children to make up some of the amounts to 30p.

Day 2: Find totals using number facts.
Look at the toys and choose two to buy.
Add the amounts together.
Encourage children to use number facts that they know, e.g. doubles, number bonds to 10 or 20, or counting on from the larger number.
Children write a number sentence on their whiteboards.
Choose children to share their addition sentences;
scribe them on the board.
Ask children to explain the number facts they have used to find totals.
Today would be a great day to use a problem-solving investigation – Dicey Coins – as the group activity, which you can find in this unit’s IN-DEPTH INVESTIGATION box on Hamilton’s website.
Alternatively, children can now go on to do differentiated GROUP ACTIVITIES. You can find Hamilton’s group activities in this unit’s TEACHING AND GROUP ACTIVITIES download.
WT: As ARE but with prices lower than 10p.
ARE: Pretend-shopping: add two or three amounts, identifying helpful number facts where possible.
GD: Target totals using the ‘At the toyshop’ resource sheet.

What happens when it gets to 100p?
Let’s check…
Let’s check…
60p + 10p = 70p.
20p + 10p = 30p.
Find 20p + 10p
Do we need to count on in ones? What should we mark on the penny line?
We’ve marked 60p.
What is 60p add 10p?
Do we need to count on in ones…Who can remember Spider counting on the 100-square?
When we are adding 10 we do not need to count on all the numbers in between!
What have we done?

First mark on 42p.
Then jump two 10s!
42p + 20p = 62p

22. Problem solving and reasoning questions
Write the missing numbers.
12p = 20p
6p = 20p
13p + 3p + = 20p
Add the amounts to write the missing numbers in the table.
14p 6p 9p
Choose two amounts and add them. Choose a different two and add them. Choose another two amounts and add them.
Add 20p to each price:
30p p p
How much was added to 40p to get 70p?
Year 1

23. Problem solving and reasoning questions: Answers
Write the missing numbers.
12p + 8p = 20p
6p p = 20p
13p + 3p + 4p = 20p
Add the amounts to write the missing numbers in the table.
14p 6p 9p
Choose two amounts and add them. Choose a different two and add them. Choose another two amounts and add them. 14p + 6p = 20p, 14p + 9p = 23p and 9p + 6p = 15p are all possible additions.
Add 20p to each price:
30p 50p p 70p 80p £1 (or 100p).
How much was added to 40p to get 70p? 30p – an answer of 110p suggests a misreading of the question.
