Y2: Add and subtract 2-digit numbers.

National Curriculum
Y1: Add-Sub (i) (iii); Meas (iii)
Y2: PV (i) (ii); Add-Sub (i) (ii)

Y1 Hamilton objectives
22. Recognise and know the value of different denominations of coins and notes.
11. Add small numbers by counting on and subtract small numbers by counting back.
3. Count on and back in 10s from any 1-digit or 2-digit number, e.g. 23, 33, 43, 53... Continue to just over 10.

Y2 Hamilton objectives
6. Use place value and number facts to solve problems, e.g. 60 –  = 20.
10. Add a 2-digit number and 10s; add two 2-digit numbers that total less than 100 by counting on in 10s and 1s.
11. Count back in 1s or 10s or use number facts to take away, e.g. 27-3 = or 54-20 =.

### Planning and Activities

Day 1
Show children large mock coins (or use the IWB): 10p, 5p, £1, 2p and 1p, out of order of value. Place the coins in order along a line, discussing each one. Find the numbers of pennies that can be swapped for each coin.
Further Teaching with Y2
Use Spider to work out 33 + 21 and 42 + 25.
Group Activities: T with Y2
Y1 -- Play a game involving collecting and exchanging coins.
Y2 -- Adding 2-digit numbers using Spider. Use Spider to add 22 to 2-digit numbers.

Day 2
Demonstrate adding 2 or 3 coins up to 10, e.g. adding 2p by tapping it twice and saying five, six.
Further Teaching with Y2
Model partitioning to add 34 + 23. Use the same method as for doubling and record in same way. Repeat for 45 + 24 and 36 + 22.
Group Activities: T with Y2
Y1 -- Write coin addition number sentences; find different totals.
Y2 -- Add two 2-digit numbers card game: collaborative calculations.

Day 3
Share different ways of making 7p using 5p, 2p and 1p coins. Demonstrate making an ordered list to find all possibilities. Record the additions at the side and show how we now know we have found them all.
Further Teaching with Y2
Use partitioning to add pairs of 2-digit numbers, where 1s come to more than 10.
Group Activities: T with Y2
Y1 could use the ‘Coins in my pockets’ in-depth problem-solving investigation below; Y2 could use the ‘Lines of Numbers’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
Y1 -- Investigate how many ways children can make 6p and 8p.
Y2 -- Choose cards to make 2-digit numbers, then find the total using partitioning. Suggest pairs of numbers that make a given total.

Day 4
Use the 100-bead bar then Spider counting on the 1 to 100 grid to count in 10s from single-digit numbers.
Further Teaching with Y2
Show a 1 to 100 grid. Use Spider and Fly to work out 54 – 23, 86 – 32 and 77 – 25.
Group Activities: T with Y2
Y1 -- Investigate possible missing numbers in the number sentence □ is 10 more than □.
Y2 -- Subtract 2-digit numbers using a 1 to 100 grid and Spider and Fly. Find mystery subtraction numbers following the movements of Spider and Fly.

Day 5
Revisit subtracting 10s and 1s with Y1 and Y2.
Further Teaching with Y1
Use Spider on the 1 to 100 grid to support counting back in 10s. Find 10 less than given numbers, both on the grid and on a beaded line.
Group Activities: T with Y1
Y1 -- Throw a beanbag onto a 100 grid and find 10 more/less. Create a 2-digit number and find 10 less. Record as a number sentence.
Y2 -- Solve subtraction word problems
