Early Years

 Target Example Can your child answer these? Say numbers in order (up to 10) How many marbles are in this jar? Say 1 more than a number (up to 100) 1 more than 4 is 5. There are seven marbles in this jar. If I put one more in, how many are there? Say 1 less than a number (up to 10) 1 less than 8 is 7. There are ten beads in the pot. If I take one out, how many are left? Count on from any number (up to 10) Start at 5. Count on until you reach 10. Say numbers in order (up to 20) How many marbles are in this pot?

Year 1

 Target Example Can your child answer these? To know all number bonds to 10 by heart. 0 + 10 = 10 1 + 9 = 10 2 + 8 = 10 What do I need to add to 7 to make 10? Use number cards 0-9 – can you pair these to make 10? To recall addition facts to 5. 0 + 1 = 1 0 + 3 = 3 4 + 1 = 5 2 + 3 = 5 Which numbers make 4? How many ways can you think of to make 5? To recall subtraction facts 5 4 – 1 = 3 3 – 2 = 1 5 – 4 = 1 Using 5 beans, hide some under a beaker. How many are there left? What is the subtraction I just performed? To count on in 2s, 5s and 10s. Complete the sequence 2, 4, 6, 8, 10, __, __ How far can you count in 2s? 5s? 10s? 90, 80, 70, __, __ To recall doubles up to double 10. Double 2 is 4. Double 6 is 12. Double 8 is 16. Roll a dice – what is double that amount? I doubled a number and got 18. What was my number?

Year 2

 Target Example Can your child answer these? To know all number bonds to 20 by heart. 0 + 20 = 20 1 + 19 = 20 2 + 18 = 20 3 + 17 = 20 How many pairs of numbers do you know which make 20? How many more must I add to 16 to make 20? To know which multiples of 10 combine to make 100. 0 + 100 = 100 10 + 90 = 100 20 + 80 = 100 Look at these multiples of 10. Which go together to make 100? 10  20  30  40  50  60 70 To recall all doubles up to double 20. 1 + 1 = 2 2 + 2 = 4 up to 19 + 19 = 38 20 + 20 = 40 What is double 8? 11? 14?   Roll two numbers on a dice and then double it. To derive halves from corresponding doubles. Half of 2 is 1. Half of 10 is 5. I started with a number, I halved it and got 12. What did I start with? To quickly recall multiplication facts for 2, 5 and 10 times tables. 0 x 2 = 0 3 x 5 = 15 6 x 10 = 60 What is 3 x 2? 5 x 10? 2 x 6? To derive corresponding division facts for 2, 5 and 10 times tables. 20 ÷ 5 = 4 22 ÷ 11 = 2 50 ÷ 10 = 5 What is 40 ÷ 5? 18 ÷ 2? 70 ÷ 10?

Year 3

 Target Example Can your child answer these? To know all sums and differences for multiples of 10 up to 100. 70 + 80 = 150 60 – 40 = 20 60 + 30 = 90 40 – 30 = 10 Add 80 and 30. Tell me how you did it? Tell me all of the pairs of 10s which make 90. To know by heart pairs of numbers which make 100. 51 + 49 = 100 75 + 25 = 100 63 + 37 = 100 What must you add to 62 to make 100? How much change would I get from £1 if I spent 69p? To know multiplication facts for the 3, 4, 6 and 8 times table. 0 x 4 = 0 11 x 3 = 33 8 x 4 = 32 What is the number before 56 in the 8 times table? What is 7 X 4? To recall division facts for 3, 4, 6 and 8 times table. 36 ÷ 6 18 ÷ 3 16 ÷ 4 What is 36 ÷ 6? What is 72 ÷ 8? To recognise multiples of 2, 5 and 10 up to 1000. 24 is a multiple of 2. 35 is a multiple of 5. 650 is a multiple of 2, 5 and 10.

Year 4

 Target Example Can your child answer these? To double any 2-digit number. Double 26 = 52 Double 97 = 194 What is the missing number 17, 34, __,136. I think of a number and half it, I get 55. What did I start with? To halve any even 2-digit number. Half of 48 = 24 Half of 72 = 36 Half of 90 = 45 Which numbers are missing in this sequence. 96, __, 24, __, 6 To know multiplication facts for the 7, 9, 11 and 12 times table. 0 x 7 = 0 1 x 11 = 11 9 x 3 = 27 12 x 4 = 48 What is the number before 56 in the 7 times table? What is missing - 9, 18, 27, __, 45, 54, __ To know division facts for the 7, 9, 11 and 12 times table. 77 ÷ 7 = 11 45 ÷ 9 = 5 60 ÷ 12 = 5 What is the answer to 14 ÷ 7? What is the answer to 44 ÷ 11?
