Place ValuePlace value cards, cubes and Base 10
apparatus to recognize values of numbers.
i.e. make the number 24
Step 1: separate the to its value
2 tens and 4 ones
Step 2: make that number with either
cubes or place value cards

Method25 + 33= 58Step 1: partition numbers ( tens 20 + 30) (ones 5 + 3)Step 2: add up the Tens ( 20 + 30 = 50)Step 3: add up the Ones ( 5 + 3 = 8)Step 4: add both ( 50 + 8 = 58)
55 + 26 (Tens 50 + 20 = 70) (Ones 5 + 6 = 11)70 + 11 = (Tens 70 + 10 = 80 ) (Ones 0+1=1)80 + 1 = 81

Using a Number LineAdding 5 + 3 = 8Step 1: start on the biggest number and count on in
jumps.
Subtracting 18 – 4 =Step 1: start on the biggest number and count back in
jumps.

Using a blank number line34 + 25 = 59
Step 1: partition 2nd number: 25 = 2 tens (20) and 5 ones (5) Step 2: jump the 10s ( 2 tens)Step 3: jump the ones ( 5)

Addition and Subtraction a with ‘number square’
Adding 1254 + 12 = 66Step 1 : Partition the number (one 10, two ones) 10 and 2Step 2: add on the 10 ( down 1)Step 3: add on the ones ( right 2)
Adding 10 go down 1Subtracting 10 up 1Adding 1go right 1Subtracting 1 go left 1

Addition and Subtraction a with ‘number square’Adding 9 :25 + 9 = 34Step 1: find 25 on number squareStep 2: simplify the calculation ( add 10 -1).To add 10 simple go down one then then take 1 to make 9 ( go left 1 space)
Down 1 left 1
Subtracting 9:25 -9 = 16Step 1: find 25 on the number gridStep 2: simplify the calculation ( take 10 +1)Step 3: to take ten go up 1 then take 1 by goingright 1.
Up 1 right 1

Multiplication in KS1First recognize that multiplication is repeated addition ? lots of how many per group total
3 x 5 = 15Is the same as 2 lots of 5 or 5 + 5 + 5 = 15Use pictorial cues to represent a ‘times’ calculation.Encourage them to write the calculation:
5 + 5 + 5 = 15
