Decimal Number Bonds to 1
Doubles and Halves
(Yr 4 = number bonds to 100)
(Yr 4 = doubles and halves to 100)
E.g.
1+0=1
0.99 + 0.01 = 1
0.98 + 0.02 = 1
AND
(Yr 4 = 7, 8, 9 times tables)
1–0=1
1 – 0.01 = 0.99
1 – 0.02 = 0.98
.
.
.
.
0.01 + 0.99 = 1
0+1=1
E.g.
0 x 12 = 0 AND
1 x 12 = 12
2 x 12 = 24
.
1 – 0.99 = 0.01
1–1=0
.
.
.
11 x 12 = 132
12 x 12 = 144
Decimal Number Bonds to 10
E.g.
10 + 0 = 10
9.99 + 0.01 = 10
9.98 + 0.02 = 10
AND
0 ÷ 12 = 0
12 ÷ 12 = 1
24 ÷ 12 = 2
.
.
.
132 ÷ 12 = 11
144 ÷ 12 = 12
10 – 0 = 10
10 – 0.01 = 9.99
10 – 0.02 = 9.98
.
.
.
.
0.01 + 9.99 = 10
0 + 10 = 10
All times tables to
12 x 12
Multiplying by 10000
(Yr 4= multiplying by 100)
The digits shift four places to the
left and 0 fills the empty columns
E.g.
27 x 10000 = 270000
When 27 in multiplied by 10000, the 2 tens
become 2 hundred thousands, the 7 units
become 7 ten thousands and there are 0
thousands, 0 hundreds, 0 tens and 0 units
Dividing by 10000
(Yr 4= dividing by 100)
The digits shift four places to the
right
E.g.
270000 ÷ 10000 = 27
.
10 – 9.99 = 0.01
10 – 10 = 0
When 270000 is divided by 10000, the 2
hundred thousands become 2 tens and the 7
ten thousands become 7 units
Say and read numbers to 100000

(Year 5)
Partition 5 digit numbers
(Yr 4 = partition 4 digit numbers)
E.g.
21537 = 2 ten thousands, 1 thousand, 5
hundreds, 3 tens and 7 units
= 20000 + 1000 + 500 + 30 +7
State what each digit
represents in numbers with
2 decimal places
E.g.
In the number 3.75, the 7 digit = 7
tenths and the 5 digit = 5 hundredths
Multiply a 2 digit number by a 1 digit number
(Yr 6 = multiply a 3 digit number by a 1 digit number)
27 x 4 = 20 x 4 + 7 x 4
= 80 + 28
= 108
