Know by heart all
addition and
subtraction facts for
each number to at
least 10
Eg the number 4
0+4=4
Now you try for the
number 5:
Know by heart…..all addition and
subtraction facts for each number to 20.
18
1+17=18 18 – 17 = 1
2 + 16 = 18 18 – 16 = 2
1+3=4
2+2= 4
3+1=4
Then apply the ‘If I
know, I also know’
rule for each of these
addition statements.
If I know 4 - 3 = 1
I also know
4-1= 3
3+1= 4
1+3=4
5 + 95 = 100
95 + 5 = 100
15 + 85 = 100
85 + 15 = 100
25 + 75 = 100
75 + 25 = 100
35 + 65 = 100
65 + 35 = 100
45 + 55 = 100
55 + 45 = 100
Learn the above facts and write the corresponding subtraction calculation for each.
1 + 3 = 4
Now you write the rest of the facts.
Now you try
for the

Eg the number 7
0 + 7 = 7
1 + 6 = 7
2 + 5 = 7
3 + 4 = 7
4 + 3 = 7
5 + 2 = 7
6 + 1 = 7

Now you try for the
number 6:
Know by heart…..all addition and
subtraction facts for each number to 20.
19
1+18=19
19 – 18 = 1
2 + 17 = 19 19 – 17 = 2
Then apply the ‘If I
know, I also know’ rule
for each of these
addition statements.
If I know
3 + 4 = 7
I also know
4 + 3 = 7
7 - 4 = 3
7 - 3 = 4

3 + 5 = 8
4 + 4 = 8
5 + 3 = 8
6 + 2 = 8
7 + 1 = 8
8 + 0 = 8
Then apply the ‘If I

for each of these
addition statements.
If I know

Now you try for the
number 9:
Know by heart all pairs of multiples of
ten with a total of 100.
0 + 100 = 100
10 + 90 = 100
Group 3 Learn by Heart Facts
Derive quickly doubles and halves of
multiples of 10 to 100
100 + 0 = 100
Double 10 =
90 + 10 = 100
20 halved =
20 + 80 = 100
30 + 70 = 100
80 + 20 = 100

Continue to practise the ‘If I know, what else do I
know?’ rule eg
half of 60 =
If I know that
40 add 60 makes 100
I also know that 60 plus 40 totals 100
That
100 subtract 40 leaves 60
And that
100 minus 60 equals 40
40 multiplied by 2 =
