4 x 5 =20
This multiplication sum
is 4 lots of 5. Shown as a repeated addition it looks like this 5 + 5 + 5
+ 5 =
There are several ways a child could solve this depending on how confident
they are with different methods.
1. They could count in 5's 4 times - 5 10
15 20.
2. They could just count on - put 5 in their head and count on the rest
but the pitfall here is losing count.
3. They may be aware that 5 + 5 = 10 and that they have this sum twice and
that double 10 = 20
4. They may decide to do it like so:
Using an array
An array is a pictorial representation of the sum e.g. 4 x 3 =12
1. Children decide that 4 x 3 is 4 sets of 3.
2. They draw 4 circles (could be any shape but circle is quickest.) to represent the 4 sets.
3. They then put 3 spots on each circle.
6 Remember to write the answer by the original sum or question.
