Numeracy Intervention

Back in 1961, Bobby Darin sang

 

 

Multiplication that’s the name of the game

And each generation they play the same’,

 

But is this still the case?

Do we need our children to learn how to multiply the way we were taught?

The answer is ‘No’!

 

 

 

Even though it’s still important for children to learn their ‘multiplication facts’, (not times tables), it is  vital they have a strong, clear understanding of what multiplication means (i.e. groups of) and what this looks like. For example, the array below can be read as 2 X 6 or 2 rows of 6; or if looked at from another side it would be seen as 6 X 2 or 6 rows of 2.

One way we can teach children to solve a problem such as ’14 X 12’ is by using the ‘Area Method’.

 

 

The photo below shows

that by dividing the large array (14 rows of 12) into smaller arrays, such as 10 X 10; 4 X 10; 4 X 2 and 10 X 2 it is easier to answer the smaller arrays and then add the amount together.

 

By using this method, children get to manipulate numbers by creating arrays (areas) they are comfortable with and visualising what they look like.
