Multiplication times table

I noticed last week that a lot of you are still having trouble with knowing your basic multiplication facts. You need to just know this and know it quickly. It will help you with new strategies you are learning in our maths programme. Like multiplying bigger numbers like:

26 x 7

This equation can be broken down using your place value knowledge and your basic facts.

26 x 7  is the same as  (20 x 7) + (6 x 7)

That's because there is 20 groups of 7 and 6 groups of 7.

This is where your basic facts knowledge comes in handy.

If you know 10 x 7= 70 then 20 x 7 must be 140. That's because there are 20 groups of 7 not just 10 groups and 10 groups of 7 is half of 20 groups of 7 so 70 + 70=140

but we are not finished yet, that's only the first part. Don't forget the 6 groups of 7 or 6 x 7. Now you can use the multiplication times table chart found on the left hand side under "Practise your maths" or you just know that 6 x 7= 42.

Now you have to add them together    --   140+42= 182
