it's worth knowing and being able to recognise square numbers, cubed numbers and prime numbers

Can I add triangle numbers to that list too. Easy to work out but quicker if you know them.

The lovely thing about 13x13 = 169 and 14x14=196 is that the digits used in the answers are the same so children just need to know 13x13 and then swap the last two for 14x14.
