Teaching Tips

even numbers are easier to understand, ask pupils to line up in pairs, so if it is possible to pair up, the number of pupils is even.

odd numbers is the opposite of even, again, ask pupils to line up in pairs, so if it is not possible to pair up, meaning one pupil has no partner,  the number of pupils is odd.

A Poem on Even & Odd Numbers by Marg Wadsworth

If you are an even number
You always have a pair
So if you look around
Your buddy will always be there
But ...
If you are an odd number
There's always a lonely one
He looks around to find his buddy
But he's the only one.

multiples is easier if it is associated to skip count, so mulitples of three is skip count three, for example, 3 ,6, 9, 12, ....

multiples of three, skip count three, color coded for ease of pattern recognition

factors is the hardest, pairing the first and the last numbers of the factors could help pupils realise 

factors of a numbers colour coded for ease of pattern recognition 1x48 = 2x24 = 3x16 = 4x12 = 6x8 = 48
