Making Friendly Numbers
Learners practice friendly numbers.
Print or draw this Friendly numbers board
- Print (or hand-draw) the friendly numbers card sheet (see example below). Each two digit number on the cards has a corresponding one digit number that when added together will result in a ‘friendly number’ (or a multiple of 10) i.e. 42 and 8, 24 and 6, 39 and 1.
- Hand out one card to each learner.
- Ask learners to turn their card outwards to others can see their card. Learners must go around the room and find a partner to make a ‘friendly number’ with.
- Learners stand with their partner and once everyone has found a partner, pairs take it in turns to tell the class the friendly number they made. E.g. if two learners have 39 and 1, they will say ‘My friendly number is 40’
It is very easy to make your own set of cards with larger or smaller numbers depending on the number range learners are comfortable with
