Use arrays to establish multiplication facts from multiples of 2 and 4, 5 and 10
Relate doubling to multiplication facts for multiples of 2
Recognise that doubling is multiplying by 2 and halving is dividing by 2 (Reasons about relations)

Playing cards
Players form pairs.
Display exercises for players to see.
A variation on 'Go Fish' where players try to make pairs with cards that are the same and then calculate the doubles fact.
Each player gets 7 cards. The rest of the cards are placed in a pile in the middle as the draw pile.
Players try to make matches, that is, pairs of cards that are the same.
For the player to keep the match they must solve the doubles fact. For example, if a player collected a double 9, they must solve and say ‘double 9 is 18’ to their opponent and then perform the appropriate exercise for 18:
2 = squats
4 = wall sits
6 = front plank
8 = side plank L/R
10 = jumping jacks
12 = marching in place
14 = sit-ups/curl-ups
16 = squat jumps
18 = skier jumps side to side
20 = yoga tree pose
22 = butterfly stretch
24 = toe touches
Once players can't make any more matches using their own cards, they can take turns to ask their opponent for a card.
If their opponent has a card of that number they must give it to the asking player.
If they don't, they say 'go fish' and the player gets a card from the central pile of cards.
If at any point a player has no cards left, they can pick up another 7 cards from the draw pile.
Play continues until all there are no cards left in the draw pile and/or all matches have been made.
The player with the most matches at the end is the winner!
