Playing card maths

At 'snow school' today, the kids did a bit of maths using a deck of playing cards.
Here, Honor is calculating 5 0r 6 numbers from cards dealt out at random using number bonds and knowledge of multiples as strategies for quick mental addition.
So from these cards she picks out the two cards that make 10...

... then adds on the next biggest number to make 16 and finally adds 2 x 1 to make 18.
From these cards, she found 3 x 10 and then added 2x3 to make 36.

Henry is in year 1 at school and is learning his number bonds to 10.
Here, he is matching the correct numbers to 10. He needs to practise this a bit more, but I think he nearly has it.
