Maths card game - Total of 10

Set out 20 cards face up on the table (with picture cards removed). The first player takes 2 or more cards off the table which have a total of 10. The aim of the game is to clear the table and be the player with the most cards at the end.
The game can be played with younger children to practice number bonds, or can be adapted to make it more challenging - increase the total or bring in subtraction too.
