Understanding the value of each digit in a 2 digit number

Numeracy game I played today with a group of children.

You need a 2 or 3 sets of digit cards 0 - 9

and a board something like this


Each child to have a board.
Each child in turn picks a card and decides whether to put it in the tens or ones column. Each child then picks a card and puts it into the empty column. What number have they made? Who has the largest number? That child is the winner and is given a counter.

Start again to see who can make the largest number.
You could play it to see who can make the smallest number.
