Tens and Ones Trading Game

A very important skill that the first graders have been working on is counting tens and ones and exchanging ones for tens.  One game that the children really like to play is the Tens and Ones Trading Game.  Players take turns putting base 10 blocks on the Tens-and-Ones Mat according to the roll of a die.  Whenever possible, they exchange 10 cubes for 1 long.  The first player to get 10 longs wins.
