This is a game I used when I taught 2nd grade.
I used the overhead projector, but a Smartboard would be even better.
Divide your class into 2 teams.
Choose a Team Leader (I usually chose someone shy).
To keep the momentum going, the teacher rolls a large dice.
The first team decides if they would like to use that number
in the hundreds, tens, ones place or in the trash can.
I ask them to huddle together, make the decision together, once everyone agrees,
the Team Leader raises their hand to voice the decision.
Repeat the process with the second team.
The team with the largest number wins!
This is a fun way to reinforce place value.
Students quickly realize larger digits in the hundreds place is best,
and smaller digits go into the.......Trashcan!
