In Rounding Robins each student/group gets a number of dice. They roll the dice to make a number and then pick a card from the stack. They then have to round that number they created based on what the card says. There is a worksheet to help students along that is differentiated for rounding up to thousands all the way to millions.
This activity can easily be used for various grades and student levels. Use the cards needed for however high students would round.
