rounding
By kat

I just got a great idea and will even try it with my classes. Have a group of preprinted numbers to give to the students. have another set of numbers to place around the room that would be what the numbers are rounded to. If I wanted them to round to the nearest hundred I woul have 100,200,300,400,500,600,700,800,900,1000 placed around the room. They would take their numbers and put them in the right spot. #467 would go to 500 spot.

You could also have a blank BINGO board and let them fill in a list of numbers randomly and then you could call out 300 and if they had a number that would be rounded to 300 they would cover that spot. Doesn't require movement, but it's another approach.
