This is a simple way to teach rounding to the nearest 10. Rounding is a difficult concept for many students. I combine this SmartBoard activity with the visual of a helium filled balloon to teach when to round up or down. Just have students click on the balloon to see if the number rounds up or down.
I used this when teaching rounding to my 3rd, 4th, and 5th grade special education students with great success.
