Rounding Roller Coaster Hundreds Chart Student Coloring Activity
The Rainbow Rounding Roller Coaster gives a visual, hands-on representation of rounding concepts. For some students, rounding by place value and the memorization of rules or rhymes is extremely difficult.
This activity is hands-on and produces an attractive product that they can keep at their desks to help when they are rounding to tens. It can be easily adapted to rounding to other place value increments by writing in or imagining zeroes in the ones place.
Have students color the numbers that round to the same ten the same color. For example: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 would all be colored the same.
After coloring is completed, have students fold their hundreds chart so that the fives are at the "top of the hill" and the tens are at the "base of the hill".
