Rounding Activities:
The number line is the most powerful tool for teaching rounding but that becomes
difficult with 100’s and 1000’s. But the Enchanted Learning site has a series of number
lines for teaching rounding in the larger numbers. Here is the link http://www.enchantedlearning.com/math/rounding/ It requires a $20 subscription to
become subscriber of Enchanted Learning, but is great resources.
What’s Your Number
Name ________________
Each person in groups of three takes a turn a rolling the die. The students decide where to
put this number in their four digit number to make either the largest number. Don’t let
your partners see the number you are making. There will be five rolls per number. You
may choose to throw one of the numbers in the trash. That is the chance you can take.
Then write all the numbers made on the whiteboard to compare. Which is largest? Then
place them in order largest to smallest. The largest number gets 5 points, middle number
gets 3 points and the smallest gets one point. Total your points after ten rounds to
determine the winner. Now do the game trying to get the smallest number. What
strategies did you learn from the largest number to help you with the smallest number.
This time smallest number gets 5 points, middle 3 points and largest 1 point.
