This rounding unit is aligned with 3rd grade common core standards, but could be a great review for early 4th grade as well!
Introduce rounding to your students with a hundreds chart that they color code to help them through the unit! Give them lots of practice with rounding to the nearest ten and the nearest hundred with the included worksheets. Students have to identify their two choices for rounding before choosing the correct answer on the first included handout. On the next, they use a number line to visualize the rounding. Finish up with a rounding review worksheet (for both tens and hundreds) and then assess your students with the included quiz!
Check out the preview file for samples of each worksheet and go to my blog for a rounding freebie to go with this unit! (http://third-grades-a-charm.blogspot.com/2012/09/big-news-plus-a-rounding-freebie.html)
