This mini-unit focuses on rounding 2 and 3 digit numbers to the nearest 10 or 100. There is a whole group activity for getting students rounding numbers. Then you can move on to the 3 sets of task cards. Each set includes 10 task cards. There is a student answer sheet and answer key for the task cards. I have also included three worksheets to use for independent work.
These are directly aligned to Common Core NBT.1
