These sorts make a good beginning lesson for your whole class when introducing the rounding unit. Most of your students will catch on after just a few sorts, but I included lots of extras thinking of students who need extra practice. These rounding sorts are designed to isolate the very basic rounding skill of choosing which 10 or 100 a number is closest to.
How the sorts work:
Have students cut the numbers apart and then glue them in the correct column. The beginning sorts and the 2-digit sorts will be easier. You can start at the beginning for struggling students, or you can opt for 3 column sorts for students who grasp rounding easily.
Ideas for Use:
small group intervention, individual math tutoring, partner work, math centers, early finishers, independent seat work, homework, morning work, spiral review, emergency sub activity, simple assessment activity
For students who need extra help, you can use these as a one on one or small group intervention. You can have students first put the numbers in order from greatest to least. Help them identify what the halfway point would be. For example, if you are doing Sort A.1, the halfway point between 10 and 20 is 15. So teach students that anything below 15 rounds to 10 and anything 15 or higher rounds to 20.
There is a half-page included with ideas for early finishers or students who grasp rounding easily. They can put the numbers in order to practice place value skills, find the sum of each column to practice addition skills, and find the difference between the columns to practice subtraction.
