Rounding Around the Room is an activity the kids love! This is a perfect review of rounding concepts. I like to do Around the Room activities the day before the test.

This Around the Room set is designed for with the CCSS of 2nd grade in mind, but can easily be used for 1st grade as an extension activity or in 3rd grade as a review of place value. The CCSS addressed with this activity are:
**2.NBT.1 Understand tha the three digits of a three-digit number represents amounts of hundred, tens, and ones
**2.NBT.2 Count within 1,000; skip-count by 5s, 10s, and 100s
**2.NBT.3 Read and write numbers to 1,000 using base-ten numerals, number names, and expanded form.
**2.NBT.4 Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using symbols to record the results of comparisons.
**2.NBT.8 Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.

This activity can be used as a self-directed center or a whole group activity. When used for a whole group activity, students have one minute to answer a question before moving to the next one.
