Unit: 3.1

Wrapping up 1,000

In this unit students

•  round to the nearest 10 and 100;
•  add and subtract within 1,000.

Students begin by revisiting their work on addition and subtraction of whole numbers from Grade 1 and extend it to addition and subtraction within 1,000. If students start with this unit, there will be time for them to revisit the ideas as needed throughout the year until they develop fluency with those operations.
