Gr 2 Unit 1 - Extending Number Sense (Numbers to 100)

*The focus in this unit should be on solidifying student understanding of numbers to 20 (from Gr 1) and gradually increasing the set size beyond 20. It would be appropriate for students to be working with any two-digit number, however, proficiency with the full range of numbers 20 - 100 is not expected in unit 1. Work with base ten materials should be delayed until after countable, groupable objects (ex. popsicle sticks, straws, linking cubes, etc.) have been used to develop the understanding of grouping to make counting and working with numbers more efficient and easier. Base ten materials should be introduced no earlier than unit 3.
