This pack is part of my lessons by the standards series. One pack for each common core math standard for second grade.

**This is part of my Lessons By the Standards Growing Bundle. If you've already purchased that, you don't need to purchase this.**

The common core standard 2.OA.B.2 asks students to,


“Fluently add and subtract within 20 using mental strategies*. By end of Grade 2, know from memory all sums of two one-digit numbers.”

Use strategies such as counting on; making ten ; decomposing a number leading to a ten; using the relationship between addition and subtraction; and creating equivalent but easier or known sums.


This pack addresses every aspect of this standard.

I know it will be a great addition to your classroom!
