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!
