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


The 2.OA.2 activities that are included in my short answer, centers, printables, and interactive notebooks are similar but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the 'Apply new skills' part of MATH groups.
