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

Our Take: Adding and subtracting within 20 should become quick and easy work for students by the end of second grade. Give students plenty of repetition through various types of worksheets and games to hone this skill.

These worksheets can help students practice this Common Core State Standards skill.
