2.OA.A.1 Use addition and subtraction within
100 to solve one- and two-step word problems
involving situations of adding to, taking from,
putting together, taking apart, and comparing, X X X X X
with unknowns in all positions, e.g., by using
drawings and equations with a symbol for the
unknown number to represent the problem.
2.OA.B.2 Fluently add and subtract within 20
using mental strategies. By end of Grade 2, X
know from memory all sums of two one-digit
numbers.
2.OA.C.3 Determine whether a group of objects
(up to 20) has an odd or even number of
members, e.g., by pairing objects or counting X
them by 2s; write an equation to express an
even number as a sum of two equal addends.
