Grade 2 is where arithmetic starts to become strategic. Students should move beyond counting by ones, understand hundreds-tens-ones, use regrouping with meaning, and apply operations to money, time, measurement, arrays, and data.

Make computation strategic
Addition, subtraction, regrouping, and number-line jumps turn arithmetic into explainable choices.
3
Transfer to real contexts
Money, time, measurement, graphs, and shapes help students use math language outside plain equations.
