What your learner will practice
Building two-digit confidence. Second graders connect place value to addition, subtraction and familiar everyday situations. Encourage grouping into tens and ones.
With addition in Grade 2, the goal is to build understanding and to explain the method, not just get a number. Take breaks and repeat short sessions when needed.
How to solve addition problems
- 1Start with the larger addend and count on, or group numbers by place value.
- 2Line up tens, hundreds, and ones when adding multi-digit numbers.
- 3Check by subtracting one addend from the total.
Common mistake to watch for
If the total is smaller than an addend, look again at the place values.

Helpful teaching idea
Ask: Which two amounts are being combined? Draw a quick model if needed.
Try a short warm-up, then have the learner explain one problem with a drawing or written number sentence.
