Numbers & Math · Grade 2 · Chapter 23: Bigger subtractions

Skills to explore

• Bigger subtractions
• Bigger additions

Ages 7–8: practice more independently, then explain the reasoning together. Revisit earlier chapters whenever helpful.

Connect number symbols with groups of objects, compare quantities and explore arithmetic through picture-based activities.

Learning levels are starting points, not assessments. These activities supplement learning with a grown-up; they do not promise school readiness or replace a curriculum. Take breaks and choose a level that feels comfortable.
