The math block

Math: two-digit subtraction without regrouping

  1. Warm-up: write these on the board and solve them together, asking a student to explain each step: 96 − 65; 25 − 23; 83 − 50.
  2. Hand out the two-digit subtraction without regrouping sheet (16 problems). Print 24; the key is on its own page.
  3. Students work on their own for twenty minutes, then check with a partner.
  4. Early finishers write three problems of their own and swap with a neighbor.

Subbing 2nd grade

Second graders can work on their own for fifteen or twenty minutes, answer questions in sentences, and usually know the class jobs. A clear schedule on the board does most of the managing for you.

  • Write the schedule on the board first thing and cross off each block as you finish it.
  • Use partners for checking answers, not for doing them.
  • Have the extra-time sheet ready: early finishers are the start of most noise.
