4th grade sub plans: math

A 4th grade math block for a substitute, 65 minutes: a warm-up on the board, then equivalent fractions practice (a sheet with its answer key on its own page), partners checking each other, and early finishers writing problems of their own. 4 steps, written to be read once and followed.

Checked October 30, 2026. Made from Peabody Teach's own passages, worksheets and brain break cards.

The math block

Math: equivalent fractions

  1. Warm-up: write these on the board and solve them together, asking a student to explain each step: 4/6 = 8/; 1/2 = 5/; 1/5 = ____/20.
  2. Hand out the equivalent fractions 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 4th grade

Fourth graders can run a lot of their own routines if you let them, and partners and table groups work well. The math often reaches long division and fractions this year, so the plan keeps math to facts and practice they already know.

  • Give the class a job to run: handing out papers, the timer, the lunch count.
  • Let partners check answers against each other before you go over the key.
  • Collect every paper in one pile per block, labeled, for the teacher.
