A simple Halloween week plan
Halloween week is busy, so this one is three days — about 15–20 minutes a day:
- Day 1 — Play. Monster Mash Math at your child’s level. Let them pick Hatchling/Creeper (K–2) or Ghoul/Boss Monster (3–5).
- Day 2 — Print. One worksheet set matched to the same level (links above). Answer key is on page 2.
- Day 3 — Print fresh or play up. Re-open the same worksheet link — the generator makes a brand-new set — or try the next game level. For a reading break, pick a fable from Classic Story Shelf.
