This challenging Grade 1 worksheet pairs four multiple-choice questions with five fill-in-the-blank items, pushing first graders past the easy-level routines. Multiple choice spans 14 - 8, 9 + 7, the classic 'What does a ghost say?' answer of boo, and identifying a costume as the Halloween wardrobe item, so children alternate between arithmetic and Halloween reading clues without warning.

Fill-in-the-blank then asks for sums and differences like 11 + 8, 20 - 6, and 15 - 8, plus sentence answers including 'Witches brew a magic ___' (potion) and the candle inside a jack-o-lantern. It is a strong end-of-unit review of addition within 20, subtraction within 20, and seasonal vocabulary recall.
