This easy first-grade subtraction worksheet builds early confidence with facts within 10. Children solve eight straightforward subtraction equations, then complete five fill-in-the-blank story sentences like 'Start with 9, take away 4, and you have ___ left,' which connect symbols to real take-away language. Three true-or-false statements such as '10 - 5 = 5' wrap up the page, encouraging young learners to check answers carefully and notice when a subtraction fact looks right but isn't.
