This challenging worksheet stretches first graders with word problems that hide the unknown in different spots. Kids work out how many grapes Leo ate when 4 are left from 10, how many ducks swam away when 3 of 9 stay in the pond, and how many of Ava's 7 stickers remain after she uses 4. They also reason from 8 - 2 = 6 to 8 - 6, then finish five missing-number equations like ___ - 7 = 2, 8 - ___ = 0, and ___ - 6 = 4.
Mixing change-unknown and start-unknown problems prepares first graders for the harder word-problem types they will see on grade-level assessments.
