This medium worksheet pushes first graders past simple difference-finding and into missing-number thinking. Nine fill-in-the-blank equations ask kids to figure out what is taken away or what the start number was, including 10 - ___ = 1, ___ - 4 = 5, 8 - ___ = 4, and 6 - ___ = 0. A four-pair matching section then connects facts like 9 - 2, 10 - 4, 8 - 1, and 7 - 5 to their differences.
Solving for the missing piece forces children to think about the relationship between addition and subtraction, the exact bridge they need before fact families.
