Teaching missing numbers in subtraction sentences requires higher order thinking practice. This resource has over 30 no-prep pages that can help your student learn how to solve for the difference, missing subtrahend, and missing minuend. If you aren't sure what these terms mean, that's ok! There are helpful posters included that will help your kids grasp the terms and actually use them appropriately!
Why use these terms: The math standards are clear for both the Common Core and the TEKS.

TEKS - Use objects and pictorial models to solve word problems involving joining, separating, and comparing sets within 20 and unknowns as any one of the terms in the problem such as 2 + 4 = [ ]; 3 + [ ] = 7; and 5 = [ ] - 3.
