The common core standard 1.OA.D.8 asks students to,
“Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _.”
This pack addresses every aspect of this standard.
I know it will be a great addition to your classroom!
