A missing number problem hides one number in an addition or subtraction equation, and the inverse operation finds it. There are 3 worksheets for 6th grade here, each with an answer key. Missing Addends in Four-Addend Sums, Missing Addends in Five-Addend Sums and Find the Missing Minuend or Subtrahend use multi-digit numbers with sums up to 130,403.

Frequently Asked Questions

Add the addends you know, then subtract that total from the sum. In 41 + 75 + a missing addend + 4,190 = 12,855, the known addends total 4,306, so the missing addend is 8,549.
