Missing Addends in Four-Addend Sums

Ask students to name the inverse operation before solving each equation. Have them check by putting the answer back into the equation.

Find the missing addend in 5 four-addend equations with sums such as 12,855 and 130,403. The directions on the page read: Find the missing addend in each equation. Show your work in the space under each equation. An answer key is included.

Yes, both. We made it for 6th Grade addition & subtraction, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with missing number problems. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

They are the arithmetic behind one-step equations like 41 + 75 + x + 4,190 = 12,855. Solving them with the inverse operation prepares students for algebra.

Put it back in the equation and add all the addends. If the total matches the sum, the answer is right.

Yes. Addends go up to 88,313 and sums up to 130,403, so most problems need regrouping across several places.
