If your student is a year younger but already steady on fraction addition & subtraction, the page still works. You may just need to read the instructions out loud. And if they are older and add unlike fractions never quite stuck, this is a short review rather than busywork.

Can I use this add unlike fractions worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 6th Grade fraction 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 add unlike fractions. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How do you add fractions with different denominators?
⌄
Find a common denominator, rename both fractions and add the numerators. For 1/2 + 1/3, that is 3/6 + 2/6 = 5/6.
What do you do when the sum is more than 1?
⌄
Write it as a mixed number in simplest form. For example, 11/12 + 3/10 = 1 13/60.
Do these worksheets have answer keys?
⌄
Yes. Both sheets have an answer key with each sum in simplest form.
