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.

⌄
Find a common denominator, rename both fractions and add the numerators. For 1/2 + 1/3, that is 3/6 + 2/6 = 5/6.
