How is the 5th grade sheet different?

Larger denominators and bigger wholes, so answers like 3 5/6 come from real division rather than pictures. That's the 5.NF.B.3 connection: a fraction bar is a division sign.

Why does this skill matter in fifth grade?

Adding and multiplying mixed numbers both start with a conversion. A child who converts without thinking has attention left over for the actual arithmetic.

How to teach this

Connect every conversion to division: 23/6 literally asks 23 ÷ 6, and the remainder becomes the new numerator. Have your child check one answer per row by converting it back the other way. Skip the drawings at this point unless an answer is wrong. The fifth grade goal is speed with understanding.

Watch for: Kids write the leftover over the wrong number, turning 7/4 into 1 3/7. The remainder stays in fourths, so it sits over the original denominator. Kids add the whole number straight to the top, turning 2 1/3 into 3/3. The 2 is worth 6 thirds, so multiply by the bottom before adding.
