Fractions are the foundation of math beyond the basic skills of addition, subtraction, multiplication and division. A solid under-standing of fractions helps students understand the nature of numbers and their interactions. In Fairy Fractions, three fairies encounter some coveted fairy dust. As they fight over it, the king appears and tells them they must share it equally among them-selves. The data provided is a picture of a scale measuring out the amount of fairy dust.
LESSON: FAIRY FRACTIONSHow much fairy dust should each fairy receive?
Fairy Fractions
Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, (e.g., by using visual fraction models and equations to represent the problem). For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups of raisins?

Gladys: As you bring 5.NF to a temporary close, consider using class discussion to review terms including product, factor, quotient, divisor and dividend.
Kevin: As this standard is similar to 5.NF.B.7a and 5.NF.B.7b, you may want to have students experiment with dividing non-unit fractions by whole numbers.
Megan: In this standard, students are provided with a story or context around which they will create a diagram, model or equation. Encour-age your students to check their solutions using multiplication.
