The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.
This task requries students to think about division by fractons.
The purpose of this task is for students to compare a number and its product with other numbers that are greater than and less than one.
The purpose of this task is to have students think about the meaning of multiplying a number by a fraction, and to use this understanding of fraction multiplication to make sense of the commutative property of multiplication in the case of fractions.
This task gives students word problems with a given a set of a specified size and a specified number of subsets. The questions ask the student to find out the size of each of the subsets.
One common mistake students make when dividing fractions using visuals is the confusion between remainder and the fractional part of a mixed number answer.
The purpose of this task is to help students explore the meaning of fraction division and to connect it to what they know about whole-number division.
In this activity, students make use of a visual representation for dividing fractions. They also discover the numerical algorithm used to divide fractions.
Practice dividing fractions by fractions. No negative numbers are used in this exercise. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Developing a concrete and conceptual way to divide fractions helps students understand the "why" part of the process.
Computing with fractions allows students to develop a strong number sense
This lesson completes the conceptual understanding of dividing with fractions by using it with real life problems.
What do you get when you divide 1/4 by 1/2? What does your answer actually mean? Students continue building their skills and strategies in order to divide fractions by fractions.

Explore division by modeling problems and grouping with manipulatives. This video focuses on dividing whole numbers by unit fractions and modeling the problems with unit blocks.
This task requires students to recognize both "number of groups unknown" and "group size unknown" division problems in the context of a whole number divided by a unit fraction.
This task builds on a fifth grade fraction multiplication task and uses the identical context, but asks the corresponding ŇNumber of Groups UnknownÓ division problem.
