These problems are meant to be a progression which require more sophisticated understandings of the meaning of fractions as students progress through them.
This task addresses the division problem 4Ö1/3.
This task provides a context for performing division of a whole number by a unit fraction. This problem is a "How many groups?'' example of division.
This short video and interactive assessment activity is designed to teach fifth graders about identifying equivalent fractions (missing number).
This lesson unit is intended to help teachers assess how well students are able to interpret percent increase and decrease, and in particular, to identify and help students who have the following difficulties: translating between percents, decimals, and fractions; representing percent increase and decrease as multiplication; and recognizing the relationship between increases and decreases.
This short video and interactive assessment activity is designed to teach fifth graders about inequalities with addition and subtraction of fractions.
Many GED/ESL students have a lapse in education. As a result, the concept of fractions is a difficult task to teach to the adult learner. This OER will give the student the basic introduction to the concept of fractions. Gaining confidence the student can move on to higher level mathematics.
This resource was created by Staci Simonsen, in collaboration with Lynn Bowder, as part of ESU2's Mastering the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education and experiential learning.

The purpose of this task is to present students with a situation where it is natural to add fraction with unlike denominators; it can be used for either assessment or instructional purposes.
The purpose of this task is to present students with a context where they need to explain why two simple fractions are equivalent.
Students will review and practice the concepts of least common multiples. This is a great tool to use for extra practice or review for a test.
This lesson introduces fractions, numerators and denominators and shows how they can be useful in everyday life.
Students will create their own graph to practice.

This is a challenging fraction comparison problem. The fractions for this task have been carefully chosen to encourage and reward different methods of comparison.
This task requires students to represent fractions on a number line.
In this number line task students must treat the interval from 0 to 1 as a whole, partition the whole into the appropriate number of equal sized parts, and then locate the fraction(s).
This task is a straightforward task related to adding fractions with the same denominator. The main purpose is to emphasize that there are many ways to decompose a fraction as a sum of fractions, similar to decompositions of whole numbers that students should have seen in earlier grades.
This tasks lends itself very well to multiple solution methods. Students may learn a lot by comparing different methods. Students who are already comfortable with fraction multiplication can go straight to the numeric solutions given below. Students who are still unsure of the meanings of these operations can draw pictures or diagrams.
The purpose of this instructional task is to motivate a discussion about adding fractions and the meaning of the common denominator. The different parts of the task have students moving back and forth between the abstract representation of the fractions and the meaning of the fractions in the context.
