This short video and interactive assessment activity is designed to teach fourth graders about adding and subtracting fractions - word problems.

The math learning center is an app and online platform that allows students to use manipulatives virtually. In this activity, students will use virtual manipulatives to add fractions with unlike denominators

The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.

The focus of this task is on understanding that fractions, in an explicit context, are fractions of a specific whole. In this problem there are three different wholes: the medium pizza, the large pizza, and the two pizzas taken together.

Countdown Fractions in this Nrich game offers a motivating context in which to practice calculating with fractions. There is usually more than one way of hitting the target, which offers an opportunity for rich discussion on the merits of alternative methods.

This Nrich problem gives learners practice in fractions (tenths) as well as in addition and subtraction in a challenging form.

This short video and interactive assessment activity is designed to teach fifth graders about fractions with common denominators - word problems.

This is the first Nrich problem in a set of three linked activities. Egyptian Fractions and The Greedy Algorithm follow on.

It's often difficult to find interesting contexts to consolidate addition and subtraction of fractions. This problem offers that, whilst also requiring students to develop and analyze different strategies and explain their findings.

This Nrich activity is an unusual context in which pupils can consolidate recognizing, finding, naming and writing fractions. The rich environment also gives them the opportunity to identify, name and write equivalent fractions of a given fraction, represented visually as a chain. Furthermore, learners will be adding and subtracting fractions with the same denominators and denominators which are multiples of the same number.

This short video and interactive assessment activity is designed to teach fifth graders about adding fractions with common denominators.

Visnos is an interactive math website that provides many different math tools to allow teachers to show math visually and allow students to explore with the tools.Visnos can be used with grades one-five as there are activities for telling time, fractions, multiplication tables, subtraction facts, angles, measurement using a protractor.
