In this lesson video you’ll learn multiple ways to divide a number by a fraction; plus you’ll get actual examples to make this concept real.
This video helps students practice decomposing fractions to get ready for mixed numbers and performing operations with fractions.
In this lesson, students are asked to share certain numbers of objects among different numbers of people. They begin with unit fractions and move to divide multiple objects (a) among multiple people, (b) in which a < b, to produce fractions less than one. This CYBERCHASE activity is motivated by two video clips in which the CyberSquad has to share objects fairly in order to overcome obstacles and challenges assigned to them by Zeus as they try to recover Pandora's Box, which was stolen by their nemesis, Hacker.
In this interactive lesson, students will build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers. They will understand a fraction a/b with a > 1 as a sum of fractions 1/b and decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation.
While doubling a cupcake recipe, students practice three ways of doubling fractions using representations, addition, and multiplication. They also convert between improper fractions and mixed numbers.
Students will analyze the painting, Cakes, by Wayne Theibaud. They will practice fractions and paint a decorated cake.
In this interactive activity, students will be led through steps to add and subtract mixed numbers. There are teaching activities as well as practice activities available. A handout that reviews the strategies taught in the interactive can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
In this interactive activity, students will be led through steps to add and subtract fractions with like denominators. There are teaching activities as well as practice activities available. A handout that reviews the strategies taught during the activity can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
Use a visual model to subtract fractions with like and unlike denominators. This video focuses on using an equivalent fractions chart to compare fractions and find the missing piece.
Use a visual model to add fractions with like and unlike denominators. This video focuses on using an equivalent fractions chart to compare fractions and find the correct sum.
In this video segment from Cyberchase, the CyberSquad has to help Shari Spotter make a batch of Cosmic Crumpets in order to give the masters at Frogsnorts their power. The recipe they have is for four crumpets, but they need to make eight crumpets. Everything in the recipe has to be doubled, including some tricky fractions which Shari and the CyberSquad find they must convert from improper fractions to mixed numbers.
To decompose means to break apart. Students already decomposed whole numbers with number bonds, tape diagrams, and place value charts. In fourth grade, they will decompose fractions.
