In this video segment from Cyberchase, the CyberSquad replaces a piece of track to get the Madre Bonita Express to the Mother's Day harvest.

Students will be able to find the Lowest Common Denominator by using prime factors. They will then add the fractions. This method was developed for students who have problems guessing and checking.

Now that you have mastered the common math operations of adding, subtracting, multiplying and dividing, you are ready to tackle some more challenging, yet practical problems.

Today we are going to work on our fraction knowledge with some fun games and practice identifying sequences (patterns). See if you can find the missing link with the pattern machine.

This undergraduate level course follows Algebra I. Topics include group representations, rings, ideals, fields, polynomial rings, modules, factorization, integers in quadratic number fields, field extensions, and Galois theory.

This arithmetic lesson shows how to order numbers that are expressed as percentages, fractions and decimals. [Arithmetic playlist: Lesson 31 of 38]

This arithmetic lesson presents the concept of negative numbers and shows how to add and subtract them. [Arithmetic playlist: Lesson 29 of 38]

Students will learn the concepts behind fractions, decimals, and percents by using sports statistics found on baseball cards.

A lesson plan for grade 8 Mathematics.

Task Description: Students use fractional parts of a whole, properties of shapes, congruency, and computation using fractions and money to determine the fair value and total worth of eight fields. This approximately 4-week unit centers around understanding fractional parts of a whole and using fractions and mixed numbers to solve problems.

Examples and questions on the subject of turning fractions (containing 10, 100 or 1000 as denominator) into decimals.

Worked examples and questions for pupils to practice converting fractions into percentages.

In Counting on Art, students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts.In Pippin's Story, young children (grades K–3) focus on a painting by African American artist Horace Pippin. They will learn how to "read" the clues in a painting and write a story about the work. Students will also solve counting and time problems and create their own "secret number" painting.Calder's Balancing Acts focuses on math in the mobiles of Alexander Calder. Elementary- level students (grades 2–5) will learn about the artist and write equations based on Calder's art. Upper-level students (grades 6–8) will discover patterns and the Fibonacci sequence. Both levels will make their own math mobiles.Cake Math, based on a painting by California artist Wayne Thiebaud, features math challenges of many varieties. Elementary-level students (grades 2–5) will practice fractions, addition, subtraction, word problems, sorting, and classifying. Intermediate level students (grades 6–8) will find volume and surface area in Thiebaud's cakes.

In this Cyberchase video segment, Shari Spotter gets help from the CyberSquad in doubling a recipe for crumpets.
