Exploring Fractions

What exactly is an equivalent fraction? This visual app will help you to understand why some fractions that look different mean the same thing. (N/A)

Visualizing Equivalent Fractions

It’s easy to learn about making equivalent fractions if you represent them with a diagram.
(3:52)

Equivalent Fraction Word Problem: Example1

Here’s a word problem about equivalent fractions. Watch the video to see how a simple diagram allows you to solve the problem. (4:00)

Equivalent Fraction Word Problem: Example 2

Two diagrams of the same size have different numbers of sections. Here’s how to solve a word problem by using equivalent fractions and illustrating them visually. (2:00)

Equivalent Fraction Word Problem: Example 3

In this problem, one diagram is compared with four others using equivalent fractions to find which of the four is the same.

Comparing Fractions with the “Greater than” or “Less than” Symbols

Fractions have a top number and a bottom number. Learn what the numbers mean and how to compare different fractions to each other. (5:18)

Comparing Fractions with Like Numerators and Denominators

Compare fractions with the same top numbers, and compare fractions with the same bottom numbers. Learn about a special symbol that shows whether one fraction is smaller or larger than the other. (4:47)

Comparing Fractions

Compare fractions with different top numbers called numerators and different bottom numbers called denominators. The results might surprise you. (2:29)

How to Add Fractions with Different Denominators

Learn what a lowest common denominator is, how you can find one and how you can use it to add two fractions that seem like they have nothing in common. It’s easier than you think. (5:00)

Adding Fractions

In mathematics, fractions describe a part of a whole number. If you want to add two fractions, you need to make both have the same denominator. Finding the lowest common denominator makes the fractions easier to add. (4:27)

Visual of Subtracting Fractions

Mixed numbers are just whole numbers with fractions. When learning how to subtract mixed numbers, it might help you to visualize slices of pizza. Eat some slices, count what’s left and you have your answer. (2.50)

Solving Equivalent Fraction Problems

Learning to visualize and combine fractions to make whole numbers can help you to make sure you have enough materials to succeed with a building project. (3:25)

Adding and Subtracting with Unlike Denominators

An example taken from everyday life uses a ruler to explain how you can add fractions with different denominators and why it is a useful math skill to learn. (3:25)

Addition of Fractions using a Visual Model

If adding fractions with different denominators is difficult for you, this chart helps you to understand and shows why common denominators are used. (1:58)

Subtraction of Fractions using a Visual Model

If you’re trying to subtract fractions with different denominators, here is a chart that helps you to figure out how and illustrates why using a common denominator is important. (1:02)

Explore the Relationship among Fractions, Decimal Notation and Percentages

Fractions, decimals and percentages are all related. Three short videos tell you how you can convert back and forth between them all, a useful addition to any mathematics toolbox. (4:34)

Fractions, Mixed Numbers and Decimals on the Number Line

This interactive exercise will help you to understand ordering fractions by placing them on a number line. (N/A)

Adding Fractions and Decimals from 0 to 1 on the Vertical Number Line

This interactive exercise will help you to understand how to use a number line when adding fractions with like and unlike denominators. (N/A)

Adding Fractions, Mixed Numbers and Decimals on the Number Line

This interactive exercise will help you to understand how to use a number line when adding fractions and adding decimals. To complete some of the exercises you will need to know that there are 12 inches in a foot. (N/A)

Converting Rational Numbers

Rational numbers can be hard to work with for many reasons. Learning to convert them to decimals can make calculations more straightforward, unleashing the student's powerful mathematics potential in the process. (1:54)

Probability

Drawing coloured marbles from a bag, spinning a number dial and flipping a coin are all exercises that will help you to learn about determining probability, making predictions, and comparing the theoretical to what actually happens. (N/A)

Probability

Can you express things like probability or chance mathematically? You may be surprised to learn you can. Here’s a fun way to learn how. (N/A)

Exploring Probability

Few things can help you understand the difference between theoretical probability and reality faster than playing a game of chance. In this game, you only get to play when you demonstrate that you understand the underlying theory. (N/A)
