Exploring Fractions

See how professional chefs use fractions many times a day to make sure the food they cook always tastes just the way we like it. (1:13)

The MegaHunk Chocolate Bar

When learning to multiply fractions, it’s important to learn how to do the calculations. Using drawings to help you see what is actually happening can be a good way to deepen your understanding. (3:59)

Area Models for the Multiplication of Fractions

Using an interactive grid can make it easier to understand what actually happens when you multiply fractions. (N/A)

Dividing a Whole Number by a Unit Fraction

Dividing whole numbers by fractions can be a hard concept to imagine, but when you see it illustrated using building blocks, it just makes sense. (1:14)

Product of a Whole Number and Fraction

Multiplying a whole number by a fraction (or vice versa) can produce results you might not expect, but using a visual aid will help you to understand what really takes place. (1:23)

Modelling a Fraction Multiplication Word Problem

Studying mathematics can make nature interesting, especially when you use it to learn how much a beetle can lift by multiplying a whole number and a fraction. (2:32)

Modelling Fraction Multiplication with Equal Groups

Using visual models to solve problems involving fractions is a fun way to learn what actually happens. (2:32)

Practising Fraction Multiplication with Equal Groups

This interactive exercise will help you to understand multiplying fractions using fraction bars. (N/A)

Practising Fraction Multiplication with Arrays

This interactive exercise will help you to understand fractions using arrays. (N/A)

Modelling Fraction Multiplication using Arrays

Using a grid is a terrific way to compare fractions visually, multiply them and discover interesting information about the natural world. (2:53)

Modelling Fraction Division using Comparison, Group Number Unknown

Fraction bars are visual tools that help you become comfortable with comparing fractions and using them to calculate answers that provide useful information about the world around you. (3:33)

Modelling Fraction Division using Arrays

Modelling fractions using a square grid can be a good way to learn about dividing fractions to solve a problem and learn something new about nature at the same time. (3:01)

Modelling Fraction Division using Comparison, Group Size Unknown

Dividing fractions can be much easier to understand when you use a visual model. Here’s a way to make a visual model that compares and calculates the results of a frog-jumping competition. (3:04)

Modelling Fraction Division, Equal Groups, Number of Groups Unknown

Using simple diagrams like pie charts is another way to become familiar with calculations that involve fractions with different denominators. (3:22)

Division of Fractions: Connection between Fractions and Division

Dividing two fractions requires finding a common denominator first. Using fraction blocks helps you visualize finding that common denominator and understand why you need it. (2:16)

Exploring Surface Area and Volume

If you’ve ever wondered how the math that describes surface area and volume is used in real-world situations, this video and interactive website provides some fun examples. (1:09)

Surface Area

What is a prism? What other names can be used to describe it? Why would you ever need to know the exact surface area of a prism? Try figuring out how much paint to buy and you’ll have your answer. (N/A)

Exploring Surface Area, Volume, and Nets – Use it

What is a prism and what is its net? Understand and apply these terms and you will have important tools you need to calculate the surface area and volume of 3-D shapes. What for? You just never know when you’ll need to paint the nose cone of a rocket ship or fill it with strawberry jelly. (N/A)

Exploring Surface Area, Volume, and Nets – Explore it

Here is an interactive exercise that lets you experiment and immediately see what happens to 3-D objects when you change their dimensions. (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)
