My Learning at home

I am in Grade 8 – Mathematics

 

Number

Fractions in Real Life

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)

Multiplying Fractions

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 Fraction

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)

Multiplying a Whole Number by a Fraction

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)

Multiplying Fractions

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)

Dividing Fractions

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)

Dividing Fractions with the Same Denominator

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)

Dividing Fractions using a Common Denominator

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)

Shape and Space

Surface Area and Volume in the Real World

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

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)

3-D Objects

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)

Volume and Surface Area

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)

Statistics and Probability

Expressing Probability

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)
