As a student, you'll encounter vast amounts of information. Beyond academic material, you must process and interpret news, instructions, communications, and a wealth of other data. You'll also need to separate fact from opinion, and understand the quality of sources. The stronger your reading capabilities, the more efficiently and effectively you can turn information into knowledge.

Outcomes

In this course you will learn about:

1. Equivalent forms of fractions.
2. Addition of fractions.
3. Subtraction of fractions.
4. Multiplication of fractions.
5. Division of fractions.

This YouTube video introduces Grade 8's / Form 1's to the basics of fractions.

Unpacking the concept of writing fractions in the simplest form.

• Describe a model for friction a molecular level.
• Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the temperature affects the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.

Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity.
