The "lessons" below could also be described as animations or even as slide shows. In fact, we are not exactly sure what to call them! They illustrate concepts and steps required to carry out different operations. They have audio commentary although they can be viewed with just the text. The first six lessons cover fractions.

The links below will open the lessons in a new window. There is a navigation bar at the bottom each lesson that will allow you to:

Pause and play the lesson
Skip through different sections
Switch the audio on and off
View the lesson in full-screen mode
See thumbnails of each screen and skip around the lesson

We would really like to hear what you think about these fraction lessons. We will use what we learn to make them better.

Fractions Lessons

	#1: Introducing Fractions (2:42 min.) This lesson introduces the concept of fractions as being part of one whole unit. It illustrates how numerators and denominators are used when writing and saying fractions.
	#2: Equivalent Fractions (3:41 min.) The concept of equivalency of fractions is explored with examples of finding equivalent fractions by multiplying and dividing the numerator and denominator by the same number.
	#3: Common Denominators (4:10 min.) The need for and use of common denominators are discussed in this brief lesson. Guidance on how to find common denominators using least common multiples is shown.
	#4: Adding and Subtracting Fractions (3:46 min.) Examples are illustrated showing how to add and how to subtract fractions. These include adding and subtracting fractions with both the same denominator and with different denominators.
	#5: Simplifying Fractions (3:12 min.) Two different methods of how to simplify fractions are shown. One involves dividing the numerator and denominator by their greatest common factor. The other uses more of a "keep dividing until you can't divide anymore" method.
	#6: Mixed Numbers and Improper Fractions (4:12 min.) The final lesson in the series covers when to use mixed numbers and when to use improper fractions. It shows the steps to convert between both formats.

You will also find more text-based guidance on how to work with fractions here. There are also a number of fraction worksheets as well as some fraction games.
