Video project - Year 7 review of Fractions, Decimals and Percentages
Fractions, decimals and percentages can be a real sticking point for progressing further in Mathematics from Year 7.
Working with and understanding fractions is also the basis of place value and further multiplicative thinking in algebra. So this video integration project has put together a series of reviewed videos that will help you review the concepts of fractions and how you think about them.
The majority of these resources come from a fantastic site called Math Antics. (http://www.mathantics.com/).
But before you race down below to the video library to watch these videos, take a moment to review the lesson plan just below. It is an integrated physical activity along with a video activity which you will enjoy doing with your class and hopefully you learners will enjoy as well.

Video 1 - Fractions are parts
This video reminds us that fractions are simply a way of representing the division of an object into a certain number of parts. Visual representation of fraction bars are useful to cement this concept in your brain but you must be able to transfer this understanding to a numerical representation to proceed. |
|
Video 2 - Working with parts
This video begins by comparing fractions using the visual representation of a fraction bar. It continues to introduce operations with fractions, such as addition, using a pictoral representation. The term equivalent fractions is introduced for two fractions that have equal values but different numerators and denominators. The lesson finishes with explanation of the procedure for adding fractions with like denominators. |
|
Video 3 - Fractions are division
This lesson covers the essential basics of fractional notation and how it is really just a division problem. It covers a variety of different representations in order to make the normal fraction form seem less confronting. |
|
Video 4 - Types of fractions
This is a fantastic overview of the different types and sizes of fractions, including where they sit on the number line. It covers information often not done in textbooks or traditional formats, that is the zero fraction and equivalent fractions for 1. It also uses good literacy terms such as zero, proper fraction, whole and improper fraction to ensure you are labelling your concepts correctly. |
|
Video 5 - Fractions and decimals
This lesson recaps the concepts covered so far and then links the concept of division in fractions to writing numbers in decimal form. A quick recap of place value and base 10 is also covered before explaining the creation of tenths, hundredths and thousandths using the number line. |
|
Video 6 - Writing base-10 fractions as decimals
This lesson demonstrates how to write special fractions with base-10 denominators, 10, 100, 1000 etc as decimals. It takes you through each conversion with a variety of examples for tenths, hundredths and thousandths. |
|
Video 7 - Converting any fraction
Demonstrates the simple technique of converting a fraction by completing the division. Both the longer division format and a shorter method (ie. using a calculator) are explained. |
|
Video 8 - Comparing fractions
A Maths Antics visually engaging video that numerically demonstrates how to compare fractions of different sizes. Different denominator examples are used along with a review of same denominator. Clear processes are explained, particularly cross multiplying. |
|
Video 9 - Factors and multiples via Prime Factorisation
Describes and explains factorising numbers into their prime factors. The terms prime and composite are explained and used throughout. The easy approach of using a factor tree is also demonstrated with multiple examples and different pathways. This concept underpins all numerical simplification, particularly fraction simplification which is why it is included in this lesson order here. |
|
Video 10 - Simplifying fractions part 1 and 2
This video that links prime factorisation to simplifying fractions. Using clear visual setting out of fraction diagrams the basics of equivalent fractions are covered before moving on to procedural practice examples. Part 1 is essentially the introduction to the procedure and worked examples but Part 2 covers further examples using larger numbers with more factors to consider. |
