The Maths Video Section
Technical Stuff: The videos are wmv files which means that they run on Windows Media Player. This is shipped with Windows 7, 8 and Vista. You can download it for free from here.
These videos are designed to provide a reminder of how to carry out specific operations. If you have forgotten how to do something, load the video and see if you can remember. Once you have watched the video a couple of times, you might want to try out the maths spreadsheets to help you to get the idea. Most of these files are large and so will take a long time to download, even if you have broadband. Provided you don't clear your cache, it should be quicker the second time you run it. The number in the second column indicates the approximate size in megabytes of the video file and in parenthesis, I have put the duration of the video.

Grid Method Multiplication. This video demonstrates the method for multiplying two numbers together to find the answer using the grid method. | |
46 (3:28) |
Long Division. This video shows children how to do long division using the arrow method. Be warned that this may not be the way they are shown how to do it in school, but this method is more fun and I refuse to let it die. | ||
|
33 (2:30) |
Multiplication of Fractions is a really useful thing to be able to do. This shows children how to do it. They will need to know their multiplication tables to be able to use this method. | |
65 (4:55) |
Multiplication of Mixed Numbers is just one step on from multiplication of fractions. | |||
|
156 (6:17) |
|
Short Division. This method shows the bus stop method for short division. | |
33 (2:38) |
|
Subtraction using decomposition is a good video for many parents to watch as well as children as this is what replaced borrowing and paying back. | |
|
22 (1:37) |
Percentages using multiplication of fractions as a method. | |
91 (6:49) |
Scaled Area and Perimeter. This is mainly to demonstrate using multiplication of fractions and solving problems. | |||
|
52 (5:31) |
Quadratic Equations using Factorizing. This was put on for a few exceptionally talented mathematicians in Year Six. | |
40 (2:28) |
|
Column Addition allows us to add up many numbers. Important to put each digit in the correct column though. | ||
|
81 (5:01) |
Ratio allows us to work out what each share of something is. | |
66 (4:08) |
|
Long Multiplication allows us to find the product of two different numbers efficiently. | ||
|
56 (3:32) |
|
Addition of fractions with the same and with different denominators. | |
61 (3:50) |
|
Algebra 1 is the first video introducing algebra. It mentions finding an unknown and how to manipulate an equation to find it. | |
|
33 (2:28) |
|
Algebra 2 is the second video in the sequence and it is concerned with separating the unknowns from the numbers. | |
65 (4:36) |
Indices shows you what an index is. | ||
|
46 (3:11) |
|
Pythagorus Theorum allows us to work out the length of a third side in a right angled triangle when we know the other two sides. | |
58 (3:02) |
Multiplication with Counters shows you how you might use counters to multiply one number by another. | ||
|
44 (2:15) |
|
Addition with counters shows you how you can add two digit numbers using counters to help you. | |
68 (3:30) |
Division with counters shows you how to divide one number by another using counters to help you. | ||
|
58 (2:59) |
|
Fractions with counters shows you how you can find a fraction of a whole number by using counters. | |
85 (5:13) |
Finding the equation of a graph can be done easily by finding two co-ordinates along the graph line, finding the difference between y/difference between x, locating the intercept and then putting the figures into the general equation y=mx+c. | ||
|
92 (7:15) |
|
Averages and Ranges covers how to work out the Mode, Median and Mean averages and the range of a set of numbers. | |
311 (24:21) |
 |
Interpreting Graphs is a longer video looking at some SATs questions from Levels 3,4,5 and 6. Level 3 seems to involve finding the difference between one value and another, Level 4 is adding a range of values, Level 5 is looking at a line graph and comparing values and Level 6 is something where you have to think about the data carefully. Coupled with this, you might find Averages and Ranges and Find the Equation of a Graph useful. | |
|
225 (13:09) |
Scattergrams are drawn to see if there is a relationship between one type of data and another. The correct word for this is a correlation. This video talks about picking a sensible scale and then plotting the points on the graph. | |
119 (6:07) |
|
Venn Diagrams were invented by John Venn and we use them to sort out information. | ||
|
221 (12:03) |
Scaling a graph explains how to find the maximum and minimum values in a set of data and to round the maximum up and the minimum down to some convenient figure. You then find the difference in these figures and divide by the number of squares on the paper. | |
185 (9:33) |
Scaling a graph talks about things you need to consider when scaling a graph. | |||
|
107 (5:41) |
Placing axes on a graph talks about where to draw your lines on graph paper and how you need to think about the data you are trying to show to find the optimum position for your axes. | |
135 (9:02) |
Drawing a straight line graph looks at the equation y=3x-7. We use the method of drawing a table to calculate one part of the equation at a time to reach values of y for x between -5 and +5 inclusive. | |||
|
77 (3:54) |
Drawing and measuring an angle is a quick video that shows you how to use a protractor to draw and measure angles by aligning the centre with the point of the angle, aligning the zero line with one of the angle lines and then reading off the angle where the other angle line is. | |
129 (6:46) |
Drawing a pie chart looks at how you can use a protractor to draw a pie chart. Initially, the video details the calculations you need to make in order to achieve this aim. | |||
|
102 (4:08) |
Enlargement of a shape shows you how to use a pencil and ruler to enlarge a shape or to make it bigger. | |
75 (3:56) |
Adding using the Singapore Strip is designed to give you an idea of what clues to look for in a question so that you can add the correct numbers together. | |||
|
24 (1:26) |
Inequalities shows you how solve a basic inequality. | |
36 (2:16) |
Inequalities 2 showing you when you need to change the inequality to its antonym. | |||
|
134 (5:25) |
 |

|
141 (10:27)
|
