Meet Salman Khan. He has put free maths on-line.
This article on Salman appeared in The Sunday Times, UK, 12 JUN 2011.
Salman, 28, started putting tutes online for his 12-year-old niece, Nadia, and things grew. So far the Kahn Academy’s claim to fame are:
* Over 2,400 videos including hundreds and hundreds of 12-minute maths tutes
* Over 63,000,000 lessons delivered.
* Bill Gates kids use the site.
* A staff of 1 with funding from The Bill and Melinda Gates Foundation.
* Tutes on Biology, Chemistry and Physics too.
You can look up the maths tutes by topic @ The Khan Academy.
Or search topics on Youtube eg. Introduction to Conics Khan
Why Does Mathspig like The Kahn Academy? Because it’s:
Salman gives digital chalk-and-talk tutes like a teacher. He hand draws the equations and graphs. He uses a calculator from time to time, but he tends not to use whizz bang spreadsheet graphs or perfectly presented textbook equations. It’s a bit wobbly and it’s all coming from Salman’s head.
And students like this approach. It makes maths look do-able.
Mathspig thinks you are just GORGEOUS!!!!!!!!!
Australia’s Year 7 – 12 Maths Curriculum is already on-line and free, funded by McDonald’s. See What are maths teachers for, sir?
The tutes on Maths Online are produced by Aussie Maths teachers and they are very good. Mathspig, of course, imagined the quadratic function tutes might look something like this:
Introducing FRIDAY MATHS MADNESS for Maths Piglets (Prep – Grade 2)
It is Friday, the weather is improving, it’s time to take maths outside. You mathspigs know about Gardner and Multiple Intelligences. This week’s exercise involves kinesthetic learning.
Thanks to mathspigs Sophie and Ivy, both 7, for the Pig Art. Now to maths business.
Evey kid in the class should have a shirt with a number. Most schools have a set of soccer, Aussie rules, basketball shirts or singlets. Or you can to choose one number each between 1 and, say, 25 or the size of the class. Students can draw the number on an A4 sheet and tape it to their chest. You can make two teams and score the game or just have some random fun. If you score a game appoint an official scorer. It’s good for their maths.
You can do +, – , X, / .
Friday Maths Madness 1: Put two kids from one team in the middle of both teams. Say 7 , 8. Then yell ADD. The answer has to run out to the middle. Or yell take away. Again the answer must run to the centre for the team to score. Make up the sums as you go along. Note: Madness increases when answers aren’t available. (1 Point for correct ‘running’ answer. )
Friday Maths Madness 2: This time the answer is in the middle of the two teams. Again call out add … the first two numbers to run out get a point each. Repeat. You can also yell take away etc. (1 Point for each correct answer)
Friday Maths Madness 3: Now everyone in a team has to form an even number with another student. This should work like musical chairs. There may be one odd student. Then they have to form odd numbers with a pair. ( 1 point for each pair.)
Friday Maths Madness 4: This is about times tables. Line up the teams. Call out for all… 3 times tables numbers to go in the middle. Repeat for 2, 4, 5 etc. ( 1 point for each team with correct answers in numerical order)
Friday Maths Madness 5: This is a time trial. Ask teams to form a line from the lowest to the highest number. Then yell ready set go. You can do this for evens only, odds only. (5 points for correct numerical lines.)
Friday Maths Madness 6: Ask each team to send out the numbers that they think add up to your age!!!! That should be entertaining. Tell them you are going to take away lots of points if they make you too old or too young. Ham it up!!!!!!
