Singapore maths is not taught in such convoluted way. It confounds more than it defines the concept, if singapore maths is taught by this fella!

dude.. if i am your student for singapore math, i won’t improve. I’m a singaporean math teacher and i think there are so much talk in your videos that you are getting the concepts across to people. Singaporean math teachers don’t talk as much as you do, yet the students get the concepts without getting bored.

Is it for 8 year old? Standard must be low now than decades ago. I was running my father’s shop on my own at thatage as well as top student in the school let alone finishing maths problems in minutes and correct fellowstudent’s work on behalf of my maths teacher.

The term “Singapore math” refers to the company publishing math books, not the math taught in Singapore. It has nothing to do with Singapore.

I am training my 4 yr old baby girl abacus, and she knows her counting till 1000. But when I showed her last night this video, she was so exited that she wanted to see it again, although she was so tired! Thank you! This is the first best thing since the educational Disney shows ðŸ™‚

hi mr khan

can you please tell me what it means if we had less then a unit

for example

\$1351.50 cents

you will 1 thousands
3 hundreds
50 tens
1 units

what do i call the remaining .50 cents?

do you have a video that explains what is less then a unit.

thank you

I’m 11, from Singapore too, but I’m great at Math, but I get careless sometimes so I want to see if I can solve some tough questions like I did to a Sec 1 question.

12. hyylo says:

@LegoWilly

i do not think that is correct.

you have 5 tens

you have 1 unit

what do i call .50 ?

What do i call something that is smaller then 1 unit.

Big thanks to @khanacademy ! I’d learnt Algebra, Trigonometry ! But my dMaths exam tomorrow contained Symmetry, Symmetry Properties of Circle and Angle Properties of Circle. But I’m still glad-ful I’d learnt something. (:

23. Damian Chia says:

You seriously draw out the marbles,haha!! I know this video is pretty old but modern tablet laptop would be easier to draw this.

this doesn’t seem different from anything i was taught as a child in the 70’s Â why is this unique. Â or is it that basic techniques are just being renamed and repackaged and presented as something new

25. andre jimenez says:

Amazing shooooooooooooooooooooooooooooooooow

u predicted common core before it was cool

28. Michael Toso says:

Try a drawing program like MS Paint with copy & paste & resize.
