Khan Academy Addition

This is a very good website for online learning.
Khan Academy talks about the most difficult concepts to the very basic concept.

This is what he says about addition. The level of English used can be quite difficult for the students. Parents, if you are showing this, do take some time to explain to the child what he is talking about.

There are sums you can attempt, you just need a google account, log in and try to do the sums that are attached to the video. Just click on the "Do Exercise" on the task bar, login with your google account, and you can proceed from there.

Thanks.

Cheers and happy exploring!
