It is very much needed to improve the mathematics knowledge of primary teachers. Are there any online platform to use for improving concepts of mathematics for primary teachers.
You can refer below link, which has links to many other sites.
We have seen a concept called "Ganithagara" operating in some schools with nice tool sets. But those are not online tools.
Thanks for sharing..
This is very good and interactive site for education.Primary Students can learn basics of Mathematics interactively
