I wasted enough time trying to find a clean and simple teaching aid to teach Tamil and English alphabets to my son. What ever I could mange to find was too clumsy and complex for kids. Instead of wasting time I made two documents to teach Tamil and English alphabets. The goal to keep it simple and reduce clutter and associate a well known image to each alphabets.
It is interesting to note that even the printed books are no different, they are too complex and way to distractive for kids.
Now all do is now show the pdf files in full screen mode and let the kid ponder over what is there on screen.

Ya I have an idea for your problem. That is you can use tamil apps for teach tamil letters to your kids. It includes audio and video format to describe and teach tamil alphabets. It helps your kids to learn tamil alphabets and time consuming. This is an easy method to teach.
Interesting and very useful to children
