Connect-Bangladesh link
This is mostly for my own reference, but I just discovered a web site called Connect-Bangladesh. This is an American-based relief organisation which aims to provide educational support for schools in developing countries. A worthy aim, but I’m extra-interested in their Bangla page, which has various sections on cardinal numbers, body parts, days and seasons, and the alphabet.
Unlike other Bangla resources I’ve found on the web, this site includes graphics of the Bangla script, though their transliterations seem to use the somewhat-unhelpful Hindi schema.
