Bootstrap is open source https://www.bootstrapworld.org https://www.bootstrapworld.org as in you can print off the work books or use pyret which runs in a browser with no install. Functional style programming of math for kids they successfully run in many state schools. You can even email Shriram if you wanted to ask him questions about the curriculum he will probably answer. He specializes in education https://cs.brown.edu/~sk/Publications/Papers/Published/ https://cs.brown.edu/~sk/Publications/Papers/Published/ Wildberger has elementary and grade 9 Australian math curriculum too in his channel https://m.youtube.com/user/njwildberger/playlists?view=50&sort=dd&shelf_id=8 https://m.youtube.com/user/njwildberger/playlists?view=50&so... but with some advanced math thrown in sometimes. Needs someone to teach it though, like hiring a local grad student or yourself. Foreign countries like Australia or Canada may have open curriculums for elementary http://www.edu.gov.on.ca/eng/curriculum/elementary/grade4.html http://www.edu.gov.on.ca/eng/curriculum/elementary/grade4.ht...
