Hi @Matthew_Rama, the good folks at PhET are now able to support translating some of their simulations into Lakota. As you probably recall, these are the fun science and math simulations we looked at. You can access them all via the website: https://phet.colorado.edu/, or via their Apple or Android apps ($.99).
They’ve asked that you provide a list (up to 10 or so) of the simulations you’d first like to translate. Here are the sims aimed at elementary school age: https://phet.colorado.edu/en/simulations/category/by-level/elementary-school (any of those with the orange “5” HTML5 badge), and here is the complete list: https://phet.colorado.edu/en/simulations/category/html
The text in these is pretty minimal, and PhET has their own simple translation interface, so it might be easy to pull someone else in to work with @Peter_Hill.
