I teach quite a few foreign students at a U.S. university. Frequently students are placed in our most remedial math class due to not having placement scores and failing to test out of the course. I am trying to put together a list of resources for how our terminology compares to what they are used to. For example, I know many parts of the world use a comma as a decimal separator where the U.S. uses a decimal point. Other languages don't group things into groups of 1s, 10s, 100's of various units then such as 5 things and Latin America to U.S.
Does anyone know of any such resources already made? If not, other suggestions for how other countries do and represent things differently in primary/secondary mathematics would be helpful for me to put together my own tutorial for incoming students.
