Talk:World of Math - number of skills/@comment-25143095-20140913032512

What is strange though is that with these two recent new skills - I can't Master up with them. Meaning I practiced them but when I go to the 3rd Grade mission page or the 4th Grade mission page - I am not offered the Mastery challenge. It just says that I have practiced all of the skills and asks me if I want to practice something else.

Strange.
