So I went back to Khan Academy to see what color they used for their layout,(and now I realize the answer to my question: what shade of blue will be pretty but not too dark to see white text? is … right here on my blog…)
I now, on this second day, can do a “mastery challenge.” It actually makes sense that I can’t “master” something on the same session that I learned it in. Yay! I don’t know if the 15:??.?? countdown timer was for hours or minutes (I do hope hours) … yes, *everything* is all exciting and counting down and adding up.
I was told this was my chance to show mastery in these skills I’d already practiced. However, not one of the questions was for a skill I’d already practiced. They were about fractions and decimals. My “practice” session was whole number operations.
It’s okay, though. He wants to help us learn!
Now, I’ve “mastered” a bunch of skills, having answered one whole question correctly (from a randomly generated question, so the challenge level was … random.)
And more importantly, *if* I can stop being distracted, I’ve got a color combination 🙂
