Everything in the last blog post is still in effect, except how students will be graded. Since the mastery challenges don’t seem to be popping up like I thought, here is the new grading scale:

Reach the “mastered” step: 105% (A+)
Reach the “Practiced” step: 100% (A+) – Get five in a row correct with no hints.
Reach the “Struggling” step: C (75%) – Get a few correct, not in a row.
Stay in the “Needs Practice” step: E (O%) – Do nothing.

If you can figure out how to get to the mastery challenge for each statistic strand, you can have that extra 5%. (Check under “subject”, “grade”, “7th”…)
Otherwise, just get 5 questions in a row correct in each strand, get to the “practiced” step, and receive 100%.
