Start with the foundation. Learn the key idea, important vocabulary, and why the skill matters before you practice it.
Build the skill in stages. Use guided examples first, then apply the idea with less support and explain your reasoning.
Use feedback to improve, not just to finish. Check the explanation, identify what went wrong, and try the reasoning again.
Finish with a mastery challenge. Your score and responses are saved for your teacher, but mastery also means you can explain and use the idea in a new situation.
These curriculum areas are being built into the same pathway system. They are not student-ready yet, so unfinished lessons stay hidden until they actually work.
Choose a pathway to begin. Your progress and final score will be saved when you finish.
