If math has felt hard, start here
Every skill on this page teaches the way a good teacher does — one small step at a time, with pictures that show the mathematics:
1 · Learn
Watch the idea unfold with a narrated picture. Replay any step as often as you like.
2 · Guided practice
Try a few with hints one tap away. Best when the idea still feels new.
3 · Independent practice
Work on your own, with feedback after every check.
4 · Quick check
Test-style: no hints until you answer — so test day feels familiar.
