Alpha School · Math
Five grade-level guides. Each one walks a skill at a time — a question you can already answer, one new move, the rule, the trap it sets, then a short ladder of practice. Between the sections are mixed checks where nothing tells you which skill to use. That is the part a test is really testing, so they are the ones not to skip.
Every question is new. None of them is from a real test, and the numbers and stories have all been changed.
How to use a guide
Answer, press Check, then read the answer even when you were right — it shows the method, and where each wrong option comes from.
Your work is saved in your own browser, so you can close a guide and pick it up where you left off.
