Get help with Mathematics, Grade 4
Most tutoring makes your child sit through material your child already knows. MapleMind flips that: pick the exact skill that's causing trouble — any of the 34 below — and the tutor teaches just that one, step by step, as many times as it takes. Ask questions in plain words, any time of day, in English, French, or 12 other languages.

How MapleMind teaches Mathematics, Grade 4 — every unit, lesson, and skill
Every skill below runs as a short session: a plain-words lesson, a worked example, solving it together, then a five-question skill check that earns up to three stars. Guided Mode keeps it teaching instead of answer-handing — turning it off needs a parent's password.
