A tutor that explains again
When an answer is wrong, your learner gets the step they missed explained a different way — not a red cross.
4th grade, fractions and first real essays
Fractions, long division, and writing that has to hold an idea for more than a paragraph — with practice that gets harder only when your learner is ready.

Frequently Asked Questions
What subjects does Koydo cover for 4th Grade?
5 areas: Math, Language Arts, Science, Social Studies, Art & Music. Each one is taught as short interactive activities with practice, explanations and progress tracking rather than a single video.
Is 4th Grade the right level for my child?
4th Grade on Koydo is written for ages 8-10. If your learner is ahead or behind, they can work in a neighbouring grade — the practice adapts to what they can already do, not to what year they are in.
How does a family get started?
A parent or guardian creates the account and adds each child. Account access, recovery and screen-time settings stay with the adult. Plans, prices and renewal terms are shown on the pricing page before anything is bought.
Can parents see what their child is doing?
Yes. The parent area shows progress per subject, recent activity and where a learner is struggling, so a five-minute conversation can be about the right thing.
