Common questions

Frequently Asked Questions

Does Lumi only teach math?
No. Lumi is a full K–5 curriculum. Math is one of four core subjects alongside Reading & ELA, Science, and Social Studies. Kids rotate through all subjects during a school day session.
My child hates math. Will Lumi help?
Math anxiety often comes from drilling problems without understanding. Lumi always explains the concept first, uses visual emoji representations, and lets kids answer by tapping at their own pace rather than on a timer.
How does voice grading work for math?
Kids tap their answer or type the number, and Lumi grades it instantly.
Does Lumi cover math facts like times tables?
Yes. Multiplication facts are drilled through spaced repetition with character-led practice rounds. The app tracks which facts are solid and which need more work, cycling back to weak facts in future sessions.
What grade level math does Lumi teach up to?
Lumi covers math from Pre-K through 8th grade, with Lumi High for grades 9–12. Content is built around the grade-level skills Common Core describes and adjusts automatically based on the child's profile age and performance data.
