Socratic tutor
What do you think the first step is for 12+13\frac{1}{2}+\frac{1}{3}?
Add the tops? So 2/5?
Good thinking — let's test it. Can halves and thirds be added directly, or do the pieces need to be the same size first?

How NumberSense works

Three simple steps, then a calm daily loop. We reward mastery, not speed.

1

Diagnose the gaps

A short adaptive check finds what's really missing — by prerequisite, not just grade.

2

Follow a mastery plan

Skills unlock in the right order. Each day: one lesson, a little practice, quick review.

3

Practice & prove it

Mastery checks confirm understanding; the Socratic tutor helps without giving answers.

Adaptive diagnostic

A short, smart check finds the real gaps — then reorders the path so foundations come first.

Mastery-first plan

Prerequisite-aware learning. Skills unlock only once the ideas beneath them are solid.

Socratic AI tutor

Never hands over the answer. It asks the next good question and diagnoses misconceptions.

Spaced review

Flashcards and 7-day retention checks keep mastered skills from slipping away.

Parent visibility

See gaps closed, time on task, tutor logs, and what's coming next — every week.

Calm, accessible

Mobile-first, WCAG-minded, high-contrast and dyslexia-friendly options built in.

Safe for kids, built for parents

No ads, ever

We never show ads and we never sell your family's data.

Math-only tutor

The AI tutor only talks about math and stays on-topic. Off-topic or unsafe messages are declined.

Full transparency

Parents can read every tutor conversation, any time, in the parent dashboard.

Built with COPPA in mind

Parents create the account and give consent; children only need a first name or nickname.
