What fraction is at the dot?

Your answer, as a fraction

A parent would see:nothing yet

From the practice engine, checked by code in this browser. Nothing is saved.

For parents: what really happened

You see what happened: on their own, with help, or not yet. A skill counts as proved only after two checks with no help, at least 6 days apart, each with 4 of 5 right.

What a parent sees from the problem above
On their own

With help

Not yet

Answer the problem at the top of the page and it shows up here, the way a parent sees it.

Proved: not yet. That takes two checks on different days.

What you see for each child

  • Today's plan and what's done
  • What they got right on their own, with help, and not yet
  • Which skills are proved, and which checks are waiting
  • Tests and homework coming up at school
  • Every conversation with the tutor
  • Your notes, and dated records you can print

How it works

Every part of KaizenEDU reads and writes one record of what your child actually did. Here is the problem from the top of the page, as each part sees it.

Practice checked by code

The code that just checked your answer checks every answer. It accepts any honest way of writing it, and it never guesses.

6/8Right, the same amount

A tutor that teaches instead of answering

It asks one question at a time, gives the next hint, or works a similar problem. It never sees the answer key.

Child
I don't get it.
Tutor
Let's look at it together. How many equal parts are between 0 and 1?
Child
Can you just tell me the answer?
Tutor
Give it one try first, even a guess. Then I'll show you how.
Its replies to the problem above, word for word: hints, a first step, a worked example. Open conversation about anything is coming.
A calendar that plans test prep
Type the date, paste the syllabus or link the class calendar. Prep for each test lands on the plan for the three days before.
Real sources, named and linked
When there's more to watch, read or try, it's a free source with its name on it. We link to it; we never copy it.Fractions: Intro · University of Colorado Boulder (PhET) (opens in a new tab)Fractions as numbers (grade 3, family materials) · Illustrative Mathematics (opens in a new tab)

Where things stand

It's new. No families outside our team have used it yet, so there are no reviews, results or user numbers on this page. Here is what works today, and what doesn't yet.

What it asks of you

A few minutes to set up: your account, then each child's name, grade and language. After that, look in when you want to. There are no streaks, points or reminders for your child.

Privacy, plainly

Everything is saved in this browser, on this device, and nothing syncs between devices yet. Your child's name stays here. When the tutor uses AI, what they type goes through our server to Anthropic, without their name. No ads, no trackers. The microphone and camera work only after a grown-up turns them on.
