Thinking clearly

How do I teach logic and critical thinking at home?

Teach critical thinking at home by asking "how do you know?" often, using puzzles and strategy games with young children, and moving to formal logic, arguments and common fallacies in the teen years.

Skip to signing up ↓

Young children

Sorting, patterns, logic puzzles, chess and strategy games. Ask them to explain an answer, not just give it.

Middle grades

Compare two sources on the same event. Spot what is fact and what is opinion in an advert. Ask what evidence would change their mind.

Teens

Formal logic: premises, conclusions, valid and sound arguments, and fallacies. Clareza's Philosophy and Logic course, a one-semester Grade 12 course, covers validity, soundness and fallacies.

What this is not

  • Clareza has no separate logic course for younger grades.
  • Philosophy and Logic is one semester, not a full year.
  • It is mostly on screen; games and discussion at the table are still yours.

Before your child starts: what we collect and why

We collect only what it takes to teach your child: the first name and sign-in you choose, their answers and progress, and their chat with Clara (written by Anthropic's AI, read aloud by OpenAI). Nobody trains AI on it or sells it, and you can see or delete it any time. You create your child's account yourself. Paying by card is how you give consent.

Read what we collect and why

Your consent is needed before we collect anything from your child, and we collect nothing without it. You create your child's account yourself; they never sign up alone.

  • What we collect from your child: the first name and sign-in you choose, their answers, time on lessons and progress, and their chat with Clara. Used to run the lessons, build their transcript and show you how they are doing.
  • Who else handles it: Anthropic (an AI company) receives the chat text and the lesson, with your child's first name but no last name or account details, to write Clara's replies. That is how Clara works, so it is part of the service. If you switch on answering out loud for a child, their voice is turned into text on our own server and then discarded; it is never sent to another company. OpenAI turns lesson text and Clara's replies (which can include your child's first name) into the read-aloud voice. Our email provider sends you reports about your child. Nobody trains AI on your child's data, and nobody sells it.
  • Your rights: see everything collected from your child, have it deleted, or stop further collection at any time, from your account or by emailingour support address. If you refuse the AI sharing above, Clara cannot teach, so the service cannot run. Chats are deleted after 30 days.
  • Safety: if your child writes something suggesting they may be hurt or in danger, we email you and Clareza's owner the same day.

Paying by card is how you give consent. Full details, including how long we keep each thing: Privacy Policy (version 2026-10-05).
