Counting…
Who signs up. A parent or teacher signs up with the child's first name and reads the problem aloud.
What a proof looks like. A level 1 pattern or counting problem. The child points; the adult taps the answer the child chose.
What a witness says. "I watched you find what comes next in that pattern. I see a math person."
The next step. A second family of problems the same week, so it is more than one lucky answer.
Start here: one problem
A first name or nickname is all we ask for. No email, no last name, no birthday. For a child under 13, a parent or teacher signs up and sits beside them.

Questions people ask
Problem solver program?
Free, no email, no last names. A first name and one solved problem is the whole sign-up. Every claim here starts with a solved problem the server graded. The label comes after the work, never before it.
Why can't I claim it right away?
Because in the national data a claim with nothing behind it does not move anything. Here the claim unlocks after one graded proof and one witness, so the sentence means what it says.
What do I get for sharing my link?
2 points for each new person who opens it, 40 when someone joins through it and solves their own proof, 20, 10, 5, 2.5 and 1.25 for the generations below them, and 20 more when someone you brought in reaches their own claim. The Share badges run from 1 recruit to 81 and from a chain 2 deep to 13 deep.
Does it cost anything?
No. There is nothing to buy, and no badge, rank or point can be bought. A purchase never fires a trigger.
What do you collect about my child?
A first name or nickname, a role, a language and, if you choose, a county. No email, no last name, no birthday. For a child under 13 the adult signs up and sits beside them.
