Free, no email, no last names. A first name and one solved problem is the whole sign-up.
Mathematical thinking shows up in patterns, equations, fractions, percents, logic and geometry. The proof problems here draw from all six.
For the youngest, the adult reads the problem aloud and the child points to the 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.
What the national data says
In 2012 NSF asked eleventh graders whether they agreed with “I see myself as a math person.” 44% did. In 2016, 43% of those who agreed were STEM majors, against 31% of those who disagreed.
Being seen counts as much as seeing it yourself: for “Others see me as a math person.” the figures are 43% and 30%. Test confidence is more common (65% have it) and weaker: 39% against 31%.
How it works
- Prove it. Pick a level from 1 to 5 and solve one problem. The server grades it. A wrong answer costs nothing and nobody sees it; the next problem is new.
- Get seen. You get a link. Send it to someone who has watched you work: a parent, a teacher, a coach, a friend. They open it, see your proof, and say “I see a math person.”
- Claim it. After a proof and a witness, the sentence is yours to say, and the badge with it.
- Pass it on. Everyone who opens your link is invited to prove their own. Each one who does is on your chain, and their chain is on yours.
Where the claim leads: twelve tracks
The claim is the front door. Behind it are the twelve STEM Farm tracks, each one starting from zero, each with a first mission and proof at every gate. Your own proofs pick the ones shown to you first.
By age
What you can earn
37 badges on 11 lines, 116 tiers in all, and seven ranks. None can be bought. Sharing more earns more, and rank still needs proof and witnesses, because the three lines are multiplied.

Questions people ask
Mathematical thinker program for preschoolers?
Free, no email, no last names. A first name and one solved problem is the whole sign-up. Mathematical thinking shows up in patterns, equations, fractions, percents, logic and geometry. The proof problems here draw from all six.
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.
