CountCraft
Prove it with tiles. Count the same shape two different ways and watch a maths fact become obvious — no algebra needed to see it is true. Build the staircase, grow the square, cut the square. On-device, nothing leaves your phone.

Meet the cast
CountCraft's Counting Crew each embody one combinatorial-proof method through a recurring defining act — the character IS the method. Surfaced at session boundaries; Proof Director Quill coaches build-the-two-counts-then-read-the-identity, and never proves for the kid.
Tallis
The Two-Ways Counter — counts the same collection along rows, then along columns, and insists the two totals be equal (double counting)

Bijou
The Pair-Matcher — draws a one-to-one pairing between two sets to prove they are exactly the same size (bijection)
Read chapter →
Stacia
The Staircase-Mirror — mirrors a one-two-three staircase against itself to make a rectangle (triangular numbers)
Read chapter →
Nona
The Gnomon-Grower — adds the next odd L-shaped layer to grow a square one ring at a time (perfect squares)
Read chapter →
Arel
The Square-Cutter — cuts a square into four rectangles to read off a-squared plus two-a-b plus b-squared (area model)
Read chapter →
Domina
The Domino-Tiler — tiles a strip with squares and dominoes and counts the number of ways (Fibonacci tilings)
Read chapter →
Chessa
The Handshake-Counter — pairs everyone with everyone exactly once to count the handshakes (choose two)
Read chapter →
Cammy
The Committee-Splitter — sorts every committee by whether the last person is in or out (Pascal's rule)
Read chapter →
Sett
The Subset-Flipper — flips an in-or-out coin for each item to list every subset exactly once (two-to-the-n)
Read chapter →
Parry
The Parity-Prover — two-colours a board to show when a tiling simply cannot exist (parity and impossibility)
Read chapter →
Quill
The Proof Director (mentor) — a warm, attentive adult who coaches build-the-two-counts-then-read-the-identity, and never proves for the kid

Learning goal
Prove it with tiles. Count the same shape two different ways and watch a maths fact become obvious — no algebra needed to see it is true. Build the staircase, grow the square, cut the square. On-device, nothing leaves your phone.
Question kits
16 curriculum-aligned kits × 25 questions = 400 questions per app, mapped to recognized standards.
On-device AI mentor
FoundationModels-powered hints, feedback, and adaptive difficulty — all running locally.
Mentored by Quill — on-device AI, no data leaves the device.
How CountCraft handles your kid's data
