🍎 Welcome to iMath

Kids tap their own face on the class grid and type a 4-digit PIN. A brand-new student taps First time here? and makes a player in under a minute — nickname and a face, nothing else.

New players pick one of eight cube colors. That cube is how they walk around the island, and it is the first thing on the whole site that belongs to them.

Axel, the island's resident axolotl genius, introduces himself, explains that the island is a carnival of math games with booths that open as you play, points at the Test Your Strength tower, and hands the child off to the warm-up. A skip link is on every screen for the kid who has seen it before.

The child types five numbers as fast as they can. The app measures milliseconds per digit and stores that as their personal typing baseline.

Why it matters: fluency here means speed of recall, so the engine has to know how much of a child's answer time was thumbs and how much was thinking. Every later "was that fast?" judgement adds their own typing overhead back in — a slow typist is never mistaken for a slow mathematician.

The placement test is a carnival high striker — "Test Your Strengths." Each swing of the mallet is one math fact; ringing the bell means the child has cleared a skill band. It searches five bands, and it does not march up them in order:

• Add & subtract — the basics
• Add & subtract — the big ones
• Times tables — 0s, 1s, 2s and 10s
• Times tables — 3s, 4s and 5s
• Times & divide — 6s to 12s

Two quick correct answers clear a band and the test jumps upward; two misses drop it back down. It is a binary search, capped at fifteen questions, so most students finish in about two minutes regardless of level.

Two design promises to tell your class: one slow-but-correct answer never counts against them — a distracted moment is not evidence. And "don't know — skip" is scored exactly like a wrong answer, no worse, so there is nothing to gain by guessing and nothing to fear in skipping.

Clearing a band credits every fact underneath it. A strong student never grinds 1+1, and a student who is still shaky on their tables never opens the app on 7×8.

Credited is not mastered. Everything the assessment credits starts as practicing — it still has to be answered quickly, several times, inside the games before the engine calls it fluent. Placement sets the starting line, not the grade.

A carnival midway the student walks around with arrow keys, WASD, or by tapping the ground. Booths are the games; Axel's School is one-on-one coaching on a fact family they keep missing; the tower is always there for a re-test.

Sky Hopper and Critter Garden are open on day one. The other five booths are padlocked and cost a key — which is where the daily goal comes in.

Three platforms are live at once, each labelled with a fact. Answer one and the frog hops up to it. A wall of fog rises from below the whole time; if it catches you, the climb ends.

The loss condition is announced before the game starts, and the card closes with the promise that makes the whole thing safe: "If the fog catches you, the climb ends — but everything you learn is saved." No lives, no strikes, no lost progress.

No timer, no chase. Every correct answer grows a flower, and flowers bring visitors: Shelly the snail at 4, Dot the ladybug at 8, Flit the butterfly at 12, Buzz at 16, and Plume at 20 — which throws the Garden Party.

The Garden Party tracker is the point: a child who finds Sky Hopper stressful gets the identical fluency engine wrapped in something that only ever accumulates. Every classroom needs both temperaments available.

One tab per student, five summary numbers, and a fact family map — one cell per family, colored fluent / practicing / learning / not started / needs help. Below it, "Needs a hand" lists the families a student has missed three times running, each with the strategy hint to try one-on-one.

Per-student controls sit at the bottom: switch their fact set (full ladder, add–subtract only, multiply–divide only), unlock all games, reset progress, or remove the student entirely.
