JuProDev turns real analytical thinking — spotting patterns, cracking hidden rules, making smart calls — into missions kids actually want to finish. Solve one right now →
3 for 3 — those are Observer-track missions in miniature. Ready to see where your kid would start?
Find their starting level →Kids don't outgrow JuProDev — they rank up through it. Each level mirrors a stage of real analytical work.
First up: Pattern Detective opens Level 01 — with packs built for every level to follow.
No apps to install, no lessons to prep, no printer required. However you open it, your kid is solving in two minutes.
Download the pack. Print it, open it on a tablet, or read it together from any screen.
Your kid works 7 detective-style missions, mostly solo — about 40 focused minutes.
The answer key gives you the check to run and what to notice in their answers — and which pack comes next.
Each pack reads like a case file, not homework. Your kid plays detective; the back pages tell you what each mission asks of them — and what to notice in their answers.
Your kids will grow up with AI that writes, codes, and calculates on demand. What it can't hand them: noticing what matters, asking the sharper question, weighing a call with no formula. Those are learned — and the best time to start is six, not twenty-six.
Patterns, details, differences — the raw material of every insight.
Sort, compare, form a hunch, test it. The structure under math and science.
Weigh tradeoffs and explain the "why." The skill every future runs on.
"Every day I'm paid to do what these packs teach — spot the pattern, ask the sharper question, make the call. Almost none of it was taught to me early. JuProDev exists to start sooner."Byron · Founder, JuProDev Data & analytics professional — 15+ years in the work, 20+ years fascinated by it
Four quick questions, answered by you — nothing is collected from your child, and your answers never leave this page.
Answer the age question and at least one more to see a result.
The moment each pack goes live, you hear first — plus occasional founder notes on raising sharp thinkers. One useful email at a time — leave whenever.
We only use your email for JuProDev updates, and we never collect information from children. See our privacy policy.
No problem — printing is one option, not a requirement. Packs open on any tablet or computer, and kids can mark them up with a stylus or finger using a free markup app. You can also work through a pack together on screen, answers out loud. Prefer paper? Any print shop or library runs a copy for a couple of dollars.
The system spans 6–12 across four levels, and the free placement above finds the right entry point. Level 01 (Pattern Detective) is built for 6–8; the upper levels are designed so a 12-year-old is doing genuinely challenging reasoning, not kid stuff.
Very little, on purpose. Kids work mostly independently; you read an instruction aloud if needed and check the answer key at the end. No prep, no lesson plan.
About 30–45 focused minutes, and it splits naturally into two or three short sittings. Stopping mid-pack is normal and fine.
Packs are single purchases — no subscription, no account, no ads. One purchase covers your whole household: every kid, as many runs as you need. And updates are free: if a pack is revised, you get the new file at no cost.
Packs launch on Teachers Pay Teachers and Etsy — the email list hears first when each one goes live. Every purchase comes with a household licence; classroom and group licences are available too.
