What we believe

Children shouldn’t just use technology. They should understand it, build with it, and shape what comes next.

  1. 01

    Think clearly.

    Break problems down, predict, then check ideas against real results.

  2. 02

    Make ideas real.

    From stories and games to data tools, children design, build, test and improve.

  3. 03

    Judge wisely.

    Know where data comes from, question what AI says, and protect their privacy.

The curriculum

Four stages. One path from picture cards to real apps.

Each stage has four series of twelve lessons, and every series ends in a project children can show and explain. Ages are a guide: we place each child by experience and ability.

Lum, Trelum’s mascot, explaining

Learning with Lum

One learning loop, from age 5 to 15.

Lum is the “l” in trelum, stepped out of our logo: curious, happy to try and never afraid of a mistake. In every lesson, Lum works through the same four steps with children.

Meet Lum
  1. 01

    Think.

    Understand the problem, break it into parts, predict what will happen.

  2. 02

    Build.

    Turn the plan into something real: picture cards, blocks or code.

  3. 03

    Test.

    Check the idea against real results. Find the bug, fix it, check again.

  4. 04

    Explain.

    Say what it does, why it works, and where its limits are.

Growth you can see. Every skill moves through three levels, shown in projects, plans and explanations.

  1. Guided
  2. Independent
  3. Transfer

What children make

Real projects. Work that runs, and that they can explain.

One signature project per stage, shown as illustrative mock-ups of course projects.

One curriculum, two places to learn

Learned together in class. Made their own at home.

The teacher presents each lesson on the classroom screen, then releases a matching activity that children practise at home and make their own.

In class · Classroom EditionThe teacher projects. The whole class thinks together.
  • No student devices needed
  • Fullscreen & narration
At home · Home StudioThe same idea, practised and made their own.

    Work is shared with a teacher only when the child submits it.

  • No public galleries

    No public profiles, social feeds or messaging between children.

  • Minimal data

    Nicknames where possible. No child email or birthday required.

  • No ads, no tricks

    No advertising and nothing designed to keep children hooked.
