Description

A top-up pack for the classroom

Unlike a typical themed set, this pack is designed as a replacement pack: it tops up or replaces parts from existing Educational sets covering computer science and artificial intelligence for grades K to 2. With 201 pieces, it provides enough material to restock several learning groups without buying a whole new set, which is a practical saving for schools working with tight budgets. That keeps lessons running smoothly even when materials see heavy classroom use, without a group having to pause for missing parts.

Four minifigures for the classroom

Despite the technical focus, the pack includes four minifigures. They let classroom projects be personalised with small characters, which makes programming and AI concepts more approachable and playful for younger children working through the curriculum, turning an abstract subject into something they can point at and handle. In early lessons, figures like these help turn technical steps into a small, followable story, and four of them make it easy to split a class into small groups.

49 elements in white, turquoise, orange and coral

With 49 different elements in white, dark turquoise, bright light orange and coral, the palette is strikingly friendly and easy to tell apart. That helps both teachers and children quickly recognise individual pieces when following instructions or learning tasks, which keeps lessons moving without long searches for the right brick and cuts down on mix-ups between similar parts. In larger classes, that clear distinction pays off when sorting and tidying pieces away after the lesson.

The parts list for classroom use

This page lists all 49 elements with their colours, which is especially useful for schools wanting to reorder specific missing or worn parts from their Educational stock instead of buying a whole new set, keeping a classroom's materials topped up across several school years. That saves both budget and storage space over time, a noticeable benefit for schools with limited room.
