Description

Built to top up, not to start from scratch

Unlike a typical themed set, this expansion pack comes without a fixed model to build. Instead, its 604 pieces and 104 unique parts add beams, axles, connectors and gears that top up a SPIKE Prime core set for bigger or more complex builds. Classrooms that have already worked through the core set and started running short on connector pieces or structural elements will find this expansion covers exactly the parts that tend to run out first during group robotics projects. This is particularly noticeable when several groups are building larger models side by side in the same lesson.

A colour palette built for Technic-style building

Black, yellow, blue and light bluish grey give the set a distinctly technical look compared with the bright palettes used in themed play sets. Black and light bluish grey form the structural backbone of most builds, while yellow and blue mark moving parts or connection points, making them easier to spot at a glance. For teachers managing shared class sets, this colour logic also helps pupils sort and return pieces correctly after group sessions.

Where it fits in a robotics curriculum

This set is aimed at schools and learning groups already using SPIKE Prime who need more building material for larger class projects, such as several pupils working on bigger robot models at once. Since it contains no motors, sensors or hub, it functions purely as a mechanical top-up rather than a starting point, so it isn't suitable as a first purchase for anyone new to SPIKE Prime or robotics in general.

Checking the parts list before ordering

The parts list on this page breaks down all 104 unique elements individually, including exactly how many of each piece the set contains. That makes it easier for teachers to identify missing pieces from damaged or incomplete class sets without reordering the whole expansion pack. Anyone planning their own SPIKE Prime builds can also use the list to check which connectors and colours are available before relying on them in a design.
