At first glance, the Grimm's World of Numbers can look like a group of separate toys in a rainbow colour scheme, rather than something designed to help children learn numbers. Only when you look a little closer does the system reveal itself.

The Grimm's World of Numbers collection is one of those that feels truly underrated, and that's probably because many people aren't aware of it! 

Here at Babipur we've sorted every Grimm's World of Numbers toy into one collection on the website, so you can explore these wonderful maths toys easily. If you're one of the ones not quite in the know about this range, read on to learn about the brilliance that is Grimm's World of Numbers. 

What is the Grimm's World of Numbers? 

In this collection from Grimm's Spiel und Holz Design, each number from 1 to 10 has its own colour, and those colours appear again across different toys in the range, from the Counting Rainbow and Counting Stack Game to the Concentric Circles & Rings and more. That means children aren’t just using one toy at a time; they’re coming across the same values again and again in different forms, building familiarity without needing it to be explained.

Eight different toys are officially part of this colour-coded collection, as well as one matching art print, although I've also added the Large Conical Tower and the Wankel Tower to the collection as they follow the same colour scheme and can be used alongside the 'official' range. This isn't to say that you need to buy all eight; in fact, you can buy just one and still achieve the intended learning and play value. However, the colour-coding of these toys makes them great for using together, building a relationship between colours and numbers that makes learning a lot easier. 

The Colour Code

Each number in this system has its own colour, one is teal, two is green, three is a lighter green, and the colours move through yellows and oranges into reds, before going deeper into maroon, indigo, and blue for ten.

These colours aren’t random. The colour palette has the kind of harmony often associated with Waldorf materials. They follow a sequence that feels consistent when you see it in use, with each colour sitting naturally alongside the next. The number line starts to feel like a progression rather than a set of separate steps, supporting early ideas of order, scale, and relationship.

Where Maths Starts to Show

A child matches the same colour across different toys, picks out the same colour again later, lines pieces up by size, or builds with them, without needing to be shown how or to count everything out loud. A number might appear as a bead, a block, a figure, or part of a rainbow, but it still feels familiar.

This is where early maths starts, in noticing more and less, bigger and smaller, what comes next, and how things relate to each other.

You don't need the full range for the Grimm's World of Numbers system to work. Even a single toy introduces the same colour-coded logic. But when sets are used together, the connections become easier to see over time, with the same values appearing across rainbows, blocks, beads, figures, and numbers.

That's exactly why we have grouped the full collection together at Babipur, so it’s easier to see how it all connects.
