At SumBlox we believe learning should be fun, and games should be challenging and interactive. That's why we worked hard to develop an extensive learning support system to support you and your children or students so that you can get the most out of your time playing with our blocks. 

The best teaching methods can vary depending on the teacher and the students, but we believe there is no single 'silver bullet' to solve all educational hurdles. Whether the learning environment is 'teacher-centred' or 'student-centred', if the methods are considered high or low-tech, the goal is the same. These activities are designed to develop academic knowledge through a series of games and challenges, that can be enjoyed by educators and students alike.

One of the best things we ever bought!

I was totally expecting these to be very loved. We had the original Sumblox first but these are just next level amazing. Better size for little hands, easier to store, grippier and on a 10cm scale. They have been used daily since we got them to build towers, to count, to knock down, you name it. Brilliant concept that can be used for years as a desk resource for learning math concepts. The cards are awesome as well for quiet time while younger sister is asleep. Amazing quality and fun to play with for adults too :) I seriously could not be happier about it!

Great number play!

We love our new smaller sumblox. They fit kids hands so beautifully and really promote number play. They are using the cards to create patterns, animals and learning to copy and problem solve. Beautiful quality and so many great instruction cards. Thank you!

Great item

The thing I love most about this is that it appeals to both my five year old and my almost 12 year old. The activity cards are really great and my kids have been enjoying using them.


Love these as much as our larger set. Kids love using them for maths practise, as well as just for building. Perfect size for holiday travel too.

Would definitely recommend

I would buy these again any day. Simple, beautiful, but most importantly they demonstrably help with numeracy. My six year old is able to grasp mathematic concepts so much faster using these blocks. I’m really impressed with them and they’ve helped her enjoy maths.

Unbelievably amazing. Quality and precision.

Great products. Shipping is always prompt and delivery time super quick. Always happy with this supplier. Prices may seem high but definitely worth every cent. You literally get what you pay for. My son has had a few sets for years now and they look brand new. These sets are NOT mass produced Chinese crap made of pine, these are precision pieces of art you will keep for years. I've spent hundreds on other toys that hold my sons attention for 15min and he gets bored, the open ended nature of these toys keep him entertained for literally days at a time. The flockmen provided 2 days straight, of contented play, before he remembered he had a new set of spinning tops as well, and decided he wanted to play with them for a while. Honestly the best value for money toys I have ever purchased for my son. He has had the rainbow set for 2 years and still enjoys playing with it. The different challenges and creations others have made and can be viewed on social media are a constant source of inspiration. As an adult I'm honestly amazed at how much I enjoyed playing and creating with these toys ( the stackable sets are my personal favourites) and how quickly Time goes by when my son and I are using these sets together. This numbers set has been very helpful in teaching my son basic addition and counting. I can't recommend these toys enough. They are literally amazing.


I purchased these to give my daughter for her 5th birthday but when they arrived I couldn’t resist getting them out. What an incredible, visual way to learn about numbers! Can be used for SO many different ways of teaching!
