A great product which is fun to use in multiple ways and learn with. The additional individual numbers available for purchase can extend learning.

My favourite yet.

The arrival of our sumblocks has been my favourite arrival so far. The quality is amazing and the things that you can do with them is endless!

Extra numbers = Extra Fun

I love being able to get some extra numbers to go with my 43 piece kit. This meant I had enough 2s to make 10, enough 3s to make 15 and enough 4s to make 20. Can’t wait to get an extra 10 when they are back in stock for friends of 20 work.

Necessary purchase

I recently purchased a set of sumblox which are used a lot in our house. Unfortunately the set only came with one ‘10’ block. This extra block is a necessary addition to the set to extend the learning.
