Fun for years to come

The number nerd in me was probably much more excited receiving our SumBlox than my daughter (not yet 1) but I can see she will enjoy them for years to come. Currently the larger numbers are beautiful wooden objects for her to explore shape, sound and space. As a mathematics teacher I am looking forward to watching her learn basic number and sum recognition with them as she grows and plays.

Making Maths Fun

I couldn’t rate these more highly as a teacher or parent. We have used these so much in so many ways. They are such an amazing product. So clever, so versatile.

We bought these with our sons NDIS funding to help get him school ready. The are great! Such an open ended toy and great quality! Even the speech therapist loved them!


Beautiful as always.
Thank you!

Fun with numbers

Both my boys (1&3) love them. The math component will come in time, meanwhile they are great as stacking blocks and matching games. I am always looking for toys that last. I am sure SumBlox will last a very long time. Great investment and beautiful product.

Bambie Lee

Definitely a high quality finish- very satisfying and comfortable to hold and build with!

Morgan Family

Love these sum blocks they are great for all ages and beautifully made. My children have played with them every day since they arrived.

Jodie D

Simply an amazing addition to our play! Within hours my 5yo had grasped the concept of addition, and was doing math equations. His kinder teachers were amazed at what he had learnt in the covid break from these! My 2yo also loves to play with them, stacking towers, number identification, and even starting to grasp basic number concepts as well. I highly recommend

Mandeep Narayan

Bought this for our daughter who’s just learning numbers. Just by using this she has learned her numbers so quickly! And through fun play. An awesome tool which I’m sure will keep on giving as she learns about math.
