SumBlox Originals Basic Set 47 Pieces

by SumBlox

Learning through play at its best! Never before has this sentence been more accurate than here. The SumBlox Building Blocks Basic Set 47 Pieces from Oskar's Wooden Ark teaches kids mathematics as they play. The higher the number, the taller the block. No matter how you stack them, if the numbers add up, the heights will match.

SumBlox are a multi-sensory maths tool that allows students to visualise the value of numbers through height, making primary maths concepts (addition to fractions) significantly easier to understand and remember. These blocks are made from high quality, solid hardwood and come with lessons and activities that teach through games. It works for Addition and Subtraction, Multiplication, Fractions, adding Fractions and some teachers are even teaching Year 6 Algebra.

SumBlox allow kids to explore and discover maths on their own terms through an engaging hands-on play activity that they already enjoy – playing with blocks.

SumBlox are a math manipulative, building block set, and a discovery toy for any child to naturally learn mathematics and its properties through play.

SumBlox can be played with in many ways, foster many skills sets and can be used for learning activities even before a child understands the concept of numbers and their value. Click here for play and learn activity ideas for children of different ages.

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.

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.

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.

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.

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.
