SumBlox: explore number relationships through visual/kinesthetic play

** This is not a sponsored post, I’m just super excited about this product and can’t wait to see what our students do with it!


What it is: Why yes, this is a technology blog. But no, this manipulative is not a technology product. I’m writing about SumBlox here anyway because technology led to the happy discovery of SumBlox and is a great reminder of why it is important to be a connected educator! I learned about SumBlox just a few weeks ago on Twitter as a share from ISTE from @michellek107 and @sumblox. This also isn’t a free tool (like I normally share), but I’m already so impressed by the brilliance of this tool, that I’m sharing it anyway!

SumBlox are a wooden block set of numbers 1-10. What makes those blocks and numbers super amazing: each block size corresponds to the number that it represents. (1 being the smallest and 10 the biggest). Even more super amazing, when the blocks are stacked, they represent the equivalent number. For example, when the 2 and 3 blocks are stacked, they are the same height as a 5 block! GENIUS!! These blocks are a visual and kinesthetic representation of our base-ten number system.

I purchased the Educational Set for our classrooms which comes with 100 solid hardwood blocks including: Thirty 1 blocks; twelve 2 blocks; eight each of the 3, 4, 5, 6, 7, 8, and 9 blocks; two 10 blocks and four teaching manuals. The purchase was right around the $300 mark with free shipping and a 10% discount with the code “sumfun.”

SumBlox- Explore number relationships through visual/kinesthetic play

How to use SumBlox in the classroom: These blocks allow students to visually represent and discover math relationships. Students can stack blocks to explore and visualize addition equations, if the stacks are the same height, they also have equivalent values. Students can stack multiples of a number to represent abstract math concepts like multiplication grouping or addens of ten. Students can also explore the concept of fractions and of the mathematics behind adding fractions with different denominators by stacking and scaling fractions. SumBlox also are a fantastic introduction to algebra concepts.

The educational set comes with 4 guides that lead you (the teacher) through exercises and lessons to do with your students. While these are extremely well done, because we are inquiry based, my excitement comes in seeing how students will explore these independently first. I’m excited to see students discover the number/size relationships and number patterns.

At Anastasis, we have a 1:1 iPad program. I anticipate that students will use these blocks for stop-motion animation projects as they explore (iMotion HD is the app they use), capture their discoveries of number relationships in their eportfolio (we use Evernote), and even in Explain Everything videos.

Tips: If you are an administrator purchasing these for your school, go ahead and purchase a few of the educator kits. I only purchased one and am already going back to order one for each classroom. These are going to be popular!

  1. SumBlox seem like an amazing visual tool for students to see the visual representation of numbers. I think it would be a great tool for primary classrooms since there is a lot of mental math in addition. I think that SumBlox would help students see the relationship between addition and subtraction which has been a current struggle in my classroom.

  2. Jaw dropping! Our Sumblox arrived this week and the kids have been discovering Maths just through play. My 3 year olds are now identify and order numbers 1-10 and my 4 year old is loving exploring all the addends of 10. Love, love, love this product!
