We love maths and love Sumblox even more! SumBlox is a revolution in early Mathematics that grows with your child. Height of the blocks corresponds to the value of the numbers. Works for Addition, Subtraction, Multiplication, Fractions - some teachers are even teaching Year 6 Algebra in Australia with them.

*Due to its weight, this product has an additional shipping charge of $15 per item added irrespective of any free shipping offer.

Sumblox was invented by David Skaggs as a way to envision numbers the way he did when doing arithmetic in his head.  David imagines combinations of numbers with actual height value and then stacks those numbers to find the sum. He says "I am obsessed with combining numbers to create 10, something that helps break down problems quickly. After examining these aspects I realised that the skills involved in simplifying problems were all based on stacking numbers and understanding how they relate to each other. Taking these concepts and applying them to a stacking game seemed to fit building blocks extremely well".
