This page contains links to ideas for using LEGO® bricks to explore mathematical concepts. My aim, over time, is to create a list of 101 different activities related to mathematics and maths teaching. Each idea or concept is shown only using a picture, you should be able to work out how to introduce or use it for yourself – otherwise it wouldn’t be fun!

- Equivalent fractions 1
- Triangle numbers
- Square numbers as the sum of two triangle numbers
- Algebra – (a + b)
^{2}– Why is*ab*green? - Gauss’s EΥΡHKA! num = Δ + Δ + Δ
- Sierpinski Triangle in lexicographically ordered 4-argument AND
- Sum of infinite series 1 – Σ(½^n) → 1
- Sum of infinite series 1 – Σ(⅓^n) → ½
- Sum of infinite series 1 – Σ(¼^n) → ⅓
- Sum of odd numbers as square numbers
- Pythagoras’ Theorem
- Sierpinski carpet
- Box fractal
- Haferman carpet
- Cantor square fractal
- Cantor dust
- Sieve of Eratoshenes (unique prime factors)
- Multiplication tower
- Number bonds – arithmetic (1 – 5)
- Number bonds – multiplication (1 – 5)

Up to 11 now – I am especially pleased with the Pythagoras!

I have now added seven more images to the series: five of them are related to exploring fractals (compare with number 6), the other two are related to multiplication – identifying unique prime factors through the sieve of Eratosthenes, and a multiplication tower (for 1 – 5).

Next is the couple of images related to number bonds for arithmetic from 1 to 5. The multiplication version can also be related to equivalent fractions… for the more inventive amongst you!

Thanks for sharing, Colin! I featured your tower in the big gallery here: http://www.moebiusnoodles.com/2014/02/multiplicationtowers/
