# Learning By Topic KS2: Lego and Mathematics

Explore the different 3D shapes you are creating with your Lego, can you name some 3D shapes and list their proprieties (for example number of faces and vertices) Remember a single Lego brick is a cuboid with cylinders (the studs) on top!

How many lines of symmetry do your various Lego creations have?

Build a cuboid/rectangular prism using Lego bricks. Now find the area and perimeter of your model.

Measure your height in Lego bricks! Decide on a consistent sized brick for the measuring and estimate before carrying out the measurement. Now with a ruler/tape measure, record your measurements formally in metres and centimetres, using a decimal point. Top Tip: This can be done for family members and friends too.

Follow a set of instructions to put a Lego kit/set together. When you do this you enhance your problem solving skills which is a vital skill to have as a mathematician!

Create a Lego code for the alphabet (e.g. a =a 2 stud yellow brick, b= 4 stud blue brick) write/model your theme words using this code – can anyone crack your codes?!

Now ask an adult to write some addition, subtraction, multiplication and division sums in this code. Can you decode these and then solve them? You could use Lego bricks to help you with your multiplication and division.

Lego is a great tool to use when you are learning about fractions. Explore how many smaller sized Lego bricks can fit into larger bricks and record different fractions. See the following links for  examples:
