**Geometric Chalk Designs:**

Ask the following mathematical questions when you are admiring your work:

- How many sections do we have in total?
- How many parts are pink?
- What colour is the most common? How many?
- Which section has the largest/smallest area?
- Which section has the largest perimeter? How can we be sure?
- What fraction of the design is green?
- What percentage of the design in blue?
- What is the fewest number of colours you can use so that no adjacent sections are the same colour? Can you create a design that requires more colours than your original one?

**MAZES:**

A maze is great fun and it can be a maths learning experience too!

Mazes offer open ended problem solving for all ages in an imaginative and creative environment. They help people develop mathematical logic skills and require participants to memorise lengthy sequences of moves in a particular order.

**Jumping Julia**

Help Julia get from start to finish. The number on each square indicates how far you can move. You may jump horizontally or vertically, but not diagonally.

Get the students to design the 5 x 5 square grid:

- discuss the properties of squares – the four sides of the squares should be of equal length.
- Decide on the length of each small numbered square. Then multiply this number by 5 to calculate the length of the overall 5 x 5 grid.
- Students should familiarise themselves with the equipment used to measure length – decide on appropriate units to use and measure out the required dimensions.

There are a great range of mathematical mazes. The maze designer Adrian Fisher has created 6 minute mazes – a set of interesting logic mazes used on the streets during **Maths Week. **
