**You Can**

We’re often told we can’t do maths, that we’re not good at it or that maths is for nerds. That cannot be further from the truth. **Everyone of us can do maths** – it is a fact! Watch this video full of scientific evidence to support this claim – video by Jo Boaler.

**Can You?**

I absolutely believe you can do maths, so I would like to challenge you to go up to level 2 – the level required for many jobs and courses.

**Are you ready for the challenge? **
