Maddy finds out about dyslexia
The UK's biggest dyslexia charity, Xtraordinary People wants more done to help teachers spot the signs of dyslexia in their pupils.
Dyslexia affects part of your brain and can make reading, writing and spelling really hard work.
About one in 10 kids have dyslexia, and it can be worse for some than others - words can look blurry or jumbled up, or it can be hard to get dates in order.
It says dyslexics have huge strengths, just a different way of thinking.
Eleven-year-old Cameron is one of several kids with dyslexia at his school and told Newsround he didn't really know what it meant at first.
"I thought I was dumb, but then I learnt it doesn't mean that, it just means your brain works in a different way to other peoples'."
Cameron's school offers extra one-to-one support, which he says really helps and has showed him he can still achieve anything he wants.
"I think it's quite nice because I'm not just normal," he said. "I'm individual."
Practical advice for dyslexics
"I kind of want to be a policeman because I want to try to help people, and just because I'm dyslexic doesn't mean I can't do it.
"You can do anything if you want to do it."
And there are several celebrities who are said to have dyslexia who prove Cameron's point, including Jamie Oliver, Robbie Williams and even the man behind Mickey Mouse, Walt Disney.
