Schools in England are being told to "actively promote British values" by the government's education secretary Michael Gove.
He said values like democracy, respect and tolerance of those with different faiths should be taught in schools.
The announcement was made on Monday, following claims that hardline Muslims were trying to impose their views on a group of schools in Birmingham.
Leaders of one of the schools, Park View, said the claims weren't true.
The UK's Prime Minister David Cameron said he backed the plan to teach "British values" in schools.
He said "freedom, tolerance, respect for the rule of law" were the types of things he hoped would be taught in schools.
