Thank... er... Goodness!

As tobybarrett has said, some schools and individual teachers have already been doing this. Even with very young children it is possible to explain that the Earth is very very old and that human beings are only late arrivals. All children are fascinated by dinosaurs and there are plenty of opportunities when talking about them to explain that there were no humans around at the time and that a lot happened in between.
There are plenty of well educated teachers who have been quietly doing their bit in this way.
Now, it will be possible to ensure that all children have the same opportunities to learn.

How is that insane Christian 'Academy' up north going to deal with this, I wonder? How do Adam and Eve and Noah's Ark fit in with what they're supposed to teach?
