Sometimes resources come from out of the blue.
My girlfriend is a teacher and is also participating in "an even start" National Tuition Program. So she was looking for resources for numeracy and literacy and came across this awesome site.
Holy Cow! It's the motherload of interactive websites and most can be used with an eBeam. Some of these sites are in my list but a fair few are not - one of the great things though is that it is organised by teaching concept. Much easier to find exactly what you are looking for.
