  • "Brilliant site. I'm on it all the time. Really helps, I can say that much! No idea how you could make it better apart from making it bigger, so lots of schools know about it."

  • "I love the starters but do not have time to work out the answers - sometimes I don't have the brain power either! I have found the answers to most of the problems when scrolling down but sometimes they are not there.......a disappointment for me as it means the activity cannot be used if I cannot work it out myself in the meagre time I have available to plan.
    Great work though, and free, thanks very much."

    The answers to all of the problems would make it easier to use.
    The answer to this one is 12 if that helps anyone. ."
