Get the kids you work with to teach you some! I did my special study at college some 25 years ago on them and every so often I ask the children to update it. You may find they are still playing ones you did and have forgotten.
Their parents/grandparents are also a good source.
One book I use a lot is This little Puffin published by Penguin ..... just a minute wasn't there similar thread on this not long back?
