How about preparing a Powerpoint presentation of loads of images of toys / pastimes - they could also ask their parents / grandparents what their favourite toys as children were- hula hoops or Barbie dolls, whip and top or yo-yo, if you've got images can be much more evocative.
You could do a "fashion parade" in the same way - organise images into a power point pres. Or even draw out "paper dolls" with a colouring in sheet of dresses to colour, cut out ( don't forget the tabs) and dress as at start of 60s , middle and end. Remember, at start we all wanted to look like the adults, then came minis, etc - and at the end, Maxis - !
