I just LOVE the activity packs that Usborne produces. Each pack contains 4 activity books and come in a handy carry case. This month, new additions include the Step by Step activity pack. Teachers love them. Kids love them and for only $15.95 before shipping/tax these gems are a steal. Each book retails in it's orginal size for anywhere from $8.98- $12.95. These a a MUST for any household!!
