Kids love a treasure hunt. Gather together some toys, Hot Wheels cars or mini figurines, wrap them in foil balls and hide them around the house or garden. If you have alphabet figures, you could wrap these and have your little ones put them in order. Throw in a box of raisons or other treats too just to make it fun. If you have 2 younger kids, this is also a great way to get them to practice taking turns. One child goes looking, returns back, unwraps then its the next players turn!
