I loved this game when I was young (not yet: P) This can work in pairs or individual children give a small piece of paper to start. Enter a keyword or mini drawing on paper for an example of a design that is expected to microwave with an arrow pointing inside. For an example of a word puzzle might say, "You used to heat my food and do not put metal in me." Once children idenifies the track and inside the microwave to look inside the microwave and what do they find? Another clue! That idea should lead to another and another and another until they reach the last track that leads them to their treasure!. Everyone children / couple could get 10 or 20 different tracks, more difficult tracks for older children and easier to track for kindergarten. Or an average diffuclty. You could have a bonus prize for the first person wide to find his treasure of all children playing or you can give the prizes Bonu per grade. Sure use the arrows in his drawing and made more clear and understandable. You can hide the tracks almost everywhere. Your examples are perfect. You can also try: Low or digital watches, in drawers under the bed in the kit Under the rug, under the mouse / pad within books on the shelves or in the refrigerator over the sky of the window is the limit! Hope I helped, and I get 10 points …
