Students love this hide and seek game! Print the egg sheets double sided so that the challenge appears on the back of each square. Chop the activity sheets and put them in plastic eggs. You can buy them online cheap. Hide the eggs around your classroom and let the students find them according to the powerpoint. For the Golden Chicken challenge I put a little furry chicken in the egg but you could just put the activity in there.
Of course you can always simply use the egg sheets as grammar task cards too!
