Sponge Bunnies or Balls, Cut and Restored Rope, Vanish a silk with a TT, Stratosphere, D'Lite's if you have the proper lighting, A Change Bag Routine, Cups and Balls, Magic Coloring Book, Hippity Hop Rabbits, Linking Rings, Pen through Dollar, Tea Kettle Trick, Break a way wand, Peanut Butter and Jelly trick, Vanishing deck of cards (this is the one that is about 5 bucks in almost any brick and mortar shop). Something with a jumbo coin perhaps. Torn and restored newspaper.
These are just ideas and some of the effects that I use. By no means do I want you to go purchase a whole new set of props but if you don't have anything at all like these...hmmm...you may want to reconsider the gig. 7 year old kids do not want to watch card tricks, and color changes for a half hour.
You basically want very visual effects with things appearing or disappearing. Card tricks for kids that age are probably not going to be much fun. I wouldn't do more than one card effect. Attention spans are very quick at that age. Your show shouldn't go over 25-30 minutes for this particular age group. Have helpers and get the kids involved. You need to laugh a lot and show them you can have fun but also you must be in complete control as well.
Let me know if you have specific questions. Reality One is a specialist in this particular type of gig as well.
