Do I need extra parts if 3 children will be using the kit?
That depends on your children and the kits you choose. We give further recommendations on the Extra Parts page for each topic (see links at left).

What should I do for 4 children?
We recommend getting 2 kits to share. Order from "Select your Own Topics" (below). Make your first and second choice be the topic you want. It will be like ordering 2 kits, but saving $10 on the second one. And they will probably come in one box.
NEW! Create your own 2-in-1 or 3-in-1 kit and save!
Save $10 for each topic beyond the first (saving included in the prices shown)
Or use this to buy 2 or 3 of any one topic, saving $10 on each beyond the first.
Choose First Topic . . . then Second Topic . . . and Third Topic (optional)
