Hello, Here are a couple of ideas for PK in the lab -- first of all, while 30 minutes seems like a short time, be sure to gather them as you start and finish to clarify what they have learned/done and how it fits with their "regular" class -- this tying the two classes together makes a huge difference in transfer of learning... There are many things you can do with PK in the computer lab... a lot depends on your students and their experience and the lab of course! For software I think you may want to look at Clickity Kids, KidPix, Max's Sandbox, A to Zap.... Of course there are tons of websites on my website for this age group (www.gaillovely.com) Gail
