They interact with a free ipad app. So you buy the letters and get the app as a bonus. They also have them as numbers now too!
I had several gift cards from students and finally ordered some off of Amazon earlier this week. They came in the mail yesterday and I opened them right then!
Check these out:
The app took maybe a minute to download and I started playing with it. My 6 year old came over and wanted to know what I was doing... so I let her try it out too!
She loved it! She definitely would have kept playing except that ipad battery died. I haven't charged it this summer and it was on 5% when I started. Oops! I can't wait to use these this year. I even have a Donor's Choose page set up to hopefully get some more!
For now, they'll hang out in the cute pouch that comes with them!
