Transparent Bee-Bots mats are great. Firstly, they are cheap, approximately $40 AU and secondly, you can do so many things with them. If you are not familiar with Bee-Bots, read this blog post link before reading further.
Sarah, one of the Year 1 teachers from my school, was using a beautiful picture book called Hello Ruby (previous blog LINK) as part of her program. She created some Hello Ruby cards, slipped them inside the transparent Bee-Bot mats and then set students challenges.
You can do this with any picture book you are using with students. You simply create picture cards, insert them into the mats and then ask students to program their Bee-Bots to complete challenges or retell the sequence of a story.
