Just released yesterday and FREE  – Spatter and Spark, a cute interactive book from Polk Street Press. Spatter (an artistic porcupine) and Spark (an inventive fox) team up to figure out how to get a look at Hubert, the baby crow, so that Spatter can paint Hubert’s picture. Kids are invited to help as Spatter & Spark problem solve their way through the story. There are 10 interactive scenes within the app. Each scene is beautifully illustrated by Luciana Navarro Powell, the illustrator of Goodnight Safari (another wonderful FREE app from the same developer  – see my August 28th review). The story, primarily for 4 – 6 year olds, is very cute with purposeful interactivity that adds to the story. Spatter and Spark could also be used with older students to encourage them to think and write about their own inventions. An activity pack (with 4 additional activities) is available as an in-app purchase. Very nicely done – recommended!!
