Here is a great book for kids who know how to read, and now need to learn how to read in order to LEARN.
The pictures are fun, and the concepts are clearly expressed.
I use this book with my own children once they are reading on their own. This solves typical study problems, such as retaining the information, knowing how to USE the information once studied (application), comprehending what is read.
This is actually a brilliant technology - easy to learn, easy to apply, with excellent results.
