This book is good for organizing information occurring in 4. You can make the tabs all the same size, or you can customize the flaps to fit the information. Just simply fold the paper hot dog style and cut the top flap into as many tabs as you need. 

This book is also good for showing a short sequence. Ex: Life cycles. 

Students can also use this to collect data for an experiment that may last several days. One one flap they draw what they see, on the flap underneath, write their observations.
