The comprehension questions are designed to be compatible with the National Geographic Kids series titled Frogs! by Elizabeth Carney. This particular book is Level 1. The Accelerated Reader program rates it as a 2.6 reading level. Questions include short answer, true/false, multiple choice, and vocabulary. An answer key is included. Extend the lesson by adding a lap book or layered-flip book for an animal research report. These items can be found in my store at www.teacherspayteachers.com/Store/Kathryn-Larson-8756.
