This week I'm featuring "Biggest, Strongest, Fastest" by Steve Jenkins. These are the kind of facts that many of our students just adore being able to share with people less in the know :)
This book details the "world records" of the animal kingdom. It is filled with math -- comparisons, scale and proportions -- and could be extended with activities. Just to suggest one -- use some long pieces of paper and model the exact length of some of the animals to give students a concrete idea of the size.
