Summary:  “10 ants weigh the same as 1 ladybug.  9 ladybugs weigh the same as 1 grasshopper.”  And so this book goes, counting down from 10 to 1, with each page showing a progressively larger animal that weighs the same as that number of the animal from the preceding page.  The final, largest animal is a swan, which weighs the same as 362,880 ladybugs.  The last page shows all the animals with each one’s weight shown in ounces or pounds.  32 pages; ages 3-6.

Pros:  A fun introduction to weight and relative sizes for the youngest readers.  The simple, cute animal illustrations will make this an easy sell.

Cons:  You’ll need to look elsewhere for an introduction to units of measure and other information about weight.
