With school just getting back into the swing of things, I've been on a bit of a non-fiction run lately. But there's so many wonderful books out there, for different young audiences, to inform and entertain that there is no shortage of new books to review. I'm Longer Than You is a different kind of math picture book in that it focuses on measurement and comparisons for the early reader kids at school i.e., Kindergarten to Grade 3.

In Carolyn Fisher's new picture book—she has previously illustrated a number of books for others like Summer Feet and Weeds Find a Way, as well as written and illustrated her own including Cells: An Owner's Handbook—a Supersaurus dinosaur and a blue whale argue about which animal is the longest. What's the easiest way to determine who's right? An inchworm suggests measuring them. So, the little worm gets to work.

But after 12 hours of measuring the blue whale–it's 1300 inches long—it's time for it to pupate and leaves the two competitors at a loss. In comes the centipede who measures exactly one centimeter. Now the Supersaurus and the blue whale, salivating for the lunch the winner would get, wait for the centipede to do its work. Twelve hours later, the Supersaurus is also measured but in centimeters. With a little math and conversion between units, the contest is resolved.

What a fun way to introduce measurement, systems of measurement, comparison and conversion between units! Carolyn Fisher has found a way to tell a story—and a funny one at that with the contest between two humongous animals—and introduce several math concepts that might be hard to grasp easily. Measuring is a complex concept, and she takes it from its most basic, i.e., how to measure, through the different ways people measure things and what units to use and then to conversion. As such, I'm Longer Than You! can be used for our youngest readers just being introduced to units of measurement to middle graders who are learning conversion.

As a non-fiction book, I'm Longer Than You! is anything but dry. It's educational but quirky in its delivery of information. With her illustrations which are hand-drawn on a tablet, Carolyn Fisher makes this a true picture book, albeit an information book embedded in a story. Her art is colourful and bold, and the organization of information, whether it's the true rendering of the inchworm and centipede's sizes or the decision tree to pick appropriate units based on size—after all, using an inchworm or a centipede for these enormous animals was unwieldy—is accessible and presented with clarity and playfulness.

 

I know primary teachers will love using this book to introduce the concept of measurement, but it will be an entertaining starter for any lessons on measurement. Kids will love the contest and comparing animals—this could be a great scaffolding story for lessons on the diversity of living things—but they'll get a fabulous introduction to measurement and some related math concepts like conversion between metric and imperial units. It's a win-win for the Supersaurus, the blue whale, and the kids who get to read or hear the story in I'm Longer Than You!
