Less Than Zero (MathStart 3)

“Kids, young and old, fall in love with math when they see how real-life and effortless it becomes thanks to these books.” —Kimberly D. Mueller, Ed.D., First Grade Teacher, Ashbrook School, Lumberton NJ

Less Than Zero is perfect for teaching negative numbers to second, third, and fourth graders. Perry the Penguin needs 9 clams to buy an ice scooter—but he's not very good at saving. As Perry earns, spends, finds, loses, and borrows clams, a simple line graph demonstrates the concept of negative numbers.

Kids will love the story and the illustrations by Frank Remkiewicz. Parents and educators will love how the story and pictures make understanding the math concepts a breeze—as well as the concrete examples of how math works. The book contains activities for adults to do with kids to extend math into their own lives.

In His Own Words...

"I was the kind of kid who was always reading or drawing. Since I was drawing well before I started school, I always considered art to have seniority over the likes of long division and medieval history. This attitude got me into difficulties more than once. My favorite subjects were horses, cartoons, wildlife, and contraptions that rolled, floated, tooted, or flew. My heroes of the day were illustrators like Bill Peet, Robert Lawson, and Kurt Weiss. They provided me with a screenful of imagery that I'll never forget.

"Winter in kindergarten found us all painting Santas at our tables. Mine came out so good that I was asked to do it over again on a huge piece of brown paper that covered the chalkboard. Santa would be bigger than me. I was excused from the regular stuff, given larger brushes, more paint-and sure enough, here came Santa. This was only the beginning. Other teachers, seeing the mural-sized figure, 'borrowed' me to do the same for first- and second-grade classrooms. Flattered but somewhat embarrassed, I took heart, since these gigs were getting me out of a lot of tedious activities like nap time, scissors, yarn, and flash cards. 'All I ever needed to know, I learned in kindergarten' may be true. Twenty years later I found myself on Madison Avenue at Norcross Greeting Cards-yes, drawing Santa Claus.

"I've always been drawn to the field of humor. Since I'm writing and illustrating my own stories now, I try to make them funny in an outrageous or off-the-wall way. During classroom presentations, I again find myself by the chalkboard in front of the kids. Now we are seeking ways to write and draw those ideas that squeeze their way through the everyday chores of our minds. It's a thrill to watch my own book being read by a group of children, and I like it when they smile. But I love it when they laugh."
