## Editorial Reviews

Publishers Weekly
In this counting book about doubling numbers, monkeys Jill (in pink overalls) and Jake (in stripes) find all sorts of applications for math on the playground: "With just their knees,/ they grip the bars./ They're upside-downside/ circus stars. 2 knees + 2 knees = 4 knees." Along with their animal classmates, they take part in games like four square and jump rope ("Their jumping makes/ a rhythmic sound,/ while friends turn ropes/ that slap the ground. 3 kids + 3 kids = 6 kids"). Franco's rhymes swing effortlessly along with the animals' play, giving the simple addition lesson read-aloud appeal. Ages 4–8. (July)
From the Publisher
Review, School Library Journal, June 1, 2011
"Young students will enjoy the book for its play aspect, not realizing that the math lesson is built into it. Every elementary school needs this one."

Review, Booklist, July 1, 2011
"The bright, buoyant line-and-watercolor illustrations amplify the cheerful tone of the story while clearly delineating the objects meant to be counted. Useful for teachers and fun for students."

Children's Literature - Candace Deisley
Here is a first look at addition: adding the same number twice. The reader is presented with two children lining up for recess in pairs. One friend plus one friend equals two friends. The following pages offer rhymes and examples of the little monkeys and their other zoo animal friends playing on playground equipment. We are shown four knees, then six kids, until we finally reach ten overhead climbing bars plus ten bars equaling twenty bars. Then the bell rings signaling it is time to line up to return to class, and the monkeys, Jill and Jake, line up together and they are one plus one "just like before." Amusing and pleasing watercolors invite the reader to read and reread this great book. The pages are clear and simple, and include enough other animals to help a child look for other activities on each page. The characters are dressed in typical school clothes, with the lack of shoes necessary for the monkeys to use their feet! Reviewer: Candace Deisley
Kirkus Reviews

This jaunty rhyme set in a school playground serves as a playful introduction to the mathematical concept of doubling.

Jill and Jake, monkey friends, join their other animal classmates at recess to gallop, race, climb, jump rope, kick ball and blow bubbles, while coupling their playtime antics with matching addition equations. When they hang from the monkey bars "with just their knees, / they grip the bars. / They're upside-downside / circus stars," proving "2 knees + 2 knees = 4 knees." Children accustomed to the play-to-learn environment of today's curriculum will cheerily join in the fun with this precursor to multiplication that extends the math lesson to the pleasures of physical activity. Full-bleed double-page watercolor spreads offer a variety of playground scenes, each with a different equation to encompass the doubling sums of the numerals 1-10. Children will easily grasp the concept of mathematical equations as they readily count items clearly depicted in each scene and offered on the endpapers.

The frolicsome verse and efficacious design combine to highlight a precise exercise, making this concept picture book a twofold success.(Picture book. 6-8)

School Library Journal
K-Gr 2—A classroom full of animal students is released for recess. Jill and Jake, two monkeys, lead the line to the playground. "1 friend + 1 friend = 2 friends." Thus begins the exercise of doubling all the numbers from one to 10. Readers can follow the antics of all the characters on the playground and count the objects mentioned. Each spread has a math equation as well as a rhymed verse. When the bell rings, play ends and the two monkeys lead the line back inside. The large watercolor illustrations show a joyous romp through recess as the creatures blow bubbles, draw pictures, eat a snack, and generally have a good time. Young students will enjoy the book for its play aspect, not realizing that the math lesson is built into it. Every elementary school needs this one.—Ieva Bates, Ann Arbor District Library, MI
