This witty history of math starts with ancient number systems and wends its way through notable developments and entertaining asides ("The Italian city of Florence...banned zero...in 1299. Other places feared algebra and thought of zero as black magic") to the present. Lighthearted "Schoolhouse Rock"–style cartoons show historical smart alecks cracking wise in dialogue bubbles, and the inclusive text celebrates Muslim, Chinese, Mayan, and Indian contributions. While some topics will probably be beyond the capabilities of the target audience, math geeks will go reciprocal over this appealing window into mathematical thought. Back matter includes a timeline, famous math mistakes, math puzzles (with answers), a glossary, and an index.

"An eight is two circles, / One high and one low-- / Like the jolly fat fellow / You build out of snow." Rhyming quatrains describe the shape of each number and relate it to images in the mixed-media illustrations, whose casually diverse cast of dynamically exaggerated adult and child figures picnic, bike, whale watch, and go trick-or-treating in a vibrant retro palette. Subtle dotted lines tracing the number shapes are repeated in the "How many numbers can you spy?" seek-and-find at book's end. A final spread uses images from the illustrations as counters to show zero to nine in this preschool-appropriate number- and counting-palooza.

Large swaths of pastel colors and simple cartoons illustrate this exploration of the metric system. After pointing out that English measurement and metric measurement are two ways of expressing the same information, well composed spreads compare English and metric units in the areas of length, weight, and volume. Frequent examples relate to readers' experiences (a football weighs about a pound; seven apples approximate a kilogram) and emphasize the easy scalability of the metric system, while occasional activity suggestions encourage readers to get involved. Back matter includes unit conversion notecards and ways to "Think Metric!"

Talking Math series.
Danielson upends the traditional counting-book format by letting viewers decide for themselves what to count. Take, for example, a photograph of a pair of black lace-ups tucked into an open shoebox. Counting options include the shoebox, the shoes, the shoelaces. Then there are eyelets and aglets. The question "What other things can you count?" encourages viewers to keep looking closely. Danielson's open-ended approach will leave viewers lingering over the pages.

After introducing the special quadrilateral known as a square, Adler and Miller's latest collaboration veers off on a surprising and completely worthwhile tangent to explore, in depth, how a quadrilateral's angles always add up to 360 degrees. The usual suspects--rectangles, parallelograms, rhombuses, trapezoids, kites--are then defined. Engaging activities and easy-to-understand illustrations make this a solid follow-up to *Circles* and *Triangles*. Glos.

This lyrical introduction to patterns found in nature eschews formal definitions (the term *fractals*, for example, is never used). Instead, Barss's focus is on encouraging children to explore and ask their own questions about branching river systems, spinning planets, and spiraling seashells. Eye-catching patterns abound in Stewart's texture-rich illustrations, rendered with silkscreen printing and digital media. Reading list.

Annemarie (from Brunetti's *Wordplay*) and her classmates are assigned to draw twelve things in sets; she and the others brainstorm with their parents how best to complete the assignment. A simple easy-reader text (leveled for "brand-new readers") and brightly colored comic-panel illustrations will help young children grasp this introduction to patterns and basic multiplication. Appended with tips for reading comics with kids.

Master Math series.
Illustrated by
Jo Samways.
Clear and colorful, these introductory math books feature hands-on and picture-based activities using the Singapore math approach, in which children progress from concrete to pictorial to abstract understanding of concepts. The content is engaging and pedagogically progressive; many important activities (especially those requiring manipulatives) are described in "Parent and Teacher Guidance" sections, making the series best suited for classroom or homeschool use. Review covers these Master Math titles: *Get in Shape*, *Get to Know Numbers*, *Measure Up*, and *Super Calculations*.

McKellar keeps the tone light without sacrificing any content as she teaches--and demystifies--"new math" strategies for adding and subtracting with one-, two-, and three-digit numbers. She explains the concepts clearly and puts her own spin on everything from ten frames, number bonds, and part-part-whole boxes to regrouping, ungrouping, and mental math tips. Amusing cartoon illustrations feature McKellar bantering with mathphobic Mr. Mouse. Glos., ind.

In Adler and Miller's latest math-tastic collaboration, they discuss the concepts of estimating and rounding and the subtle-seeming difference between them. The book is a bit wordy, but readers will stick with the invitingly tidy illustrations showing smiley kids and dinos navigating situations in which estimating and/or rounding save the day--how else to determine how much pizza to order?

Adler and Miller return with another breezy math lesson, this one centered on assessing the value of U.S. coins and bills ("Counting money is money addition"). Cheerfully co-teaching the lesson are digitally rendered Washington, Lincoln, Jefferson, Kennedy, Franklin, and, in a wheelchair, FDR ("My portrait is on the dime"). The book includes addition and subtraction challenges, with answers at book's end.

To plan the "Blowout Bug Jamboree," an ant is used as the unit to measure other insects. A simple text makes size comparisons while charts visualize them; later, data is presented with a bar graph and a pie chart. A final gatefold shows all the insects on a "Jamboree Buggy-go-round!" A lively, approachable introduction to nonstandard measurement, comparison, and graphing.

Sir Cumference and Lady Di of Ameter use their burgeoning knowledge of fractions to thwart some thieves ripping off merchants at the Fracton Faire. As always, Neuschwander's medieval-set math lesson goes down easy, in part because readers are learning right along with the characters rather than having to sit through a lecture. Geehan's jewel-toned acrylics capture ye merry olde mischief.

Each two-page spread presents a hypothetical real-world math word problem, contextual background, and an answer using basic math and measurements. All the data to answer the fifty-three included questions is documented by appended sources, and a final chapter offers young readers some tricks for solving math puzzles in one's head. The book is artfully designed, with eye-catching color photographs and illustrations.

In this Swedish import, two dozen or so simple activities, organized seasonally, are designed to reinforce basic mathematical concepts (counting, shapes, etc.); unpretentious vignettes feature children happily engaged in the tasks at hand. Many of the activities are pedestrian ("How many snowballs can you make in 1 minute?"), but they will provoke thought and, equally valuably, get kids out of the house.

After differentiating a circle from its 3-D relatives (spheres, cylinders, cones), Adler provides step-by-step directions for drawing the 2-D shape and its various parts (diameter, radius, sectors, etc.) and for measuring its circumference and area. Clear visuals reinforce activity instructions, geometry terms, and concepts (e.g., *pi*). Friendly animal illustrations provide opportunities for identifying specific circle parts. Answers to the activities are appended. Glos.

Shapes Are Fun! series.
These books for very young beginning readers introduce different shapes, each one discussing a shape's properties and providing examples of the particular shape around us. Stock photos show the shape highlighted in different settings, from a circular pizza to hexagon-shaped tiles to triangular bridge supports. The presentation is formulaic; the simplistic texts are undemanding. A counting game concludes each volume. Glos., ind. Review covers these Shapes Are Fun! titles: *Circles*, *Hexagons*, *Ovals*, *Rectangles*, *Squares*, and *Triangles*.
