A child uses a familiar standard to measure and compare the growth of a seed. It is spring, and a child is in the garden planting a sunflower seed. Eventually, after adding dirt, water, sun, and time, the seed sprouts. Bit by bit the seed reaches toe height, then knees, waist, and shoulders. By summer, the plant is taller than the child and produces a giant sunflower. The backmatter explains that these types of experiences will help children understand measuring tools later on. A "Try This!" section offers a few suggestions to encourage further activities to help children grasp the concepts of size and measurement. Other books in the series are Circle! Sphere! (readers learn about shapes as a group of children blow bubbles); The Last Marshmallow (division and fractions are simply presented when two children with a cup of hot cocoa each must figure out how to share three marshmallows); and What Will Fit? (spatial sense is explored as a child at the farmers market decides what will fit best in the basket). All books have a brief explanation of the math concept presented and a concluding section with suggestions for further related activities. Multiaward-winning Lin presents the concepts in easy-to-understand short sentences paired with simple and attractive illustrations. The children depicted are Black and Asian. Adults looking to engage little ones in early math concepts will not be disappointed. (Board book. 1-3)

In board book form, Lin accomplishes that most difficult of tasks: creating engaging, accessible, age-level-appropriate, not-too-fussily illustrated stories that also teach something. In this case it's math. Each entry homes in on a specific mathematical concept, while together providing a tour through the seasons -- and a slice-of-life portrait of three friends, Olivia, Mei, and Manny. In the springtime-set Knees, Mei observes measurement and comparison as she cultivates a sunflower. Circle! Sphere! proves the mind-stretching fact that the children's three different-shaped bubble wands produce the same-shaped bubble. Fit's setting is a fall farmers' market and illustrates Olivia's spatial sense (and taste in produce). Wintry Marshmallow touches on division, both mathematical (how to split three marshmallows between two girls...) and behavioral (...without ruining the friendship). The illustrations are signature Lin -- think The Ugly Vegetables (rev. 9/99) and the Ling and Ting books -- with bold, saturated hues; thick black outlines; judicious use of frames; eye-pleasingly tidy details; and nothing extraneous. Brief "Exploring the Math" notes and "Try This!" suggestions, addressed to adults and written by an early math expert, are appended. All together, these diminutive math storybooks add up to a whole lot of fun.
