UP TO MY KNEES!

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.
