PreS-Gr 1—Using big, bright numbers and images interspersed with photos of children confidently smiling, the author lays out basic arithmetical operations, from 2+2=4 to measuring weights and distances. The author explains how to use groups and number lines to reach solutions, and appropriately approaches such thorny concepts as estimating (Count It!), using units of measure beyond Standard and Metric (Weigh It!), and adding up sets of coins and currency (What's it Worth?). Each volume includes both number and word problems, and ends with a hands-on activity. The frequent focus on practical applications gives this a leg up over more fanciful introductory series, such as Heinemann's "Animal Math." VERDICT Lively support for primary level arithmetic instruction.
