(3) K-3 Photographs by Chad Phillips. Rhyming sentences describing equations ("10 monsters looking fine! / 1 folds down. / Still up?...") help put subtraction in context for young learners. Photographs of monster finger puppets, pipe-cleaner dogs, and other trinkets illustrate each problem. A letter at book's end connects the content with Common Core State Standards and gives parents and teachers ideas for other activities.

(3) PS Photographs by Chad Phillips. Number-themed rhymes encourage readers to fill in the blanks ("Not one thing. / This box is clear-o. / How many inside? / I count..."); while many counting books stop at ten, this one usefully goes to twenty. Accompanying well-composed photographs consist of animal figurines and various tchotchkes. A letter to parents and teachers is appended.
