Review by Booklist Review
Each of these new books in the Math World series walks readers through a basic math concept via a fictional story that makes the process feel less like work. Explanations are built into the dialogue, and the characters and scenarios in the stories, set either at home or in a school classroom, are realistic and relatable. In Telling Time, an older sister helps James (or Ninja, as he prefers to be called) count the minutes until a friend arrives to play. The stories typically end on an upbeat note, with a silly joke or clever ending. Longhi's illustrations, focusing on ethnically diverse characters, add great charm to the series. However, the large amount of dialogue and the number of characters in each book distract somewhat from the math concepts themselves. The presentation of these concepts is perhaps not clear enough for a first introduction, although these appealing books are still great for review.--Aronin, Miriam Copyright 2015 Booklist
