Zachary, our main character always seems to forget to bring in an object for the weekly math show-and-tell. Zach has to think quickly outside the box shows different geometric concepts. It doesn't help that he's always competing with Tyler, the class show-off, so he has to be creative with whatever he can get his hands on. It's a fun book that helps show that math can be found in everyday objects. Not only that, but the book helps break down math concepts like measurement and area for kids. For the grades I recommend. I would put down 3rd to 5th grade. ( )
