(2nd grade - 4th grade) 2 x 2 = Boo is a cute Halloween-themed multiplication concept book that works any time of the year. In short chapters that each focuses on one number (from 0-5), vampires, witches, skeletons and other creepy crawlies pose and answer ghoulish questions that not only teach multiplication facts but also visually illustrate the equation being covered.
We agree with School Library Journal who praised the book for teaching multiplication, calling it "an entertaining alternative to rote memorization; it's a little silly, but it works."
Note: The comic-book format
makes teaching with it tricky. Unless you have a document camera to project on a
screen, this book is better suited to small groups
or individual reading. Below are spreads from
inside 2x2=Boo!, to give you an idea of what the illustrations look
like, and how math is integrated. This first spread is from Chapter 2: Seeing
Double, in which a young witch finds glasses with the following
directions: "Dr. Spook's Doublevision Spectacles. Directions: Put on
glasses and stare at something. Multiply by two---the item will double."
