Four kids and their sidekick, Petey the Parrot, run a lemonade stand whose patrons include all kinds of wacky neighbors-even a juggler. They create a bar graph to track the rise and fall of their lemonade sales. Author Stuart Murphy and illustrator Tricia Tusa make understanding bar graphs a breeze with lively art and a warm story. This is a Level 3 MathStart book, which is perfect for kids ages 7 and up. The MathStart series uses funny stories and colorful art to show kids that they use math every day, even outside of the classroom! Each book features an activity guide to have fun with the math concepts presented in the story. Supports the Common Core State Standards.

Matthew has found a treasure map, and soon the Elm Street Kids' Club is off on a quest. The map guides them into a wonderful, magical world, but it's the real-life math skills of understanding distance, scale, direction, and symbols that will help Matthew, Sheri, Meg, Danny, and Jed -- with some assistance from Petey the parrot -- find a treasure hidden fifty years ago.
