Kids Love Math Crafts [PDF ebook] 

Math is the only language shared by all human beings across the globe. Students will practice their math skills, including addition, subtraction, and fractions, as they cut, fold, measure, and draw. They will create a piggy bank to keep track of their money, learn Roman numerals to send a secret message, and see how different shapes can fit together to make a stegosaurus shadow puppet. In addition to the ten projects, patterns that are easy to reproduce using a copier or printer are provided as well as a Learn More section with current books and websites.
