Everything You Need to Know about Math Homework: 4th to 6th Grades (Everything You Need to Know about (Scholastic Paperback)) Book

Who invented numbers? What are prime numbers? How do you do long division? How do you calculate percentages? If your child is asking for help with these questions, and you're feeling a little rusty, this is the perfect book to have on hand--for yourself and your inquisitive fourth- to sixth-grader. Colorful and accessible, this clear guide defines math terms and concepts with both visual and written description. For example, authors Anne Zeman and Kate Kelly describe a fraction as "one or more parts of a whole or a set," and they also offer the image of a necklace of beads to show how each bead is part of a set. The book is divided into the following sections: "Numbers and Number Systems" (ancient number systems, the decimal system); "Basic Math Functions" (math symbols, addition and subtraction, multiplication and division, fractions, rounding and estimation, averages and medians, properties and orders, story problems); "Measurement" (measuring length, distance, weight, perimeter and area, volume, temperature, time); "Geometry" (geometric shapes, symmetry, congruence, similarity); "Money and Monetary Systems" (U.S. currency, other currency systems); "Graphs" (plotting information, four kinds of graphs); "Statistics and Probability"; "Computers and Calculators" (the abacus, simple calculators, the computer); and a complete index. Information for the Scholastic Homework Reference Series was gathered from current textbooks, national curricula, and the assistance of the UFT Dial-A-Teacher staff. (Ages 9 and older)Read More
