Young students learn to comprehend the many uses of numbers as they engage in number games and fun-to-solve puzzles. Starting with counting, they advance to arithmetic, fractions, decimals, and the different ways of measuring. Teachers in grades 3 and 4 will appreciate the new Painless Junior Series of classroom helpers. Designed to resemble titles in Barron's Painless Series — which are used in middle school and high school classrooms — the Painless Junior books feature larger page sizes, amusing illustrations, games, puzzles, and an approach to their subjects that reflects third- and fourth-grade curricula. Their purpose is to inject an element of enjoyment into subjects that many younger students find either boring or mystifying. Kids' understanding will improve as they have fun learning.
