Shape And Pattern (Math Magic) - Hardcover

David Clemson teaches primary mathematics education at the university level. Wendy Clemson is an experience primary school teacher and educational consultant. Together they have written a number of innovative books and articles offering stimulating mathematics activities to children.

Grade 2-5-Two uneven offerings. The first title covers addition and subtraction of one- to three-digit numbers, basic facts, counting by twos to fives, odd and even numbers, and estimation. Thirteen chapters present games, puzzles, and craft activities to reinforce these concepts and operations. While the suggestions are hands-on and amusing, most of them stress drill and calculation rather than creative problem solving. Also, there is no mention of regrouping, though children are expected to perform calculations in which it is required. One problem, which focuses on choosing a "likely" answer, is simply inaccurate. The question, "How much does a five-year old weigh?" has three possible answers: "less than 1 ounce," "less than 1 pound," or "7 pounds." One would hope none of the above. The second book introduces two- and three-dimensional shapes, symmetry, right angles, square numbers, mapping with a grid, and compass points. Again, 13 activities reinforce these concepts. In both titles, each topic is covered in a spread that includes a list of materials needed, step-by-step instructions, and, often, a challenge problem to solve. The presentations are colorful and busy with cartoon graphics and occasional color photos. Still, the characters are flat and corny; the illustrations, functional rather than artful. Teachers, rather than children, are more likely to use these books, though students, with adult help, could utilize some of the ideas for math-fair projects.
