I found Mathemagic listed in the Cuisenaire-Dale Seymour Publications Middle School Catalog (800)-237-0338. The write up on the book is: "Fourty-four classic lessons on math topics that seem to have mysterious solutions. Students find the "secrets" to the solutions of problems and activities that explore logic and lateral thinking, number patterns, and more." It is 48 pages and costs $10.50 (#YA01724) This might be what was suggested. With your other problem: have you ever considered multiplying by using a matrix. In this case a 2 x 2 set of boxes. On the top row you would put one number broken down in hundreds, tens and units. On the side column you would put the other. Consider: 451 x 36 400 + 50 + 1 30 * * * 6 * * * You would find the product of each of the numbers to get the *. Then add up all of the stars. This method is used frequently in algebra when kids first start multiplying polynomials. -Marielouise, for the Teacher2Teacher service
