Balance Math Teaches Algebra!
Algebra can be a very difficult course for many students who don't think abstractly. This book offers step-by-step, visual exercises using a balance scale to help with the understanding of 'balancing equations.' Similar to the format of the rest of the Balance Math series, this book additionally offers explanations and instruction for each step of the equation process. For example, the first page shows a balance scale that is level, having a 20 on the left pan and a square containing an x on the right pan. This would indicate that the two are equal. The next illustration shows a balance scale with the square containing the x on the left pan and a question mark (?) on the right pan. To the right of the illustrations is a box with these words, "From the 1st scale we know: 20 = x. Reversing the sides of an equation does not change its value. Therefore, x = 20 =?" Along with the verbiage is a fill-in box where the student will answer "? = ____." The problems are presented as puzzles that engage and really make a student think, and progress from simple to complex. Some review-type pages are placed intermittently throughout the book just to make sure your student understands and can apply concepts. The back of the book offers tips for working with the balance scale visuals, and answers with explanations. The method used for teaching the steps of equations and solving them reminds me a little of the Hands-On Equations products. This would be a super introduction to algebra for younger children, a great tutorial for someone having difficulty with equations, or helpful practice for anyone wants to keep their skills sharp. - Donna
We've come to expect great books from Critical Thinking Press. This series, written by an experienced algebra teacher, helps students to develop the ability to solve those tough algebra word problems using process skills. These excellent resource books include hints and detailed solutions should you get stuck. Algebra 1 covers breaking a problem into easily handled parts, translating words into algebraic symbols, ages and coins, mixtures, formulas, rectangles, d=rt, percents, and work rates. Algebra 2 contains breaking a problem into easily handled parts, solving a system of two equations with two variables, solving a system of three equations with three variables, general quadratic equations, indeterminate equations, false proofs, magic squares, and "choose a number". ~ Stephanie
