An alternate method for factoring quadratic equations is presented as being quicker and easier to use than the trial-and-error method. (MP)

An algorithm for long division is presented that involves only addition and subtraction. (MP)

Describes a calculator exercise that can help students develop a better visual and numeric feel for Newton's method. (KHR)

Computational algorithms appearing in early American arithmetic text are discussed. (SD)

The following ideas are shared: (1) a low-stress subtraction algorithm that eliminates the traditional borrowing process, and (2) an approach to graphing circular functions that looks at the process of modifying simple functions as a series of shifting, sliding, and stretching adjustments, with its biggest advantage viewed as its generality. (MP)

An approach to solving equations is presented. (SD)

The first section promotes use of student notebooks in mathematics instruction as incentives for pupils to do daily work. Part two looks at a geometric interpretation of the Euclidean algorithm. The final section examines an open box problem that is thought to appear in virtually every elementary calculus book. (MP)

An unusual algorithm for approximating square roots is presented and investigated using techniques common in algebra. The material is presented as a tool to interest high school students in the logic behind mathematics. (MP)

Factoring puzzles can be used to review computational technique and build readiness for factoring trinomials. (SD)

Topics covered include alternate methods for finding LCM and GCF, imaginative word problems, and a primes-breakdown method of factoring quadratics. (MP)

An algorithm is given for the addition and subtraction of fractions based on dividing the sum of diagonal numerator and denominator products by the product of the denominators. As an explanation of the teaching method, activities used in teaching are demonstrated. (MN)

Shows how to model Newton's method for approximating roots on a spreadsheet. (MKR)
