Mathematics Teacher, 1983

Included in this section are brief articles outlining an approach to teaching mental computation, an inductive approach to algebra, and using football to teach probability. (MNS)

Descriptors: Algebra, Computation, Games, Induction

Peer reviewed

Smith, Susan M. – Mathematics Teacher, 1981

Activities geared to reinforcing the skills involved in solving linear equations are given. The material is prepared on worksheets designed for duplication. Student use of calculators is suggested, and the material can aid in promoting mental computation and estimation. (MP)

Olsen, James R. – Mathematics Teacher, 2015

After studying the Common Core State Standards for Mathematics (CCSSM) and brain-based learning research, James Olsen believes mental math instruction in secondary school mathematics (grades 7-12) and in teacher education programs needs increased attention. The purpose of this article is to share some keys for teaching mental math. Olsen also…

Moore, Nathan T.; Deming, John C. – Mathematics Teacher, 2010

The garlic problem presented in this article develops several themes related to dimensional analysis and also introduces students to a few basic statistical ideas. This garlic problem was used in a university preparatory chemistry class, designed for students with no chemistry background. However, this course is unique because one of the primary…

Hall, Lucien T., Jr. – Mathematics Teacher, 1984

The difference between estimation (the mental skill of making an educated guess) and approximation (finding a result precise enough for a specific purpose) is discussed. (MNS)

Descriptors: Calculators, Computation, Definitions, Mathematics Education

Peer reviewed

Mathematics Teacher, 1977

The topics discussed are, "Helping Students Understand the Distributive Property,""Converting from Base 10: Nonintegral Bases?,""Rapid Mental Squaring of Mixed Numbers," and "Some Nonstandard Binary Operations and their Properties." (JT)

Descriptors: Algebra, Computation, Fractions, Instruction

Peer reviewed

Morelli, Lynn – Mathematics Teacher, 1992

Presents activities to visually explore the algebraic concepts of variable, constant, the distributive property, and combining like terms. Presents four transparencies that use visual models to understand exercises in students perform the same mental calculations on a number of their choice and obtain the same result. (MDH)
