Monsters are used as an example to illustrate that multiplication of the natural numbers is associative. (JT)

This is the third in a series of articles on using mathematical techniques from history to provide an interesting way for middle graders to practice math. (Editor)

Assessment of effects of school principal involvement on acquisition of multiplication facts by 309 intermediate grade students found that taking the timed test three times per week resulted in consistent sustained gains and that a math game with the principal contingent on improved class performance was the most effective principal-initiated…

Early calculating methods and devices are discussed. These include finger products, the abacus, ancient multiplication algorithms, Napier's bones, and monograms. (MP)

Provides an alternative to traditional instruction in multiplication and division to develop computational fluency in students. (Author/NB)

Introduces addition, subtraction, multiplication, and division of fractions using area models such as rectangles and circles, or linear models such as the number line and fraction strips. (ASK)

Most people struggle to process information auditorily but this is often the way that it is taught. Presents a highly effective method for teaching multiplication that can be accessed at students' fingertips. (ASK)

Presents an activity on visualizing fingers for arithmetic, counting, and multiplication. (ASK)

Presents problem situations that support students when discovering the multiplication principle, permutations, combinations, Pascal's triangle, and relationships among those objects in a concrete context. (ASK)

In this article, the author describes her attempt to develop more interactive mental mathematics sessions. She observed that her students perceive the multiplication tables as a series of facts which are either known or not known, not as tools which could be used to derive other facts in a flexible manner. She therefore undertook the task of…

It is not often that one can introduce primary school students to a problem at the forefront of mathematics research, and have any expectation of understanding; but with magic squares, one can do exactly that. Magic squares are an ideal tool for the effective illustration of many mathematical concepts. This paper assumes little prior knowledge on…

In this article, the author presents an innovative approach to teaching multiplication facts for children in middle school or younger. After introducing the dangers of some contradictions that persist, relating a brief summary of related research and guidelines regarding math facts and their relation to strategic approaches to more complex math,…
