A modern adaptation of the historic lattice algorithm which can be used for multiplication and division is discussed. How it works is clearly illustrated. (MNS)

Four worksheets and teaching suggestions are presented, with the focus on mental computation for levels 2-3; factors, levels 3-4; and nonroutine problems, levels 5-6 and 7-8. (MNS)

Describes a microcomputer-based system for diagnosing children's multiplication errors which incorporates the knowledge base of all known systematic multiplication errors, and utilizes a modular approach to cope with the program's complexity. Each module's function, how the programs interact, and the design of pupil-machine interaction are…

This book reports on young students' strategies, the ways they construct knowledge, and how to support such development over time. Focus is placed on how to develop an understanding of multiplication and division in grades 3-5. The book describes and illustrates what it means to do and learn mathematics, provides strategies to help teachers turn…

Four ideas are presented, each a variation of the tic-tac-toe game. Recognizing three addends is the goal of the primary level game; experiences with basic facts and fractions are objectives for upper levels. Each worksheet includes objectives, directions, and comments. (LS)

The purpose of the research described in this paper was to develop and validate computer-controlled feedback procedures to help children learn to multiply two- and three-digit numbers. (Author)

The author criticizes an experiment of Moody, Abell and Bausell (EJ 038 323) on the grounds of inappropriate instruction and invalid tests. (MM)

An example of a lesson involving calculators that focused on calculator use is given. An examination of the traditional algorithm by the students led to student-directed investigations. (MP)

Certain properties of lenses provide a physical model of the mathematical concepts of multiplication of integral numbers and of similarity transformations in geometry. Further, they can provide a realistic concrete representation for rules governing multiplication of signed numbers. Suggestions for problems and classroom demonstrations involving…

The use of graph paper to outline arrays of multidigit multiplication problems is promoted. (MP)

An unusual way of using the long multiplication algorithm to solve problems is presented. It is conceptually harder, since it involves negative numbers but is easier to perform once mastered, since the size of the multiplication table required is smaller than the standard one. (MP)

An analysis is presented of pupil responses to several items on the second National Assessment of Educational Progress (NAEP) mathematics survey which focused on the concepts and models of the fundamental operations. (MP) Aspect of National Assessment (NAEP) dealt with in this document: Results (Interpretation).

This discussion concerns itself with difficulties encountered by students in multiplication and concludes that when children understand a problem they can usually solve it. (MP)

A Copy/Cover/Compare method of teaching multiplication facts to a sixth grade student with learning disabilities was evaluated. Results indicated that the Copy/Cover/Compare method was effective in increasing percent correct for the targeted multiplication facts. Practical implications of employing this drill and practice procedure in the…

Explores how to use Gardner's Multiple Intelligence theory to help students' master multiplication. Focuses on helping children use their different intelligence strength to attain conceptual understanding of multiplication, develop their own thinking strategies for harder facts, and build mastery through practice and problem solving.
