Interactive whiteboards are somewhat unimpressive at first and look like the whiteboards that already hang on the walls of many classrooms. However, integrating interactive whiteboard technology in a unit on adding and subtracting integers enhances student engagement and understanding. In this article, the author describes how she used an…

Diverse contexts such as "take away," comparison," and "completion" give rise to subtraction problems. The take-away interpretation of subtraction has been explored using two-colored chips to help students understand addition and subtraction of integers. This article illustrates how the difference and completion (or missing addend) interpretations…

A conceptual knowledge of numbers, especially fractions, is an important link to a conceptual understanding of variables. This article suggests activities that explicitly show the connections between numbers and variables using the number line as the connecting device. (Contains 7 figures and a bibliography.)

The addition and subtraction of integers is the first major avenue, and roadblock, to student success in learning algebra. This article describes a hands-on activity using a regular deck of playing cards that facilitates class discussion and helps students overcome this initial roadblock. (Contains 14 figures.)

Discusses number patterns and Fibonacci numbers found in nature. (YDS)

Uses number sense to involve students in calendar activities based on the Julian and Gregorian calendars. (YDS)

Explores prime numbers and their connections to related topics. (YDS)

Describes an activity in which students investigate patterns and discrete mathematics found in telephone numbers. (YDS)

Describes how the human body can be used to make sense of various number patterns and relationships. (YDS)

Defines number sense and gives suggestions and activities for teachers to use in helping students develop number sense, including using process questions, using writing assignments, encouraging invented methods, using appropriate calculation tools, helping students establish benchmarks, and promoting internal questioning. (MKR)

Describes a prime-number unit that targets middle school students learning about patterns, formulas, and large numbers while participating in a search for the largest prime number. (YDS)
