A Look at Nets of Cubes
Peer reviewed Peer reviewed
Wardrop, R. F. – Arithmetic Teacher, 1970
Explains a discovery activity using the possible positions of the faces of a cube when represented in two dimensions. Suggests rules which would determine which of the edges would connect if the drawing were folded to form the cube. (RS)

The Versatile Number Line.
Peer reviewed Peer reviewed
Buschman, Larry – Arithmetic Teacher, 1993
Describes an activity that demonstrates a teaching-learning model in which students ask yes or no questions to determine an unknown number on a number line. Provides a sequence of five steps to carry out the activity and suggestions for extending and expanding the activity for different grade levels. (MDH)

Getting the Most from a Problem.
Peer reviewed Peer reviewed
Fulkerson, Paul – Arithmetic Teacher, 1992
Discusses how a single problem can be utilized to discuss mathematical skills and concepts at several different levels. Presents a problem involving fractions examined at the following four levels according to the abilities of the students: (1) finding solutions; (2) identifying methods for finding solutions; (3) exploring similar examples; and…

See It, Change It, Reason It Out.
Peer reviewed Peer reviewed
Shaw, Jean M. – Arithmetic Teacher, 1993
Preservice elementary teachers worked cooperatively to explore the relationship between the measure of the central angle and the number of sides of regular polygons using the reflection of a line in a hinged mirror. The experience involved conjecture and experimentation, communication, and building connections between science, geometry, and…

Ideas.
Peer reviewed Peer reviewed
Hopkins, Martha H.; Gard, Diane M. – Arithmetic Teacher, 1992
Describes 4 activities for levels K-2, 3-5, 4-6, and 6-8 and a family activity that asks students to describe their community; use coordinates to represent the 4 voyages of Columbus; write a story based on a line graph of Lewis and Clark's expedition; determine serving sizes for astronauts in space; and investigate different modes of…

The Number 2 Challenge.
Peer reviewed Peer reviewed
Alterman, Alan E. – Arithmetic Teacher, 1992
Describes the "number 2 arithmetic challenge," an activity in which students score points by creating examples using the number 2 that satisfy an unknown rule. Computers are utilized to verify and record examples. Conflicts with computer responses create situations to explore negative numbers, fractions, mixed numbers, the order of…
