Methods of determining probabilities of various outcomes of the game Yahtzee are described. (SD)

A game modelled on football can be used to provide students with practice in solving algebraic equations. (SD)

Several games, which can be useful in the classroom for teaching problem solving strategies, are described. (SD)

Many fundamental geometric figures can not be constructed on the familiar square geoboard (e.g., equilateral triangle, regular hexagon). Activities which can be used with an isometric geoboard for study of these figures are catalogued. (SD)

The authors develop some necessary considerations for evaluating mathematical games as well as provide some examples of quality games. (MN)

An approach to problem solving broader than the traditional one most often used by instructors is described and recommended. Implementation of these ideas has the potential of increasing problem solving ability of students while promoting a fuller appreciation of the value of the process. (MP)

Organizing, storing, and using materials for classroom games are discussed. Materials and directions are listed for three strategy games, three whole number games, three fraction games, and three geometry games. (DT)

Discussed is the status of textbooks in science instruction. Described are ways in which teachers can use the textbook more effectively. A multilevel approach to science textbooks is described. A list of easy-reading science textbooks for earth, general, and physical science is included. (KR)

Presents a practical model for planning and implementing a field trip as an integral part of the science curriculum. Reviews the literature related to the role of field trips in the learning process; describes the model; and provides an example implementing the learning cycle method. (Contains 17 references.) (MDH)

Instructions are given for a first graders' science and mathematical lesson entitled: "Stone Soup" (based on a popular story by Marcia Brown). Activities include reading, discussing, collecting materials, cooking, growing plants, and observing physical and chemical changes. (CR)

A series of modules designed for teaching energy concepts in a manner related to the classroom, school, and environmental settings is presented. The unit is seen as able to provide both teachers and students with a concept which has far-reaching implications. (MP)

Improvements in the mechanism of the whirlybird used in the Science Curriculum Improvement Study (SCIS) unit "Subsystems and Variables" are presented. Variables which can be investigated using this device are discussed. An illustration of the improved device is provided. (CW)

Presents a study to examine the effects of a verbal teaching strategy versus a strategy providing instruction using activities and manipulatives in four seventh grade earth science classes with students of varying cognitive abilities (n=83). Results indicate that students with more cognitive structures perform better and that using manipulatives…
