A list of heuristics for elementary school children is provided. Two examples which are viewed to demonstrate the conscientious and creative use of problem-solving strategies by fourth graders are detailed. Suggestions for teachers on how to help pupils develop their problem-solving abilities are included. (MP)

Described are children's strategies in thinking about fraction order and equivalence. The data are based on two teaching experiments with fourth and fifth-grade children. Some sample activities for teaching order and equivalence are included. (RH)

Fourth-grade students in Title I mathematics took 40-problem tests to determine types of persistent errors made in addition and subtraction. Tests, administered to 117 students (addition) and 104 students (subtraction), were analyzed for basic fact, random, or procedural errors. Findings are reported and discussed, and recommendations for…

A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

A project to tempt students to pose questions, state hypotheses, measure, estimate, compute, and evaluate their answers in terms of a problem they can see and manipulate is described. Selecting landmarks, collecting data, developing a blueprint, interior decoration, and fabrication are among the points discussed. (MNS)

The way that fractions are taught to fourth-grade pupils at the Village Community School in New York City is detailed. The approach is thought to make the often frightening symbols of fractions into something that even beginning students find meaningful. Meaning rather than computational technique is emphasized. (MP)

Describes a problem formulated by fourth-grade students about having more pizza for lunch, and the clarifying, predicting, modeling, simulating, comparing, and extending activities that occurred in addressing the problem from a probabilistic perspective. (MKR)

Describes a number line created by fourth-grade students containing paper rectangles to represent the basic multiplication facts. The use of this number line can help students to understand factoring, prime and composite numbers, and beginning fraction concepts. (MKR)

A lesson using Logo was found to be effective when working with concepts of division. It emphasizes relationships between arithmetic and geometry in a novel way, and has been used with students in grades two and four. (MNS)

Data are presented for problem-solving content of selected elementary school mathematics textbooks and problem-solving achievement for students in Iowa for grades 4-6 for selected years between 1955 and 1985. Relationships between textbook content and student achievement are considered. (RH)

A minicourse designed to teach fourth and fifth graders about computers included decoding computer cards, a "race" against the computer, a field trip, flow charting, and writing computer programs. The course was limited by the students' ability to understand abstract mathematical concepts. (MP)
