Describes some square-number patterns that fourth-grade students and their teacher discovered. These discoveries began as students pushed wooden cubes together to make square arrangements. (JN)

Demonstrates the use of the memory functions on hand-held calculators by presenting three activities that are appropriate for use in middle grades (4-8). The constant arithmetic feature of the calculator is also required. (JN)

Following a brief introduction to the LOGO programing language, describes its use in a sixth-grade classroom. The situations described illustrate students' growth while the choice of the situations illustrates teachers' growth. (JN)

Several experiences with palindrome numbers are given, each leading to the "Law of 11." Conjectures for the reader to consider are included. (MNS)

Suggestions for using a computer disc containing unprotected programs are given. The Fibonacci sequence, prime factorization, sum puzzlers, and other examples are described. (MNS)

Describes an activity approach for teaching upper elementary school students the concept of angles. In the interdisciplinary activity, students practice reading and drawing angles from 0 to 360 degrees as they simulate the behaviors used to navigate a sailboat. Includes list of equipment needed and procedures used. (JN)

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…

Outlined is an interdisciplinary unit on statistics. Discussed are the goals, organization, the preinstruction survey, the math lessons, results, and evaluation. The survey and examples of the students' work are provided. (CW)

Presents a problem to produce a chart in which a driver can look up the time in seconds it took to travel one mile and find out how fast the car was traveling in miles per hour. Several programs to solve the problem are listed and discussed. (JN)

Discusses ways to simulate a probability problem of interest to middle school students in which students calculate the average number of packets of trading cards purchased to obtain a complete set of cards. Simulations utilize a spinner, a table of random numbers, and a computer. Includes the BASIC program utilized in the simulation. (MDH)

Describes the formation and organization of a mathematics club for fourth- and fifth-grade students. Offers 12 hints on running a successful club based on the author's experiences. (MDH)

Outlines steps necessary for students to learn how to use one another as resources for doing mathematics, including preparation for group work, fine tuning communication and cooperation skills, and developing helping skills. Includes a "good helper" and "good help receiver" checklist. (Contains 14 references.) (MKR)

Described is the Delaware Elementary Mathematics League; a state mathematics competition for grades 4-6. Included are specific sample test items and a discussion of how they can nurture the development of problem-solving skills. Sample tests are also discussed. (CW)

Discusses a children's television show, "The Math Connection," which shows connections between mathematics and daily pursuits of local workers and tries to affect attitudes of students and teachers toward mathematics. Describes the content and structure and the open-ended problems on which students work to prepare for the show. (MKR)

Describes an approach which helps sixth-grade students become excited about word problems. By using the approach (which involves categorizing a problem before solving it), students master skills in the problem and also develop more positive attitudes toward solving problems. The approach is equally applicable to any intermediate/junior high grade…
