Presents teaching methods to rectify the tendency of students and even teachers to divide the smaller number into the larger in problem situations requiring division, while recognizing the impossibility of the answer in the situation. (MDH)

Ability grouping persists because few practical, financially feasible, and politically palatable alternatives have been explored. Built to accommodate a team of 6 teachers and 135 to 150 students, 1 Virginia middle school's parallel block scheduling plan exchanges tracking for a practical method of working with heterogeneous groups of students.…

Presents two sets of calendars for July and August that include simple science or math activities for each day. The first set is for students in grades 3-5; the second set is for middle school students. The activities motivate students to investigate and collect data and reinforce concepts learned in school. (SM)

Presents an alternative method to teaching percent problems which uses a 10x10 grid to help students visualize percents. Offers a means of representing information and suggests different approaches for finding solutions. Includes reproducible student worksheet. (MKR)

Discusses the changes in the scanning of food and the current use of computer technology and UPC bar codes in a grocery store and traces the history of calculating tools from the use of fingers, abacus, slide rule, calculators, and computers. Includes reproducible student activity sheets. (MKR)

Examines how one teacher's way of knowing mathematics was reflected in language used in teaching concepts of rate to one student. The teacher's conceptualizations of rate were encapsulated in the language of numbers and operations which undermined his effort to help the student understand rates conceptually. (Contains 27 references.) (Author/MKR)

Describes a study of the effect of teachers' verbal feedback on the ability of bilingual sixth graders to solve mathematical word problems. Treatment was based on Mayer's model of problem solving. Results indicated that theory-based feedback targeted to bilingual students' individual and class needs improved student mathematics performance. (GH)

Compared the effects of using various computer software programs on the attending behavior of children with attention-deficit hyperactive disorder (ADHD). Found that the attention of ADHD children increased while they used software with a game format when animation was not excessive. Other factors affecting nonattending behaviors included the…

Presents a description of pedagogical content knowledge in mathematics, constructed from interviews with fifth grade teachers; suggests modifications in the general conception of pedagogical content knowledge based on this description, and suggests revisions in teacher education practices to improve teachers' understanding of pedagogical content…

Describes a unit of study for gifted fifth graders that connects architecture to the content areas of history, mathematics, and science. Emphasis was on problem solving of real-world problems as recommended in major reports on mathematics instruction. The unit also used technology in innovative ways, including computer-drawn images and digital…

Presents activities on estimation, scaling, area of nonstandard shapes, algebraic thinking, and real-life situations using the United States of America. These activities make it possible to integrate mathematics and social studies. Uses technology by employing geometry software packages such as The Geometer's Sketchpad, Cabri, and Geometric…

Describes several short geometry tasks that go beyond the simple recognition of figures and properties. Presents scoring rubrics and questions that might be useful to middle school teachers developing short open-ended questions that encourage and assess students' thinking. (ASK)

Students receiving mathematics instruction relevant to life will understand that mathematics is part of the real world and not just another school subject. Presents an activity that integrates rational numbers with health-related science content as students collect data and engage in decision making. (ASK)

Six fifth-grade students with learning and/or behavioral/emotional disabilities received peer tutoring on multiplication and division facts using 3 drill and practice conditions varying in the ratio of unknown to known facts (30:70, 50:50, and 70:30). Five of the students mastered facts at a faster rate in the 70% unknown/30% known condition. (DB)

Reports on a pilot study that examined use by sixth-grade students in Costa Rica of a mathematical microworld written in LOGO. The investigation had three phases: (1) open exploration of the microworld; (2) group discussion and sharing of hypotheses; and (3) guided discovery and problem solving. (Contains 11 references.)
