This article describes a lesson unit in which students constructed tables and graphs to represent the growth of different trees. Students then compared the graphs to develop an understanding of slope.

Many teachers bring caterpillars into their class for their students to see the transformation from caterpillar to butterfly. This is exciting and educational, but more can be done using Monarchs across the curriculum. This article describes an integrated butterfly unit for students in grades four to six that starts with identifying the Monarch…

The What Works Clearinghouse (WWC) looked at elementary school math curricula designed to promote math knowledge and skills among elementary school students (average ages 5 to 10 years). Curricula included in this review are replicable, materials-based instructional programs that cover one or more of the following content areas: numbers,…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

One skill that elementary students need to acquire is the ability to analyze spatially distributed data. In this activity students are asked to complete the following tasks: (1) plot a set of data (related to "mud-sharks"--an imaginary fish) on a map of the state of Alabama, (2) identify trends in the data, (3) make graphs using the data…

This computer software program helps to make classroom worksheets, take home assignments, and school mathematics tests easy to design and manufacture. The accompanying printed teaching guide provides technical information for setting up and using the program, along with sample worksheets and instructions on how to create them using the software.…

This investigation into the effects of configural properties (properties determined by the interrelationships existing between component parts) used a selective attention task to determine whether intersection is a primary encoding feature or is constructed after slopes and heights are perceived. The method for encoding feature identification,…

The way that graphs can be used to make calculations that are commonly used by institutional researchers is described using specific examples, and the technique of constructing computational graphs (and nomographs) is outlined. It is shown that once a calculation involving several variables has been represented by a computation diagram or a…

The value of including a unit on graph theory in the elementary school mathematics curriculum is discussed. A module for use in teaching graph theory to elementary school teachers is presented. (SD)

Activities involving set union and intersection, graphing solutions of open sentences, and negation are described. These activities afford students with opportunities for computational practice as well as instruction on equations and inequalities. (SD)

The mathematics of the game "Instant Insanity" is described in terms of graph theory, a part of combinational mathematics. (SD)

This chartbook is designed as a graphic reference on national statistical information about disabilities. Each page contains a content question, explanatory text, and an explanatory chart or table as well as information on sources used. Key terms are shown in boldface and defined in a glossary. Section 1 provides demographic data on Americans with…

Designed as an overview of the progress of middle schools in the last two decades, this document compares results from a 1968 survey that sampled 10 percent of middle schools with at least three, and not more than five grades, and including grades 6 and 7, with those of a similar 1988 survey. Following a brief summary of the origins of the middle…

This paper is a preliminary inquiry by a non-mathematician into graphic methods of sequential planning and ways in which hierarchical analysis and tree structures can be helpful in developing interest in the use of mathematical modeling in the search for creative solutions to real-life problems. Highlights include a discussion of hierarchical…

Based on a study of the book collection of Columbia-Greene Community College Library (New York) carried out in the summer of 1987, this report investigates the relationship of age and previous use to the future use of books. An examination of the acquisition year and circulation records of 10% of the library's book collection (approximately 4,000…
