Focuses on student organization, preparation, and presentation of simple foods (beverage, brownies, sloppy-joe sandwiches) as a way to apply various mathematical concepts, with problem-solving techniques being central to almost all the activities. Includes reproducible student worksheets. (MKR)

Manipulative materials designed to instruct pupils on fractions are presented. The use of unit holders in teaching fundamental concepts of fractions and equivalent fractions are reviewed. (MP)

Presents a unit of study involving tangrams that integrates geometric relationships, scale drawings, graphing, patterns, and logical thinking. Provides worksheets for independent and cooperative activities to discover geometric shapes using a specified number of tangram pieces. (MDH)

To develop students' abilities to reason with mathematics and apply mathematics to problem solving are abetted by building on their personal experiences, integrating the curricula, and designing learning activities that require students to write or speak about mathematics. Using an integrated approach is discussed and examples are included. (MNS)

Five different triangle shapes cut from poster board or construction paper provide the springboard for student activities and discussions of a variety of geometric concepts from kindergarten to grade 8. (MP)

Presents 5 activities for the K-1, 2-3, 4-5, 6-8 grade levels and for in the home in which students explore the concept of combinations. Each activity includes a lesson plan to investigate a combinatorics problem appropriate for that grade level. Provides reproducible worksheets. (MDH)

Describes an eight-day graphing unit for grades four through six using data collected from a local cemetery. Provides the activities of each day and excerpts of discussions taking place during the lessons. Concludes that working with real data helps students construct meaningful graphs. (MDH)

Some reasons why simple ideas in projective geometry should have a place in the elementary school curriculum are suggested. Then, seven lessons on projective geometry that were taught to a class of 10-year-olds are described. (MNS)

Suggested is a format for sequencing instructional activities during the typical elementary school mathematics period to elicit better teaching and more learning. To illustrate each component of the format, a lesson on fractions appropriate for fourth or fifth grade is outlined. (CW)

Introductory and follow-up activities with Iggies, a tool for teaching and reinforcing the ability to discern likenesses and differences, are given. Two lessons for kindergartners are detailed, and some suggestions for other uses of Iggies are noted. (MNS)

Presented are worksheets designed to provide experience in identifying, discriminating, and drawing geometric shapes; introduce area approximation or irregularly shaped figures; provide practice in estimating and determining areas of irregular plane regions; and provide experiences in making tile designs. (MP)

A teaching sequence for the division algorithm is detailed. (MP)

A variety of techniques and procedures is discussed, focusing on the need to know children, to know mathematics, and to find workable methods for involving one with the other. A tag system'' for classifying the type of things taught in mathematics, planning for daily learning experiences, and involvement, investigation, and questioning techniques…

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)

A useful approach for developing insights and discovering patterns is to examine numbers in relation to the number of their divisors. A teaching procedure for this approach is presented, with questions, answers, and homework suggestions. (MNS)
