This first in a series on the programable calculator presents a chapter on the basic operations. The series is written for a particular calculator, Hewlett-Packard's HP-25. (MP)

Presents a problem involving fractions for discussing and sharing of student responses to the problem at a later date. (KHR)

An approach to the teaching of steady-state recycle calculations is presented. Included are the solutions to two sample problems. (BB)

The relationship between simple interest and compound interest is explored by using calculators to develop the required formula inductively and intuitively. (MP)

The technique of organizing data in tables to solve counting problems in geometry is illustrated in the solution of five problems. (MN)

This heat transfer problem requires students to analyze the feasibility of moving icebergs from the Antarctic to Saudi Arabia to provide fresh water. (BB)

This problem requires the student to calculate the volume of air breathed by a bicyclist every hour in Denver, Colorado, and New York City. (BB)

These student worksheets include activities in counting, place value, estimation, the four operations with whole numbers, number patterns, volume, inequalities, decimal equivalents of fractions, and percents, all to be worked with a calculator. (MP)

Five different ways are outlined in which calculators can be used to develop a student's ability: (1) to solve problems which use real-world data; (2) for solving a greater number of standard word problems; (3) for using different approaches to solve problems; (4) for extending problem situations; and (5) for using the calculator in an…

Many problems and activities which can be worked with a calculator are contained in this booklet. The problems include: pattern recognition, combinations of operations, estimation, squares and square roots, rate problems, area, and volume. Chapter topics include: getting to know the calculator, single-step problems, using formulas, and…

Three worksheets dealing with number triangles are given. Exercises are designed to lead students to discover number patterns within the triangles. (MP)

Describes a take-home exam story problem based on stoichiometry. Requires the student to determine the percentage of phosphoric acid in a large container of nitric acid if a man fell into it. Provides assumptions, clues, and an acceptable solution. (MVL)

This project was based on recent interview research which suggested that in choosing operations for story problems in mathematics many students are guided by computational considerations rather than meanings for the operations. This project aimed to refine the catalogue of strategies used by students and to design and test instructional materials…
