Essential Mathematics
by D. Franklin Wright
Essential Mathematics provides students with a learning tool that will help them develop basic arithmetic skills, develop reasoning and problemsolving skills, and achieve satisfaction in learning so that they will be encouraged to continue their education in mathematics. The style of writing gives carefully worded, thorough explanations that are direct, easy to understand, and mathematically accurate. The use of color, subheadings, and shaded boxes helps students understand and reference important topics.
Students are expected to participate actively by working margin exercises and completion examples as they progress through each section. The answers to the margin exercises are in the back of the text, and the answers to the completion examples are at the end of each section. This approach provides the students with immediate reinforcement and the instructor with immediate feedback as to how well the students understand the material. Space is provided in the text for students to calculate and write answers on the text page.
The text’s flexible style allows for teaching based on the standard lecture method and for programs based on the cooperative learning (small group studies) or independent study in a mathematics laboratory setting. The NCTM and AMATYC curriculum standards have been taken into consideration in the development of topics.
