The Calculators and Mathematics Project, Los Angeles (CAMP-LA), funded by the National Science Foundation for developing use of technology in the classroom, developed curriculum materials focused solely on the use of calculators in three stages. The first stage studied the mathematics curricula from different states and identified topics that are not included but should be if every student had a calculator, topics treated in too much detail, and topics no longer appropriate. Based on this information, CAMP-LA compiled a prototype curriculum organized by grade level to be consistent with the "California Mathematic Framework" strands. The second stage developed lessons by classroom teachers to cover the topics. The lessons were divided into four levels: Grades K-2, Grades 3-4, Grades 5-6, and Grades 7-8. The third stage field tested these lessons in various parts of the country. This book is composed of lesson samples from books 1-4 in the series. The introduction gives an overview of CAMP-LA, information on how to use the lesson plans, a glossary of calculator terminology, special features of the calculator, calculator limitations, and a discussion of assessment approaches, with sample assessment items appearing at the end of the book. The remainder of the book is composed of 16 lessons from the four levels. Each lesson is broken down into three sections. The three sections are labeled: "Grade", including grade level, strand, skill required, and purpose; "Management", including class organization, time frame, materials needed, vocabulary, and prerequisite skills; and "Lesson" including suggestions for directed instruction, guided practice, independent practice, evaluation, and home activity.
