A program of mathematics instruction for grade one is provided in this curriculum guide. The teaching goal of each lesson is stated in the Purpose section. Visual aids and manipulative materials useful in developing each lesson are suggested and additional teaching aids are listed. Suggestions for teaching the lessons are separated into three distinct categories: Prebook Activities, Using the Page, and Postbook Activities. Selected activities that provide greater challenge for those pupils who excel are included. Each unit concludes with a self-evaluation page entitled Checkup Time. Additional reviews and tests are also written for each unit. Topics covered are: elementary number concepts; sets and one-to-one matching; cardinal numbers and numerals 0-9; addition and subtraction combinations through nine; simple concepts of fractions; measurement and geometrical concepts; operations with tens; measurement and number patterns; and some addition and subtraction using place value. A time budget chart lists the recommended pace for completion of the proposed curriculum. (JP)
