This curriculum guide was developed for low achievers and students needing special programs in first-grade mathematics. Modeled after the "Science--A Process Approach" curriculum, the program consists of an integrated series of learning activities. Master worksheets for recommended activities are included in the guide. The curriculum is divided into ten units. The first unit deals with the concept of numerosity and with the first three (whole) numbers. Subsequent units each deal with a single whole number. Activities involve printing the numeral as well as associating the numeral with appropriate sets. A list of objectives and pre- and post-tests are provided for each unit. (SD)
