This paper, a Southwest Regional Laboratory (SWRL) technical note, contains preliminary guidelines for the development of spelling instruction for kindergarten through grade three. It includes information on program content and organization, word-attack instruction, written exercises, teacher materials, and supplementary activities. The material has been organized into units and sequenced using the following criteria: difficulty, confusability, environmental constraints, frequency, and regularity. The kindergarten program consists of fifteen units, one of which is an introductory phonics unit and two of which are reviews of preceding blocks of material. The remaining twelve units present lessons based on eighteen vowel-consonant elements. In the first-grade program, the original material has been expanded to include seven additional vowel-consonant elements. The second-grade program includes approximately 300 to 350 words, and the third-grade material includes 350 to 400 words. The content of the second- and third-grade programs includes a review of first-grade rules as well as secondary vowel rules, compounds, homophones, suffixes, contractions, numbers, and days of the week.
