This study investigated the accuracy of three fraction measures (i.e., fraction number line estimation accuracy, general fraction concepts, and fraction arithmetic) for screening fourth graders who might be at risk for mathematics difficulties. Receiver operating characteristic (ROC) curve analyses assessed diagnostic accuracy of the fraction…

The National Mathematics Advisory Panel specifies that children should be able to fluently add and subtract whole numbers by the end of third grade. Mathematical understanding of addition and subtraction emerges well before formal mathematic instruction begins, and when it emerges it reflects competence in a number of prerequisite skills and…

Developmental predictors of children's fraction concepts and procedures at the end of fourth grade were investigated in a 2-year longitudinal study. Participants were 357 children who started the study in third grade. Attentive behavior, language, nonverbal reasoning, number line estimation, calculation fluency, and reading fluency each…

THESE GUIDELINES FOR CLASSROOM TEACHERS OFFER SUGGESTIONS FOR TEACHING ELEMENTARY SCHOOL MATHEMATICS IN A MANNER TO REFLECT RECENT CHANGES IN CONTENT, TECHNIQUES, AND APPROACHES TO TEACHING MATHEMATICS. THE PURPOSES OF THESE GUIDELINES ARE (1) TO DETERMINE A DIRECTION FOR MATHEMATICS EDUCATION IN THE ELEMENTARY SCHOOLS OF DELAWARE, (2) TO PROVIDE…

THE PURPOSE OF SYSTEMATIC TEACHING AND LEARNING IN ARITHMETIC IS TO HELP CHILDREN DEVELOP IDEAS OF PROCEDURE, METHODS OF THINKING, MEANING INHERENT IN NUMBER REACTIONS AND ARRANGEMENT IN ORDER THAT THE QUANTITATIVE SITUATIONS OF LIFE MAY BE HANDLED INTELLIGENTLY. AT THE KINDERGARTEN-PRIMARY LEVEL THE NUMBER CONCEPTS TO BE FOSTERED ARE--PUTTING…

Described is the Delaware Elementary Mathematics League; a state mathematics competition for grades 4-6. Included are specific sample test items and a discussion of how they can nurture the development of problem-solving skills. Sample tests are also discussed. (CW)

The study of the public-school system of Wilmington, Delaware, of which this bulletin is a part, was made by the United States Commissioner of Education upon invitation of a committee of 30 citizens of Wilmington appointed by the board of education, by the city council, and by the mayor of the city, and empowered to arrange for such a study. In…
