The purpose of this study was to develop and validate an assessment tool entitled the Algebra Curriculum Based Measure (ACBM) with the intent of measuring preschool children's sorting and classifying skills based on one attribute (color, shape, and size) and two attributes (color and shape) simultaneously; and their ability to explain their sorting and classifying strategies. The hypothesis was that five sub-constructs, namely, "Color," "Shape," "Size," "Color and Shape," and "Explanation," would significantly contribute to the latent construct sorting and classifying. The ACBM was administered to 120 preschool children enrolled in accredited child care centers in Cincinnati, Ohio, during the 2012-2013 school year. A Confirmatory Factor Analysis (CFA) was used to measure the hypothesized model with raw and square root transformed data. Results indicated a good model fit between the hypothesized and measured models in both cases: ?[superscript 2]; (2, N = 120) = 0.882, p = 0.643; NFI =.992; CFI = 1.000; and RMSEA = 0.000 with raw data, and ?[superscript 2]; (2, N = 120) = 0.749, p = 0.688; NFI =0.992; CFI = 1.000; and RMSEA = 0.000 with transformed data. While factor loadings obtained with raw data ranged from 0.43 to 0.69, factor loadings obtained with transformed data ranged from 0.44 to 0.63. All standardized path coefficients demonstrated both statistical significance at the 0.001 level (2-tailed) and practical significance (beta > 0.3) in both cases. The conclusion was that the ACBM is a valid and reliable assessment tool of sorting and classifying for this sample of preschool children.
