Research has shown that integrated computer activities can increase achievement, particularly in the areas of mathematics and science. Connect4Learning: The Pre-K Curriculum includes a series of computer learning activities designed to address learning trajectories in mathematics and to solidify classroom learning. Through practice and repetition of early mathematics concepts, these games help children foster deeper conceptual thinking and develop competence in key skills, such as counting and sorting. Each game corresponds to a given unit and lessons within the curriculum. The difficulty of each game increases as children's abilities progress.
