Today, math is considered to be a special subject in preschool because of its relationship to students´ processes of learning and development. When children start preschool, they already possess the early knowledge, experience and ability that form the basis for further learning. With this in mind, guided math studies at the preschool stage seek to reinforce and expand learners´ acquisition, allowing them to reach a certain level of aptitude, understanding and ability before moving on to the development of more complex concepts. In order to organize and focus early math studies, Richmond Publishing presents the I can do math! series for preschool children. Level B of I can do math! is organized into eleven distinct areas in accordance with the developmental characteristics of the corresponding age group. These areas are colors, shapes, sizes, positions, logical reasoning, quantifying, grouping, logical sequences, numbers, numerical series and addition.
