The book you are holding is an extremely useful tool for anyone interested in mathematical development and its support in preschool and early school age.

It presents not only findings from the most recent research on mathematics learning in young children but also the most effective methods for teaching mathematics, helping young children develop basic mathematical knowledge from an early age.

On its pages, authors Douglas Clements and Julie Sarama, having conducted years of research on mathematics for preschool and early school age, describe learning and teaching trajectories that outline the developmental path in all thematic areas related to mathematics curricula.

At the same time, they present a wide variety of tested activities that can support mathematics learning in preschool and early school age.
