On one hand, they help to absorbCollect and subtract, and from the other .multiplication and divisionby visualizing the connections between the numbers and facilitating the understanding of mathematical dependencies.Thanks todry-erased surfacestudents can repeatedly record, delete and solve tasks that promote the exercise, building confidence and automation of major mathematical operations.The kit supports the development ofnumerical thinking, building mathematical dependencies, composing equations, logical thinking and problem solving skills. It is suitable for working with small groups, study centers, individual exercises and daily practice.Each board has an approximate size25.4 cm (10')which makes it convenient to use a desk, at home or during additional activities.
