Korbo bricks are an effective tool for teaching mathematics. They allow teachers to create dynamic and engaging lessons that help students understand difficult mathematical concepts in a visual and practical way. Korbo as a concrete can be used in lessons practising, among others: multiplication with one factor, operations with crossing the decimal threshold, values of numbers and their sums, reading coordinate points, horizontal and vertical planes, addition and subtraction in bars, reading and writing multi-digit numbers and much more.
