The concept of numbers is forming in early childhood. Interactive exercises on comparison of numbers up to 20 are offered to develop the comparison habit in primary school age children.
The «Blackboard» application includes exercises to use “greater “, “less” or “equal” signs. It is intended to teach children to solve equalities and inequalities.
All exercises are grouped by 6 levels of complexity.
Mathematical “Blackboard” is a good foundation for intellectual development of primary school children- the pupils learn to solve, memorize and compare the calculation.
