Platform unique online simulators

This simulator is the initial step in teaching mental arithmetic. This simulator automatically generates examples of any given complexity and a given number of terms. It is recommended to use this simulator from the very first lesson. When children are just beginning to learn simple addition and subtraction, this simulator can be used both when practicing examples on the abacus, replacing a workbook, and when entering mental arithmetic. In the future, it is important to use such a simulator every time the topic becomes more complex. For example, the number of terms increases or new formulas appear.

Working on any topics on addition and subtraction in dynamic mode - when one addend is replaced by another on the screen at a given speed. This simulator is the next step in training for those involved in mental arithmetic after the static one. For students who have mastered mental counting in static mode, as a new training to improve their skills (it is recommended to use voice accompaniment during the first training sessions - this will make counting easier for the student). For students and teachers when it is necessary to increase the speed of counting on the abacus or mentally.

Combinations of abacus beads, from which the student must determine the corresponding numerical value. Suitable for children of zero level. Promotes effective visual training for quick perception of numbers in the form of beads, which is necessary for mental calculation.

It can be used already in preschool age when studying the multiplication table, as well as when practicing the multiplication of multi-digit numbers with given parameters - both on the abacus and mentally.
