The “Bilisius” game fosters child’s ability to quickly identify the larger set of colored marbles without counting. The child becomes a magician who sidewalks and tries to solve exercises. The child sees a cluster of two sets of yellow and blue marbles and has to quickly decide (without having enough time to count) which set has more marbles than the other by moving the body left or right to the appropriate colored small carpet.
The teacher/therapist can choose whether the marbles of different colors will have the same size or not as well as total number of marbles that will be shown to the child. The more marbles (up to 20) can appear the more difficult the game becomes.
Also, the teacher/therapist can choose whether there will be game lives and an active timer. This game strengthens the children’s visual perception, promotes the ability to make rapid, accurate, and confident judgments.
