Teno - The Fun Foundation of Quick Mental Calculation
When a child enjoys an activity, he automatically becomes more focused, which is the basis of all learning.
Teno has a set of 110 cards with digits from 0 to 10 (10 cards of each digit). Using these cards a variety of games have been created to help children do quick mental calculations.
Though the main operation used is 'addition', there are games which involve all 3 operations i.e. addition, subtraction, multiplication. Children enjoy these games very much and learn to do these operations mentally with ease and speed.
