With an innovative design of the plastic tokens that fit together and are printed with whole numbers, fractions and arithmetic signs, LADO has developed a method for mental calculation exercises.
This method allows to maintain interest and attention, while basic arithmetic operations are put into practice. It provides a nice way to consolidate the operating mechanisms of the calculation.
Content: 108 cards: 60 whole numbers, 12 fractions (1/2,1/4, 3/4 and 4/4), 36 arithmetic signs (+,-,x,:,>,<) and 13 symbolic drawings of fractions.
