特徴とする乗法九九練習機。 It has a coaxial and relatively rotatable multiplier plate and a multiplicand plate that is larger than the multiplier plate, and the multiplier plate has nine equal directions arranged in the same direction and one of the numbers from 1 to 9 of the multiplier of the multiplication table. The multiplicand board displays the multiplicand board by distributing and displaying any one number from 1 to 9 as the multiplicand of the multiplication table by distributing 9 equal numbers in the circumferential direction around the multiplier board. In addition, all the products of one multiplicand and each multiplier from 1 to 9 shown on the multiplicand board are displayed on the outside of each multiplicand, and the multiplicand board is provided with nine switch contacts corresponding to the multipliers. Nine switch contacts are provided corresponding to each of the multiplicands, and an external contact for a pentouch that can be operated from the outside is attached to each display of the product of the multiplicand plate, and the switch contacts corresponding to the multiplicands of the multiplicand board and the multiplicand are provided. and 1-9
Wiring is done between the external contacts attached to the display of the product of the multipliers up to, and each switch contact on the multiplier plate corresponds 1:1 with the nine switch contacts provided corresponding to the multiplicand on the multiplicand board without duplication. A common touch pen is provided at the tip of the wire to act on the external contact for the pen touch, and the touch pen is connected to the external contact for the touch touch. A multiplication table training machine characterized in that a display device is interposed in a circuit that closes when the circuit contacts the multiplication table.
