Embodiment 1
[0031] Such as Figure 1-Figure 6 As shown, the educational teaching aid used to enhance children's ability to recognize shapes in the present invention includes a base 1 and an insert block 3, and a mounting hole group I is provided on the upper surface of the base 1, and the mounting hole group I includes a number of different shapes. The installation hole 2, the number of the plug-in block 3 is consistent with the number of the installation hole 2, and one plug-in block 3 corresponds to one installation hole 2, and the cross-sectional size of the plug-in block 3 is consistent with the cross-sectional size of the corresponding installation hole 2, One end of the insert block 3 is located in its corresponding mounting hole 2;
[0032] Limiting blocks 4 are arranged at the bottom of the mounting hole 2, and a groove 5 is arranged on the end of the plug-in block 3 near the bottom of the hole. match the cross-sectional dimensions. And each plug-in block 3 can only be put into ...
Embodiment 2
[0041] Such as Figure 7 As shown, this embodiment is based on Embodiment 1 to further illustrate the present invention.
[0042] When the plug-in block 3 is located in the mounting hole 2, the metal sheet 8 of the circular mounting hole 2 in the mounting hole group I, the metal sheet 8 of the circular mounting hole 2 in the mounting hole group II, and the mounting hole can be connected by wires. The metal sheet 8, metal ring 7, power supply 9 and acousto-optic device 10 of the circular mounting hole 2 in group III are connected in series to form a complete circuit, such as Figure 7 shown. At this time, when the child successfully places the plugs 3 that are all circular, the activation of the acousto-optic device 10 can be triggered.
[0043] And the metal sheets 8 of the mounting holes 2 of other corresponding shapes can be connected in the above-mentioned manner in turn.
