When performing numerical operation, the child only needs to press the snap joint slightly, and then the operation member 21 with the numeral symbol or the operation symbol can be connected to the cylindrical bar 22, and the desired numerical operation expression can be arranged. The snap joint and the cylindrical bar 22 are connected in a clamping manner, so that the training is more efficient and interesting.

[0079] Preferably, the bottom end of the throwing assembly is provided with a support column 24; the display board 20 is internally provided with a straight rail; the straight rail is slidably connected with a connecting column 23; the connecting column 23 is rotatably connected with the support column 24 at the end away from the display board 20.

[0080] Specifically, as shown in Figure 1 and Figure 2 The display board 20 is specifically designed as a box structure around the periphery. When in use, the connecting column 23 is slid along the straight rail, the other end is rotated around the support column 24 to expand the display board 20 into a use state. When not in use, the connecting column 23 is slid into the display board 20, and the connecting column 23 is rotated around the support column 24 to make the display board 20 into a row, reducing the space occupied by the display board 20, and the storage is stronger, and the display board 20 is convenient to carry.

[0081] Preferably, the top end of the support column 24 is provided with a launching assembly; the throwing assembly is arranged at the top end of the launching assembly; the launching assembly is internally provided with a containing bin 312.

[0082] The containing bin 312 can be seen after the launching assembly is opened, and the containing bin 312 can be placed with items related to the game, such as an indicator, a record table or a prize. The launching assembly can make the containing bin 312 in a relatively isolated environment from the outside world, preventing the items in the containing bin 312 from being lost. The launching assembly is used to connect the throwing assembly with the support column 24, which is also conducive to increasing the interest of the teaching aid and attracting the attention of children.

[0083] Preferably, the ejection assembly includes: an upper cover 30 and a lower cover 31; the throwing assembly is disposed on the upper cover 30; the receiving compartment 312 is disposed on the lower cover 31; the bottom end of the lower cover 31 is connected to the support column 24; one side of the upper cover 30 is hinged to the lower cover 31, and the opposite side is provided with an ejection buckle that engages or disengages with the lower cover 31.

[0084] When an item needs to be retrieved from the storage compartment 312, the ejector latch is engaged, causing the upper cover 30 to rotate and separate from the lower cover 31 around the hinge edge, revealing the storage compartment 312 located on the lower cover 31. The stored item can then be retrieved. This ejection-based opening mechanism for the storage compartment 312 attracts children's attention through dynamic visual effects, enhancing the fun of the game, embodying the educational philosophy of learning through play, and increasing children's participation. Specifically, for example... Figure 4 As shown, the outer side of the snap-fit ​​end of the lower cover 31 is movably connected to the middle of an opening button 32 via a movable hinge 6. A compression spring 313 is provided between the lower part of the opening button 32 and the lower cover 31. A hook 301 is formed on the outer side of the snap-fit ​​end of the upper cover 30. The upper part of the opening button 32 is provided with a hook engagement part 321 that matches the hook 301. The snap-fit ​​end of the upper cover 30 is located on the lower side of the hook 301 and forms two opposing claws 302. Each side of the opening button 32 is provided with a claw engagement part 322 that matches the two claws 302. The lid opening button 32 rotates around the movable hinge 311 to put the upper and lower lids 31 into a locked, half-open, or open state. When the lid is locked, the hook 301 engages with the hook engagement part 321. Pressing the lower part of the lid opening button 32 inward causes the hook engagement part 321 on the lid opening button 32 to rotate outward and disengage from the hook 301. At the same time, the claw engagement part 322 also rotates outward and engages with the claw, thus putting the lid in a half-open state. Releasing the lid opening button 32 causes the claw engagement part 322 to rotate inward and disengage from the claw 302, putting the lid in the open state, allowing the item in the storage compartment 312 to be removed. The storage compartment 312 is located inside the lower lid 31 and opened by a spring-loaded mechanism, further enhancing the fun of the game.
