[0018] Figure 2 This is a back view of a learning ruler used for teaching the comparison of number sizes, according to a preferred embodiment of this utility model. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] The preferred embodiment of this utility model is a learning ruler for teaching the comparison of number sizes, such as... Figure 1 As shown, see also Figure 2 The system includes a long, narrow ruler body 1 and a support frame 2 supporting the ruler body. The ruler body 1 is suspended in the air under the support of the support frame 2. Scale markings 10 are provided on the ruler body 1 along its length. A first arrow marking 11 for indicating the scale markings is slidably provided on the upper edge of the ruler body 1, and a second arrow marking 12 for indicating the scale markings is slidably provided on the lower edge of the ruler body 1. A number plate 3 with adjustable digit size and a flipping unit 4 for flipping the number plate are provided on the back of the ruler body 1. The number plate 3 has a first state facing the front of the ruler body 1 and a second state facing the rear of the ruler body 1 under the flipping action of the flipping unit 4.
[0021] When in use, the referee (a teacher or student) can change the number on the number card 3, keeping the number card 3 facing away from the front of the ruler body 1. Multiple students guess the number, and the first arrow marker 11 and the second arrow marker 12 are adjusted according to the guessed number to narrow down the range of numbers to be selected. The game ends when a student guesses the correct number on the number card 3. The flipping unit 4 flips the number card 3 to reveal the answer. This method allows students to learn about comparing the size of numbers in an entertaining way, which is more interesting and easier for students to accept.
[0022] Taking the number 3 with the number 54 and the scale range of the 10 mark as 0-100 as an example, in the initial state, the first arrow mark 11 is located at the 100 mark and the second arrow mark 12 is located at the 0 mark. When the first student guesses 78, the first arrow mark 11 is moved to 78. When the second student guesses 39, the second arrow mark 12 is moved to 39 (during which time the referee can give hints: whether the guessed number is too big or too small). This process is repeated to gradually reduce the distance between the first arrow mark 11 and the second arrow mark 12 until the number 54 is guessed, and the game ends.
[0023] Preferably, the support frame 2 includes a long strip-shaped base 20, with uprights 21 at both ends of the base. The two ends of the ruler body 1 are detachably connected to the upper ends of the two uprights 21. The upper end of the uprights 21 is provided with a positioning groove for positioning the ruler body 1, and a screw hole is provided at the bottom of the positioning groove. The ruler body 1 is movably provided with a hand-tightening screw 13 that engages with the screw hole for locking. During installation, the ruler body 1 is placed into the positioning groove for positioning and fixed by the hand-tightening screw 13 to complete the assembly.
[0024] Preferably, the upright 21 and the base 20 can also be foldable or detachable so that the entire device can be stored when not in use.
[0025] Preferably, the number card 3 includes a stand plate 30, one side surface of which is provided with a placement groove 31 for placing the number card 32 (the placement groove can be formed by setting a pocket), and the other side surface of the stand plate 30 is connected to the movable end of the flipping unit 4; the structure is simple, and it is convenient to quickly change the numbers by changing the number card 32, which is low in cost.
[0026] Preferably, the flipping unit 4 includes a longitudinally oriented flipping shaft 40 (which is set with a certain gap from the ruler body 1 so that the first slider 15 can pass through). The flipping shaft 40 is connected to the back of the ruler body 1 by a damping rotating shaft 41. The other side surface of the upright plate 30 is fixedly connected to the upper end of the flipping shaft 40. The structure is simple and convenient to quickly change the state of the number plate 3 by rotating the upright plate 30. The cost is low.
[0027] Preferably, the base 20 is equipped with a storage box 200 for storing the number playing cards 32, which is convenient to use;
[0028] Preferably, the base 20 is also equipped with a sound generator 201, a power supply 202, a switch 203, and a light effect lamp 204, which are connected in series to form a circuit; preferably, the base 20 is equipped with a gift box 205; this part is an optional component used to reward the winner with sound effects, light effects, and gifts to enhance students' learning enthusiasm.
