Abstract

The invention discloses a vertical counter for experimental teaching, which comprises a counter base, a digital display board and a mounting rod. A counting baffle is arranged in the middle of the upper surface of the counter base, and a pen holder is arranged on one side of the counting baffle. There are five mounting rods in total, and the five mounting rods are respectively installed on the upper surface of the counter base, and a large bead is arranged on the lower end of the mounting rod near the counter base. The beneficial effects of the present invention are: the present invention adopts the combined design of small beads and large beads on the beads, so that during the experimental teaching, no matter the students in the front row or the students in the back row can clearly see the calculation displayed by the vertical counter. The number of beads is beneficial to experimental teaching; the present invention is provided with a small storage box and a writing board on the base of the counter, and a pen container is provided on one side of the counting baffle, and three new tools are added, which can greatly enhance the practicability of the vertical counter.

Description

technical field [0001] The invention belongs to the technical field of teaching tools, in particular to a vertical counter for experimental teaching. Background technique [0002] The evolution of mathematics can be regarded as the continuous development of abstraction, or the extension of the subject matter. Eastern and Western cultures also adopted different perspectives. European civilization developed geometry, while China developed arithmetic. The first concept to be abstracted was probably numbers (Chinese counting chips), and its recognition of the same thing between two apples and two oranges is a major breakthrough in human thought. In addition to knowing how to count physical objects, prehistoric humans also knew how to count abstract concepts such as time—days, seasons, and years. Arithmetic (addition, subtraction, multiplication and division) also arose naturally. [0003] In enlightenment education, children will be exposed to mathematics and learn simple alg...
