Cuboid volume calculation exploration teaching aid for primary school mathematics teaching

Abstract

The invention relates to the technical field of teaching aids, and particularly discloses a cuboid volume calculation exploration teaching aid for primary school mathematics teaching, which comprisesa lower box body, an upper box cover is nested above the lower box body, a stepped groove is formed in the lower box body, a magnetic attraction block is placed in the stepped groove, and a graduatedscale is engraved at the edge of the stepped groove.w An oily pen is placed on the stepped surface of the stepped groove. The beneficial effects are that: 1, students carry out study by themselves onthe teaching aid through the prompt of the operation sheet, thereby achieving the purposes of finding rules, mastering the application of an arithmetic theory and a learner, solving problems, and changing the passive learning and hard memorization dilemma of students; 2, the problems of no calculation, inaccurate calculation and no love of calculation in the calculation process of the volume of the cuboid are solved; 3, the progress is fast, students can quickly master the calculation formula of the cuboid volume, and the learning efficiency is improved; and 4, teaching is carried out throughactual operation, and the enthusiasm degree of students to mathematics is improved.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to teaching aids for calculating and exploring the volume of cuboids used in elementary school mathematics teaching. Background technique [0002] Teaching aids are models, real objects, specimens, instruments, charts, slides, etc. used to explain something, including teaching equipment, teaching instruments, training equipment, educational equipment, experimental equipment, teaching specimens, teaching models, etc. [0003] The research results of pedagogical psychology show that in the initial stage of knowledge formation, students must rely on their senses, first transform the observation and contact of specific things into perceptual knowledge that has nothing to do with specific things, and then transform perceptual knowledge into abstract, generalized rational understanding. As a tool for teachers to assist teaching, teaching aids have an irreplaceable role by other mea...

AI Technical Summary

Problems solved by technology

[0005] The calculation of the volume of a cuboid is what students must learn in primary school. The existing teaching method is that the teacher asks the students to memorize the calculation formula by rote, and then applies the calculation formula to calculate, which fails to allow students to participate in independent activities and interesting games. Fully feel and understand why the volume of a cuboid is calculated according to the formula, which leads to low enthusiasm and low learning efficiency for students in active learning
