Description

Primary school mathematics five, six-year system second grade teaching aid box

The utility model relates to the teaching demonstration apparatus that a kind of primary school mathematics education demonstration equipment, particularly five-year system primary school or six-year system primary school second grade are used.

At present, in the sophomoric mathematical education of five-year system or six-year system primary school, for helping children to understand, usually all to adopt some such as learning aids such as counting rod, triangle and circular piece, owing to, do not require parents of student oneself to do usually, increased burden to the head of a family with the supporting teaching aid box of teaching material, and the kind of manufacturing is also limited because of the limitation of conditions and extremely, and quality also is difficult for guaranteeing.

The purpose of this utility model is exactly in order to address the above problem, provide that a kind of kind is complete, quality good, with the organic one by one primary school mathematics that cooperates five of teaching material full content, six-year system second grade teaching aid box.

Technical solution of the present utility model:

A kind of primary school mathematics five, six-year system second grade teaching aid box box body, a plurality of partitioned cavity are arranged in its box body, be used to place multiple learning aid, it is characterized in that box body inner bottom surface one side is provided with a row and the jack that the counting rod outside diameter matches, and correspondingly indicates the figure place indication in box body appearance side.

A kind of primary school mathematics five, six-year system second grade teaching aid box learning aid, it is placed in the box body in each corresponding partitioned cavity, it is characterized in that learning aid shows that by square sheets, rectangular pieces, equilateral triangle sheet, circular piece, parallelogram sheet, counting rod, count slice, multipurpose ruler, semi-automatic clock, activity hornwork forms.

The utility model is a foundation with nine-year-system obligation syllabus, the operation item in the teaching material that closely cooperates, and its learning aid kind is complete, and quality is good, adapts to children's physiology, psychological characteristics fully.The utility model is simple in structure, cost is low, long service life, under teacher ' s guidance, children by to the observation of each parts of the utility model, piece together operations such as pendulum, displacement, form one by one operating structure intuitively, through starting, move eye, beating one's brains, open one's mouth in the concrete image that causes in person and experience, understand notion happily, analyze quantitative relation, form clearly cognitive structure and preliminary sky and ask idea, improve teaching quality comprehensively.

As Fig. 1-4, can be provided with 6-10 cavity 2 in the box body 1, be used to place various learning aids, lid 3 inside surfaces are marked with multiplication formula table 4, box body 1 inner bottom surface one side is provided with a socket hole 5, is used for pegging graft with the counting rod, correspondingly indicates figure place indication 6 in box body 1 appearance side.

As Fig. 5-19, in the learning aid parts, indicate numeral 0,1 ... respectively 2 of 9 square sheets 7, count 20, rabbit pattern square sheets 8 is 4, square sheets 9 is 10, and pentagram circular piece 10 has 10,11 20 of flower shape circular piece, have sign of operation+,-, *, ÷ and relational symbol＞,＜,=, respectively 2 of the circular piece 12 of (), rectangular pieces 13 is 1, and apple pattern triangular piece 14 has 10, and pears pattern triangular piece 15 has 10, counting rod 16 has 20, count slice 24 has 6, and parallelogram sheet 17 is a slice, 18 1 of multipurpose rulers, have the geometric configuration slotted eye on it, activity shows that hornwork 19 is 2, and it is made up of two flat bars, and each flat bar one end is provided with a projection 20, its other end has the aperture 21 that matches with projection 20 external diameters, the projection 20 of a flat bar and the aperture 21 of another flat bar connect, and promptly can be used for demonstrating various angles, and semi-automatic clock 22 has 1.Wherein there are circular piece 10,11 centers of pentagram and design to have through hole 23, are used to be set in counting rod 16.

Counting rod, count slice mainly help the student to understand the meaning of multiplication and division method, the counting rod can cooperate the formation counter of pegging graft with the jack of box body inner bottom part one side simultaneously, pearl is deceived replacement with the circle that has center pit, correspondingly corresponding each jack position indicates individual, ten, hundred, thousand, ten thousand equal-order digits indication in box body appearance side, the former students ' understanding digit hundred, thousand, ten thousand that can allow, know the decimal system relation between adjacent two digits, grasp ten thousand with interior number bit sequence, help student's reading and write number.How much sheets of different shape mainly help the student to understand the meaning of multiplication and division method and two kinds of point-scores of division, help the student to understand simple two steps computing application topic.When semi-automatic clock mainly supplies students ' understanding chronomere, branch.Slotted eye on the multipurpose ruler mainly helps student's album to close figure, helps to understand the notion of " doubly ", and can be used as the ruler use.Activity shows that hornwork mainly helps the size at various angles of students ' understanding and angle.Various symbols are for students ' understanding relational symbol and sign of operation and utilization symbol and sum formula.Rectangle, square, parallelogram sheet are mainly tentatively grasped rectangle, foursquare feature, visual understanding parallelogram for the student.
