Description
Technical field
The utility model relates to educational aid, provides a kind of card form and to count teaching aid unit.
Background technology
Grasp knowledge and can be described as a kind of process being transitioned into the concept world from the phenomenon world, abstractness due to concept is grasped needs of knowledge and is paid suitable effort, and select the teaching tool of suitable imagery to contribute to contacting contacting of phenomenon and concept, thus reach the effect of getting half the result with twice the effort.For just starting the children contacting knowledge, this point is particularly important.
Therefore, in the fields such as language education, mathematics, science, start just to utilize card to help learning Vocabulary, concept etc. as aid in the past.But existing learning card is the simple form only utilizing the pros and cons of a card, is printed on things and is printed on word or numeral at reverse side in front, thus only pays close attention to the contact of pro and con, therefore, technique of expression and form are severely limited.For the middle additive operation that counts, if only record whole arithmetic operator formula on a card, then consider the diversity of arithmetic expression, in order to the number of cards understood needed for arithmetic operator rule is relatively many, and, because record whole arithmetic expression in each card, so for learner, the relation of addend and summand is seemingly decided, thus the dynamic change of addend and summand can not be embodied well, and then this dynamic change implication behind can not be grasped well.
Therefore needing exploitation, while more various concept can be comprised, can realizing by observing the teaching aid unit that newly counts making the function of students ' understanding rule.
To sum up, existing teaching aid is usually used alone, and lacks change; As need multiple effect be reached, often need to overlap teaching aid more.
Utility model content
The utility model proposes to solve the problem, its object is to provide a kind of card form to count teaching aid unit, its adopt one opaque, transparent two cards are as a unit, an arithmetic operator formula is separately recorded on described two cards, and utilize the geometric figure had in card to provide the answer of described arithmetic expression visually, thus by being suitable for different see-through cards to identical opaque card, make the dynamic change that student to find in described arithmetic expression between number, and then the mathematical law of this dynamic change behind and real implication can be grasped preferably.
For this reason, the utility model provides a kind of card form and to count teaching aid unit, it comprises card of the opaque end and transparent upper card that can be overlapped, card of the described end is identical with upper card shape and have count district and the geometric figure district that mutually distinguish respectively, indicate one first numeral in the district that counts of one of card of the described end or described upper card and in its corresponding geometric figure district, indicate the geometric figure corresponding with described first numeral, indicate at least one operational symbol in another the district that counts of card of the described end or described upper card with at least one second numeral indicates and described operational symbol and the corresponding geometric figure of described second numeral in its corresponding geometric figure district, when described upper card is overlapped on card of the described end, in the district that counts after overlap, at least mark has left equation, in geometric figure district after overlap, at least mark has the graphic result identified by geometric figure.
In one embodiment, indicate one first numeral in the district that counts of card of the described end and indicate in its corresponding geometric figure district and the corresponding geometric figure of described first numeral, described upper card the district that counts in indicate at least one operational symbol and at least one the second numeral and in its corresponding geometric figure district, indicate and described operational symbol and the described second digital corresponding geometric figure.
In another embodiment, indicate one first numeral in the district that counts of described upper card and indicate in its corresponding geometric figure district and the corresponding geometric figure of described first numeral, indicate at least one operational symbol and at least one the second numeral in the district that counts of card of the described end and in its corresponding geometric figure district, indicate and described operational symbol and the described second digital corresponding geometric figure.
The shape of upper card and end card is unrestricted, such as, can be rectangle or square, but also can be other shapes.
Further, the position of card of the described end and described upper card correspondence is provided with and aligns mark.
Further, the geometric figure in described geometric figure district is one-dimensional coordinate, the two-dimensional coordinate of band sign, one of the array or the scale map being with sign of band sign of band sign.
Further, described sign is arrow or semicircle.
Further, align described in and be designated rectangle, square, circle or one of semicircle.
Because the utility model provides a kind of card form and to count teaching aid unit, it adopts one opaque, one transparent two cards as a unit, an arithmetic operator formula is separately recorded in described two cards, and utilize the geometric figure had in card to provide the answer of described arithmetic expression visually, thus by being suitable for different see-through cards to identical opaque card, make the dynamic change that student to find in described arithmetic expression between number, and then this dynamic change mathematical law behind and real implication can be grasped preferably.By the combination of opaque conventional cards and transparent card, while generating new operational problem, utilize the geometric figure of image to furnish an answer intuitively, thus providing the happiness of observation to children, happy to realize the happiness being hidden in mathematical law principle behind happy.Because have employed the form of two cards as a unit, not only when number of cards is relatively few, the variation of arithmetic expression can be realized, and, if be suitable for different upper cards at identical end card, student then can be made to grasp the physical meaning of arithmetic expression unconsciously, thus contribute to student's understanding and grasp mathematical law.Because the mathematics language that to be the mankind general, so can be applicable to international market, is also applicable on the learning card of other kinds such as language, science.
