Abstract
The utility model provides a novel mathematics exercise-book. The top surface of a calculating card is provided with calculating titles, and the lower parts of the titles are answers. An opaque sleeve with a display window is arranged on a calculating board, and the sleeve is externally provided with thin films which can be heaved up. The calculating card is inserted into the sleeve, and the calculating titles can be shown from the display window, while the answers are hidden by the sleeve. The utility model has the characteristics that the use is convenient, the interest of calculation of children is enhanced, etc. The utility model is particularly suitable for the children of pre-school ages and the children who begin to study to exercise mathematical problems.
Description
The utility model relates to a kind of children's schooling apparatus, the novel mathematics practice book that particularly a kind of children use.
At present, preschool child of China or first at primary school children remain when the calculation exercise and seeing that bookish exercise question calculates on exercise-books.The dullness calculation of this custom can only be finished exercise question, but can not obtain answer at once, therefore child is produced and be weary of sense.In addition, after exercise question does wrong, can only lean on the teacher comment operation, or just find during parental counseling.When correcting mistakes, fray exercise-book, the exercise-book that when exercise-book damages or uses up, also need renew through regular meeting.
The purpose of this utility model provide a kind of have exercise question and answer, can own verification to the novel mathematics practice book of mistake, it is not only easy to use, and can also strengthen child's calculation interest.
The purpose of this utility model is achieved in that it comprises calculating plate, computer card, sleeve, it is characterized in that having above the computer card calculating exercise question, exercise question below to be answer, calculate the opaque sleeve that has display window on the plate, sleeve is equipped with the film that can start outward, computer card inserts in the sleeve, calculating exercise question can appear from display window, and answer is hidden by sleeve.
Principle of work: the computer card that will have exercise question and answer inserts from the sleeve socket that has two display windows, exercise question can show from the display window of sleeve, at this moment available pen calculates on the calculating plate, because of calculating one deck manifolding plastic film is arranged above the plate, therefore solve a problem and calculate on the manifolding plastic film, computer card then moves up, mathematical problem moves on to first display window, answer can show from second display window, can contrast the calculation topic and the answer of calculating on the plate this moment, as have the stroke of can taking of mistake fall, and perhaps starts plastic film, the calculation topic just can disappear, and can recomputate on the manifolding plastic film.After finishing, topic on the computer card can extract interchangeable computer card when changing exercise question out from the spigot of sleeve as needs.
The utility model has the advantages that: novel structure, technology is simple, and is easy to use, can alleviate some burdens that the head of a family and teacher teach the student.Also book can be saved,, the interest that child does topic can be strengthened with doing with looking for answer.
Do the embodiment explanation below in conjunction with accompanying drawing.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
By Fig. 1,2 as can be known, being in the same place with 4 compression moulding of sleeve top in sleeve bottom 2, can synthesize a sleeve 6 and sleeve 7, the opening part of sleeve 6 is on sleeve, the opening of sleeve 7 is in the side of sleeve, and computer card 3 is put into sleeve 6 and moved up and down, and computer card 3 is put into sleeve 7 move left and right.Calculating plate 5 sticks on the centre position of sleeve display window neutral gear, can calculate plate at it and show the arithmetic problem order, and mobile computing card 3 can find answer, and verification is to mistake.Fall as wrong available stroke, or start film 1, film 1 stick on calculate plate 5 above, start film 1, the exercise question of calculating can disappear.Sleeve 6 and sleeve 7 can fold along the dotted line place, promptly constitute a complete exercise book.
