Abstract
The utility model discloses a multiplication table teaching aid, and the multiplication table teaching aid structurally comprises a magnetic plate and character blocks, wherein the magnetic plate is step-shaped and is divided into 45 rectangles that are equal in size; the height of the magnetic plate is progressively decreased from one end to the other end; the highest end of the magnetic plate is formed in a way of overlapping 9 rectangles; the length of the magnetic plate is progressively decreased from the bottom end to the top end; the lowermost bottom end of the magnetic plate is formed in a way of arranging 9 rectangles in parallel; and magnets are arranged on the back surfaces of the character blocks. The multiplication table teaching aid disclosed by the utility model can be used for explaining the multiplication table, and a teacher does not need to write on a blackboard, so that the multiplication table teaching aid is relatively vivid, and improves the classroom efficiency.
Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of multiplication pithy formula teaching aid.
Background technology
Multiplication pithy formula is very important for the student, it also is the basis of learning mathematics, therefore must skillfully grasp multiplication pithy formula, because multiplication pithy formula is uninteresting, when beginning to contact, the student is difficult to grasp, teacher is saying class hour also do not have corresponding teaching aid, needs a large amount of writings on the blackboard, lose time and effect bad.
The utility model content
The purpose of this utility model is to provide a kind of multiplication pithy formula teaching aid, and this teaching aid can be saved the time of teacher's writing on the blackboard, improves classroom efficiency.
The technical scheme in the invention for solving the technical problem is: a kind of multiplication pithy formula teaching aid, comprise magnetic sheet and character block, and described magnetic sheet is stepped, magnetic sheet is divided into 45 equal-sized rectangles; The height of magnetic sheet from one end to the other side successively decreases successively, and an end of magnetic sheet height maximum is nine rectangle stacks; The length of magnetic sheet is successively decreased to the top successively from the bottom, and the magnetic sheet lowermost end is that nine rectangles arrange side by side; The back side of described character block is provided with magnet.
The beneficial effects of the utility model are: demonstrate multiplication pithy formula by character block assembled arrangement on magnetic sheet, need not teacher and write at blackboard, saved the time, and more lively, improve classroom efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 magnetic sheet, 2 character blocks.
Embodiment
As shown in Figure 1.A kind of multiplication pithy formula teaching aid comprises magnetic sheet 1 and character block 2, and described magnetic sheet 1 is stepped, and magnetic sheet 1 is divided into 45 equal-sized rectangles; The height of magnetic sheet 1 from one end to the other side successively decreases successively, and the highly maximum end of magnetic sheet 1 is nine rectangle stacks; The length of magnetic sheet 1 is successively decreased to the top successively from the bottom, and magnetic sheet 1 lowermost end is that nine rectangles arrange side by side; The back side of described character block 2 is provided with magnet.
The front of character block 2 is provided with numeral and mathematic sign, and the magnet on magnetic sheet 1 and the character block 2 can attract each other.During use, character block 2 is arranged to form multiplication pithy formula at magnetic sheet 1, when 45 rectangles of magnetic sheet 1 are filled up, just in time forms a complete set of multiplication pithy formula, need not teacher and write at blackboard, saved the time, and more lively, improve classroom efficiency.
