Abstract
The utility model relates to an abcus mental arithmetic teaching magnetic teaching apparatus, which is composed of calculating plates and calculating beads, wherein, the calculating plates is provided with a horizontal bar which separates the calculating plates into an upper part and a lower part; the back surfaces of the calculating beads are embedded with magnets used for absorbing the calculating beads on the calculating plates. The calculating beads can optionally change and move on the calculating plates, making different digitals combined. The utility model has the advantage of high operation and is suitable for that children learn and understand abacus code and abacus roles. The utility model is a bridge for children learning the abacus.
Description
The utility model relates to a kind of teaching aid, particularly a kind of teaching aid that is used for the mental arithmetic of rechoning by the abacus formula.
Abacus is the ancient and computational tool of science of China, and abacus teaching also is the compulsory course in China's mathematical education.For the children more than 8 years old, understand and accept " five liters of decimal system " notion and and then the study abacus rhymes be to be relatively easy to.But these notions just seem abstract for the children in 5-7 year and indigestion.Therefore, design the children's study of a kind of 5-7 of help year and the teaching aid understanding the pithy formula of abacus and calculate reason just seems very necessary.
The purpose of this utility model provides a kind of children of being suitable for and learns abacus teaching and rechoning by the abacus formula mental arithmetic teaching magnetic teaching aid.
Magnetic teaching aid of the present utility model is formed by calculating plate and bead, and calculation plate wherein is the square ferrous metal plate of a block length, or the plastic plate that tundish is wrapped with iron plate, has a horizontal bar will calculate plate on the calculation plate and is divided into two parts up and down.Bead can be any geometric configuratioies such as circle, rhombus, triangle, is made into multiple color simultaneously, is inlaid with magnet in the behind of bead, bead can be adsorbed on to calculate on the plate.
During use, if bead by below the horizontal bar of calculating plate, bead is representative " 1 " just, calculates plate horizontal bar top if be placed on, bead is representative " 5 " just.A plurality of beads can be combined into the Any Digit computing of imparting knowledge to students.
Magnetic teaching aid bead of the present utility model can arbitrarily move variation, piece together and form many different numbers, workable, allow children's study abacus rhymes on the basis of understanding manage with calculating, the psychological characteristics that meets 5-7 year children, be that 5-7 year children learn the bridge of rechoning by the abacus, play very big effect improving 5-7 year children abacus learning.
And the utility model magnetic teaching aid visual pattern, bright in luster, can improve the interest of children's study, reach the effect of getting twice the result with half the effort.
Fig. 1 is the structural representation of the utility model magnetic teaching aid;
Fig. 2 is the structural representation at the bead back side.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, rechoning by the abacus formula mental arithmetic teaching magnetic teaching aid is formed by calculating plate (1) and bead (2), calculating plate (1) is a rectangular plastic flitch that is wrapped with iron plate at tundish, on calculation plate (1), there is a horizontal bar (3) will calculate plate (1) and is divided into two parts up and down, a round dot is arranged on the horizontal bar (3), can be used as radix point and use.Bead (2) back side is inlaid with magnet (4), can be adsorbed on to calculate on the plate (1), and bead (2) makes red diamond shape.
The utility model both can be used as children's abacus teaching teaching aid, also can be used as children's intelligence and inspired toy.
Claims (4)
1, a kind of rechoning by the abacus formula mental arithmetic teaching magnetic teaching aid is formed by calculating plate (1) and bead (2), and it is characterized in that: described calculation plate (1) is the ferrous metal plate, is inlaid with magnet (4) in the behind of bead (2).
2, magnetic teaching aid according to claim 1 is characterized in that: calculating on the plate (1) has a horizontal bar (3), will calculate plate (1) and be divided into two parts up and down.
