The shoulder of mobile beads two of transverse axis, form the gesture in corner；Extension is symmetrical, is exactly that a mobile beads of the second transverse axis first are slid into alignment the
The fixation beads 5 of one transverse axis, another mobile beads of the second transverse axis with the fixation beads 13 of the 4th transverse axis for symmetry axis, equally to walk
Number dorsal glides are to symmetrical nodes, it was observed that fixation beads 8,8 of the symmetrical nodes institute to the first transverse axis as 13-5 number of results.
If asking several decomposition, the 4th transverse axis that the mobile beads alignment of the 3rd transverse axis is decomposed several first can be fixed into beads, then
The left and right sides that two mobile beads of the second transverse axis are slid into above the 3rd transverse axis mobile beads shoulder along axle, form the gesture in corner.
Then backwards to separating, progressively both sides extend to the left and right.Such as 13 are decomposed, the 3rd transverse axis mobile beads are first directed at the transverse axis of the earth's axis the 4th
Fixation beads 13, then the mobile beads of the second transverse axis are run to the shoulder of the 3rd transverse axis mobile beads two, form the gesture in corner, then are carried on the back
To phase from both sides are synchronously extended to the left and right, and 6 can be so obtained on the first transverse axis and is symmetrically detained with 7,5 and 8,4 and 9 three groups
Node, that is, obtain tri- groups of breakdowns of 6^7,5^8,4^9, for gather ten methods selection use.
As further improvement of the utility model, the fixation beads of first transverse axis is spherical fixed beads, described
The fixation beads of 4th transverse axis is square fixed beads.
As further improvement of the utility model, the mobile beads of second transverse axis are spherical movable pearl, the described 3rd
The mobile beads of transverse axis are square mobile beads.
As further improvement of the utility model, the rectangular frame, montant are integrated making, and 4 parallel transverse axis are only
It is vertical to make.
Relative to prior art, the utility model has following beneficial effect：
1st, the utility model is the initiating learning calculator designed according to underground map, add operation " to pearl, corner,
Diffusion is symmetrical ", the mode of subtraction " symmetrical to pearl, corner, diffusion ", convenient for children memory, contribute to children's intuitivism apprehension
Operation law.
2nd, the utility model is in order to easily identify, the first transverse axis fixes beads, the second transverse axis mobile beads can use sky blue
Sign, the 4th transverse axis fixes beads, the 3rd transverse axis mobile beads can be indicated with khaki.Color mark number, children can quickly look for
Quasi- beads.
3rd, use different shape to make beads to distinguish to show.First transverse axis fixes beads, the second transverse axis mobile beads are all circle
Pearl；4th transverse axis fixes beads, the 3rd transverse axis mobile beads are all Fang Zhu.Pearl is divided into two groups of circular upper part and square lower part, upper circle is used to add, under
Side is used to subtract, and can deepen the understanding that subtraction is the inverse operation of addition.
