Abstract

The utility model relates to a modular teaching aid; a block for children's quick study of mathematics suggested by the utility model is jointly composed of positive hexahedron computing building blocks and symbol building blocks. The computing building block is composed of different quantitative dots and corresponding digitals; the symbol building block is jointly composed of large words +,-, *, /, = and > and small words +,-, *, /, = and >. The block for children's quick study of mathematics can visually demonstrate the digital concepts and the operational relations required to be mastered by infants, and can carry out various mathematical operations of true objects and digitals simultaneously appearing.

Description

Blocks for children's quick study of mathematics

The utility model is a kind of mathematics accelerated learning building blocks for child's use.Belong to the brick pattern teaching aid.

At present, the building blocks of selling on the market, the child can only be used for showing the buildings of various image etc., does not see a kind of special teaching aid formula building blocks for child's learning mathematics knowledge as yet.

The purpose of this utility model is the teaching aid formula building blocks that a kind of special use is provided to the child, and these building blocks can vivid demonstration go out mathematical concept, the theorem of the required grasp of child and carry out computing, makes their grasp mathematical knowledge fast in playing.

The utility model is achieved in that building block is made up of positive hexahedron, indicates 0,1,2,3,4,5,6,7,8,9,10 in a side of positive hexahedron respectively, is ∴ ∷ in other upper end, five sides of positive hexahedron

Or with corresponding other pattern of its quantity, correspondence indicates 1 at the middle part, lower end, 2,3,4,5,6,7,8,9,10, arabic numeral, between point and arabic numeral, separate with a horizontal line, or on positive hexahedron building block top indicate+,-, *, ÷,=,＞centre separates with horizontal line, the lower end corresponding mark of small character+,-, *, ÷,=,＞sign of operation, during use, the child can learn the numeral of recognizing the below by top round dot or pattern, also can directly learn the some subnumber or the pattern number of top by the numeral of below, make the child set up thing and getting in touch of counting, these building blocks also can add for the child, subtract, take advantage of, the computing that removes, the upper end is a visual illustration during computing, the lower end is the numeral calculation, and is very visual in image.

The utility model is simple in structure, makes easily, can adopt wood, plastics to make.

Now in conjunction with the accompanying drawings the utility model is further described

Fig. 1, be the stereographic map of the utility model calculation building block.

Fig. 2, be the plane outspread drawing of the utility model calculation building block.

Fig. 3, be the stereographic map of the utility model symbol building block.

Fig. 4, be the plane outspread drawing of the utility model symbol building block.

Embodiment:

A kind of infant mathematics accelerated learning building blocks with the utility model feature are made up of 25 positive hexahedron building blocks, wherein 1～No. 20 building block is the calculation building block, as Fig. 1, Fig. 2, shown in, a side at the calculation building block, indicate 1,2,3,4,5,6,7,8,9,10 arabic numeral respectively, indicate ∴ ∷ in other five side upper ends of calculation building block

The lower end indicates and the corresponding arabic numeral 1,2,3,4,5,6,7,8,9,10 of round dot number, the point and arabic numeral between separate with horizontal line.21～No. 25 building blocks be the symbol building block as Fig. 3, Fig. 4, shown in, between symbol, separate with horizontal line, have respectively in the upper end, five sides of symbol building block big word+,-, *, ÷ ,=, the middle part, lower end indicate small character+,-*, ÷=.Separate with horizontal line between big word symbol and the small character symbol.In another side of symbol building block wherein No. 21.22 building blocks indicate No. 0.23 building block of arabic numeral for＞number, No. 24.25 the building blocks upper end be a blank, the lower end is small character arabic numeral 0, is horizontal line above small character 0.

25 positive hexahedron building blocks have been formed the special teaching aid formula building blocks for child's learning mathematics knowledge of a cover jointly, and these building blocks can be demonstrated out the mathematical concept that the preschool child grasps, the maths demonstration teaching aid that principle also can be used as a kind of child's special use.

Claims (2)

1, a kind of infant mathematics accelerated learning building blocks of forming by positive hexahedron building blocks, it is characterized in that calculating round dot that varying number is arranged on the building block or pattern and with round dot quantity or the corresponding arabic numeral of number of patterns; Have on the symbol building block big word+,-, *, ÷ ,=＞and small character+,-, *, ÷ ,=＞symbol.

2, building blocks according to claim 1, it is characterized in that between round dot or pattern and arabic numeral or big word+-* ÷=＞and small character+-* ÷=＞between can indicate horizontal line.
