Abstract
The present invention is mathematics Excercising board for pupil, can be used for addition subtraction multiplication and division and practises, and view formulation calculates exercise, distance, engineering and other calculating exercise, right-hand man's button, energy luminous and sounding type, and technique is simple, low cost.Classroom instruction can be used for, improve learning interest.
Description
Technical field: such as add for pupil's mathematical knowledge, subtract, take advantage of, remove；And view formulation calculates, distance, engineering problem is relevant to be calculated, energy
Luminous and sounding type, technique is simple, and low cost improves students ' interest of study.
Background technology: existing can be used for mathematics classroom teaching, electronic product vacancy at a low price affects mathematics classroom teaching quality.
Summary of the invention: mathematics Excercising board divides upper and lower two parts: bottom is divided into two numbers to be added, and be multiplied formula, and each formula divides left and right two numbers, top
It is divided into the relevant total of following formula, forms such quantitative relation: left+right=on, right+left=on, upper-left=right, upper-right=left；Left × right=on,
Right × left=on, upper ÷ is right=left, and upper ÷ is left=right.About the most each formula, two numbers and the most corresponding total make contactor, connect
Come, connect with the mains, display lamp, buzzer, will be luminous, sounding.
Accompanying drawing illustrates: Fig. 1 is practice board plate face.Fig. 2 is layout.Fig. 3 is plus-minus exercise, and this version is to add 2 figures.Fig. 4 is multiplication and division exercises,
This version is to take advantage of 2 figures.Fig. 5 is that rectangular perimeter calculates exercise figure.Fig. 6 is rectangular area calculating figure.Fig. 7 distance formula calculates exercise figure.Figure
8 is that engineering formula calculates exercise figure.Certainly can also practise a lot of formula to calculate.Scheme medium and small bird's eye eyeball dress display lamp.
Detailed description of the invention: each formula divides left number, right number, upper number, all connects contactor in 3 numbers, the most each formula has 3 switches,
And be together in series, pin numeral above with a finger during exercise, another finger arbitrarily pins following left number or right number, and circuit ON, bird
Eyes load onto display lamp, external buzzer, so that it may luminous and sounding type.Change different paster and just can practise different content.
Claims (2)
- The feature of mathematics Excercising board for pupil the most of the present invention is that upper part and lower part are divided in plate face, and lower part arranges 10 formulas in order, Each formula divides left and right two numbers, represents and is added or is multiplied, above have the calculating total of they correspondences in square frame, form such quantitative relation: left Number+right number=upper number, right number+left religion=upper number, upper number-left number=right number, upper number-right number=left number, left number × right number=upper number, right number × left number= Upper number, the upper left number of several ÷=right number, the upper right number of several ÷=left number, pin the number in square frame above during exercise with a finger, another finger with Time pin any one number in left and right of following corresponding formula, so that it may luminous and sounding type, push the wrong unglazed the most noiseless.
- 2. each formula is made up of 3 numbers, and each numeral is equipped with a contactor, and is together in series, and thus forms 1 requirement Quantitative relation and practice effect.
