1, knowledge requirement: grasp the arithmetic of simple decimal;
2, prepare before playing; Pure decimal of red numeral on the upper right corner of numeral board, the black nonzero digit is represented a positive integer, such as red
Expression 0.2 is black
Expression 2, the also red expression 0.12 of regulation, black
Expression 12.Four-player is divided into two sides, and friend sits facing each other.
3, shuffle, take domino finish after, each one should just in time have 18 boards, then each one checks whether three symbol cards are arranged in the board in the own hand just, and wherein has again for existing No. ten No. one, otherwise must substitute mutually, lacking the symbol card person can select (or taking out) to get symbol card from the hand that has more symbol card, and then allows the other side extract the digital board of same quantity from the digital board of oneself.
4, substitute finish after, everyone 18 boards in the hand by add, subtract, add deduct, multiplication and division or the order that removes form six formulas.Such as carrying out combination and permutation like this with board
In
With
Be respectively the reverse side of one card, represent the multiplication sign and the division sign respectively.More than each formula be respectively 3+0.2,11-1,2-0.4,2 * 0.3,3 ÷ 0.5,12 * 0.5 must be noted that aliquot when repeatedly board is formed the division formula.
5, after each one group formula finished, four-player was revealed first addition formula simultaneously, and each one must accurately say its represented number, otherwise just can not score, then the size of four numbers relatively, the person that goes out the maximum number got 3 fens for first place, at this moment can be all close distributional as oneself of the board of putting forward.Second place got 2 fens, extracted out in the board that oneself is got to be used as distributionally in two opening and closing, and another is still bright on bidge table and must be by the branch of oneself.Third got 1 fen.Fourth is score not, and at this moment the board of just oneself being got is complete bright on bidge table.Be locked in a tie for first if any two people, then each got 3 fens, all the other two people are still 1 fen and zero.
After first leg finished, each one revealed second formula ...In each bout separating method and above said method are identical, in game process, everyone must note repeatedly putting respectively neatly oneself distributional with the useless board of mistake at any time.
6, carry out six bouts after, the first game of recreation just comes to an end, so just add up and write down the distributional number of each side, then each one just transfers their player whose turn comes next to together oneself distributional with the useless board of mistake, so just can begin to carry out second game and compete.In this way altogether must be by turns three times, just can make victory or defeat after having carried out four innings.
Win victory with big person for preceding two innings, separating method done introduction, last two sets are won victory with little person, promptly relatively during each number big or small, go out minimum number person and get 3 fens for first place in each bout.
First method-correspondence (one), (four people's playing methods)
1, knowledge requirement: can separate various simple equations,
2, prepare before playing; Carrying out this recreation needs with two secondary boards, before the recreation beginning, need organize from the A of deck by students ' actual situation earlier organize to J (I organize except) extract some groups out.(these boards are referred to as equation pieces) repeatedly is placed on bidge table central authorities, and board is towards last, and four people are divided into first and second liang of sides, and friend sits facing each other, and on behalf of absolute value, hundred can be not more than any one integer of 12 by board, also can represent unlike signs.
3, take domino; Deck is grabbed entirely to each staff in addition, and everyone must have three symbol cards in the hand, 15 digital boards (comprising hundred energy boards).
4, go out the X value; Correspond to example to beat the A group, the equation pieces that contains alphabetical A is repeatedly being put in bidge table central authorities.Both sides respectively have an opening lead to represent the X value of equation in the equation pieces.
Represent the available numerals of number with board, also available two digital boards by+,-, *, the formula of certain computing composition is represented number among the ÷, power.
If the two people branch of speed of having played a card when representing the X value with board, then slow person can not repeat the numeral that fast person goes out.
5, go out the Y value; It is complete that two people go out the X value, then they to the play a card Y value of expression and X value correspondence of family, be-X=1-Y to get the board of representing the X value earlier and be such as the equation of facing
Promptly 6, his should be 7 to the play a card number of expression of family.
6, win board; As in one bout, a side plays a card correctly, and then the board that can get two people in this bout is as this side's win board.
As the expression Y value of can't playing a card of the person of playing a card after among the side, then only getting the board of representing the X value win board earlier as this side.
As the board of having made mistakes, then this side can not win board in this bout, and at this moment two people just regain the board of getting separately in the hand.
7, change preface; After one bout finishes, just can rout up next equation pieces, in new bout, will change the order of playing a card, the expression X value person that promptly in last bout, plays a card, in new bout, the expression Y value of will playing a card.
8, by turns; After carrying out six bouts, the first game of recreation just comes to an end, so just add up and write down the win board number of each side.Then each one just transfers board remaining in win board of oneself and the hand to their the right one family together, so just can begin to carry out second game and compete.
After carrying out two innings, with the victory or defeat that how much decides of each side's total points.
The third method-work, (number of participant is not limit)
1, knowledge requirement; Grasp binomial multiplication.
2, go out multiplier; The person that at first do not take domino gets two binomial boards, require these two binomial long-pending in the coefficients of XY must be that absolute value is not more than 12 integer, otherwise just must reppear and in the end add up each one and win when board is counted and will deduct.
3 go out coefficient; After the binomial board was up to, all the other each one must the play a card coefficient of XY in they long-pending of expression was got the bridge queen and is closed earlier, each one all sprouts with when after bright again opening.
4, stay board; Go out the coefficient board correct and be the first place person of playing a card when one bout finishes, stay on the bidge table black numbers board be placed on oneself in face of.Correct but the slow person of speed of playing a card can stay a digital board of redness in front own.
5, work; The correct still whipper-in person of playing a card that plays a card must work once.So-called work is exactly correctly to read the binomial multiplied result.Such as facing two boards
Should read X
2Add that XY deducts 6Y.As read correctly, and can in face of own, stay a digital board of redness, as misread number, then in face of own, stay a symbol card.
It is wrong to play a card, and also must work, as read rightly can stay a symbol card in face of own, as misread then and can not stay board.
6, score; A black numbers board is remembered 3 fens, and the digital board of redness is remembered 2 fens, and a symbol card is remembered 1 fen.
