Come on and learn the advanced play of dice

When it comes to playing math games with dice, there must be N ways to read numbers, match points, compare sizes, play snake chess, and practice arithmetic. In short, dice can be used to replace all games involving numbers. I’ve shared some dice gameplay in math games on and off before. Today, I’d like to set the stage and share with you some advanced dice play — reasoning.

You might say, well, dice, everybody knows that, need some introduction? But to make sure the rest of the gameplay goes smoothly, LET me give you a quick introduction to dice.

 

Dice, or dice, are often called shǎ I zi in northern China. Traditional Chinese folk entertainment used for throwing objects, as early as the Warring States period, usually as table games props.

 

The most common type of die is a six-sided die, which is a square cube with one to six holes (or numbers) on each side, and the sum of the numbers on the opposite sides must be seven. Chinese dice are used to be painted red on one and four. Dice are random number generators that are easy to make and obtain. (Definition from Baidu Baike)

 

According to the definition of dice, we can make a die together with our children, as long as the sum of the numbers on the opposite sides is 7. (Self-made printing pictures can be obtained by directly replying “self-made dice” on the public account)

 

 

Two, the advanced play of dice

 

1

 

What’s the count on the opposite side?

 

This game is to consolidate the child’s grasp of the characteristics of the dice, that is, according to the existing dice, the number of the number of the opposite. The reason to put this game first, but also to let the child further familiar with the rules, so that the follow-up game better development.

 

 

As you can see, the number on the top is 3, and the number on the other side is 4. Other similar, can let the child face by face calculation.

 

2

 

What can’t be the opposite number?

 

This game is still on the premise of the law of dice, exercise children’s reverse thinking. According to the known dice number, the number on the side of the judgment is impossible to be a few, it is to let the child calculate the opposite number of known points, so as to determine the impossibility of the number of points on the side.

 

 

As you can see, the number of points on the top is 5, so the number of points on the opposite side is 2, so the number of points on the side cannot be 2.

Determine whether the self-made dice roll is correct?

 

I made a few dice, some in accordance with the law of dice roll, some do not meet, let the child according to the rules to judge whether my homemade dice roll is correct. If not, ask the child to give the correct answer and the reason.

 

 

As you can see, the first die is wrong, with a 2 on the top and no 5 on the side; The second die is wrong, there’s a 6 on the top, there’s no 1 on the side; The third die is correct. It fits the rule.

Calculate the sum of the other three sides of the die

 

Given the number of numbers on three sides of a die, have your child add up the number of numbers on the other three sides of the die. If the child does not have the ability to do arithmetic orally, he can do it by writing.

 

 

As shown in the figure, given that the number of points on the three sides is 2,3,6, the number of points on the opposite side is 5,4,1, so the sum of the three sides is 10.

 

5、Calculate the sum of unknown dice

 

Given the number of N dice (the dice can be rolled randomly, or the dice with a fixed number can be placed according to the child’s ability), let the child calculate the sum of the number of dice opposite the known number. If children have difficulty in calculating, they can start with two dice and gradually increase the difficulty.

 

Given that the number of the top three dice is divided into 2,4,6, the number of the opposite sides is 5,3,1, so the sum of the three sides is 9.
