Tools needed: drawing paper, brush.

1. Draw four red lanterns on the left side of the handwritten newspaper, in which the score heaven is written.

Draw a sunflower, a cube, a book and a small house on the right side of the handwritten newspaper.

3. Dye the petals of sunflower yellow, draw horizontal lines inside and write down the story of music score.

Draw small mushrooms, butterflies and flowers around the book. The book contains content with relatively high scores.

5. Paint blue on the right side of the cube and draw a few small blue stars on the cube to introduce the meaning of the score.

6. The small house below is painted green, and it says calculation, mainly fractional calculation.

Extended knowledge

I. Scores

Fraction originally refers to a part of the whole, or more generally, to any equal number of parts. It is controversial whether a false fraction in which the ratio of integer A to integer B is a multiple of b is a fraction.

Fraction indicates the fraction of one number to another, or the ratio of one event to all events. Divide the unit "1" into several parts on average, and the number representing such a part or parts is called a fraction. The numerator is above and the denominator is below. [When the denominator is 100, it can be written as a percentage, such as 1%.

Second, history.

The earliest fraction was the reciprocal of an integer: an ancient symbol representing one-half, one-third, one-quarter and so on. Egyptians used the Egyptian score of 1000 BC. About 4000 years ago, Egyptians separated with slightly different scores. They use the least common multiple and unit fraction.

Their method gives the same answer as the modern method. Egyptians also have different representatives of Akhmim sawdust and the second generation of mathematical papyrus.

The Greeks used unit fractions and (post) continuous fractions. The Greek philosopher Pythagoras (about 530 BC) found that two square roots cannot be expressed as part of an integer. Usually this may be wrong, because hippasus of Metapontum is said to have been executed to reveal this fact.

Among 150 Indians in India, Jain mathematicians wrote "Sthananga Sutra", which includes number theory, arithmetic operation and operation. The modern music score known as bhinnarasi seems to have originated from India in Ayabata (about 500 AD), and then [need to quote] Brahma Gupta (about 628 AD) and Bascara (about 1 150 AD).

Their works form fractions by putting the numerator (Sanskrit: amsa) on the denominator (cheda), but there is no stripe between them. In Sanskrit literature, fractions are always expressed as addition and subtraction of integers. Integer is written in one line, and its score is written in the next line of two lines. What if the score is in a small circle? 0was or cross? +was tag, which is subtracted from the integer; If such a sign does not appear, it is understood as adding.
