1, draw mathematical elements, such as numbers, triangles, rulers, etc. , you can draw it in. For the handwritten newspaper of the subject, the border can be in the style of blackboard or book, which is a great layout.
2. If you want to draw some simple mathematical tabloids, you can also draw a geometric border, which is also great. The content of "interesting mathematical stories" is provided by Xin Wei's manuscript. How many peaches did Bajie eat? Bajie went to Huaguoshan to find Wukong, but the Great Sage was not at home.
The little monkeys warmly treated Bajie and picked 100 of the most delicious mountain peaches. Bajie said happily, let's eat together! How to eat? Counting ***30 monkeys, Bajie found a branch and drew it on the ground, and listed the formula, 100 ÷ 30 = 3. Eight, eight rings, top three. Generously speaking, you can eat three pecans each. Look, the rest 1 I ate it! The little monkeys were very grateful to Bajie. They thanked him one by one, and then each took his share.
When Wukong came back, the little monkeys told Wukong how generous Bajie was today and why he only ate a pecan. Wukong saw Pig's arrangement and shouted, What a fool! After eating too many pecans, he even shut up. I'll find him! Haha, do you know how many peaches Bajie ate?
arithmetic
The addition rules involving fractions and negative numbers are designed. Addition has several important properties. It is interchangeable, which means that the order is not important, it is interrelated, which means that when more than two numbers are added, the order in which the addition is performed is not important. Repeatedly adding 1 is the same as counting; Adding 0 will not change the result. Addition also follows related operations such as subtraction and multiplication.
Addition is one of the simplest digital tasks. The most basic addition: 1+ 1 five-month-old babies and even other animal species can be counted. In primary education, students are taught to calculate the superposition of decimal numbers, starting with one digit, and gradually solving the more difficult number calculation.
