24÷4= We can decompose 24 into 4×6, then divide 4 by 4 to get 1, and write 6 on the next line to get the answer 6. Similarly, we can split 36 into 6×6, then divide 6 by 6 to get 1, and write 6 on the next line to get the answer 6.
48÷8= Divide 48 by 8×6, divide 8 by 8 to get 1, and write 6 on the next line to get the answer 6. 56÷7= We can multiply 7 by 8 to get 56, then divide 7 by 7 to get 1, and write 8 on the next line to get the answer 8. In the division operation, we need to correspond the dividend with the divisor, and then divide.
If the dividend is not divisible by the dividend, there will be a remainder. In the above example, we simplified the calculation process and decomposed the dividend into products that are easy to calculate. At the same time, the answer can be found quickly by applying the rules of the provider. Books such as A Brief History of Mathematics and The Beauty of Mathematics are all good choices.
Multi-operation: After mastering the basic operation, you can try some complicated operations, such as mixed operation and simple operation. These operations can help students improve their calculation ability and problem-solving ability. Fill-in games: In addition to filling in box questions, there are many fill-in games that can help students exercise their mathematical thinking and calculation ability.
Such as Sudoku, digital games, etc. Mathematical problems in life: Many problems in life can be transformed into mathematical problems, such as time, distance and speed. These questions can help students to apply mathematics to real life and improve their mathematics application ability.
Math contest: Participating in math contest can help students improve their math level and broaden their math horizons. Mathematics competitions usually include multiple-choice questions, fill-in-the-blank questions, proof questions and so on. , can exercise students' mathematical thinking and problem-solving ability. Mathematical stories: Reading mathematical stories can help students understand the history and development of mathematics and broaden their horizons.
