1. First, observe the multiplication sign and the equal sign in the box, and make sure that the number to be filled is a multiplication formula. For example, if there is "3×" in the box, then we need to fill in a number and an equal sign to make this multiplication formula hold.
2. Then, observe the numbers and operation symbols in the box and try to find some rules. For example, if there is "2+4=" in the box, then we can find that the sum of these two numbers is equal to 6. Similarly, if there is "5-2=" in the box, then we can find that the difference between these two numbers is equal to 3. Try to fill in the numbers in the box according to the rules found.
3. For example, if there is "3x" in the box, and we know that 3 times of a certain number is equal to 6, then we can try to fill this number into 2 (because 3x = 6). Similarly, if there is "5-2=" in the box, we know that 5 MINUS a number equals 3, then we can try to fill this number into 2 (because 5-2=3).
4. If the number filled in does not meet the conditions in the box, you can try other possible numbers. For example, if the number is 2, but we find that 3×2=6 does not meet the conditions in the box, then we can try to fill in other numbers until we find the right number.
Characteristics of the third grade
1, the learning ability is gradually improved: Grade three students have mastered the basic reading and writing ability and can complete simple reading and writing tasks independently. Their mathematical ability is also constantly improving, and they can perform simple operations of addition, subtraction, multiplication and division. Longer concentration time: Compared with Grade One and Grade Two, Grade Three students have longer concentration time.
2. Enhance social skills: Junior three students begin to pay more attention to their relationship with others, and can get along better with their classmates and establish friendship. At the same time, they also began to learn to express their thoughts and feelings, and enhanced their communication skills. The initial formation of autonomous learning ability: Junior three students began to gradually form the consciousness and ability of autonomous learning, and can think positively.
3. Increased interest in knowledge: With the growth of age and the deepening of study, the interest of junior three students in all kinds of knowledge is gradually increasing, and they are willing to take the initiative to understand and explore new fields.
