What is 2nd grade math finding x?
The math of finding x in class 2 is known as a form of math based on the rule of finding the unknown components of addition, subtraction, multiplication, and division operations.
Example: Find x, know:
X + 7 = 15
=> x = 15 – 7 = 8
=> x = 8
Some difficulties when children learn 2nd grade math find x
For the math form of finding x in grade 2, students often face some difficulties leading to not understanding the lesson, making calculation errors such as:

Do not understand calculations: In math, finding x is a type of exercise that appears all 4 operations of addition, subtraction, multiplication, and division. If you do not know how to calculate these calculations, finding x will be very easy to go wrong.

Children’s thinking ability is not high: Math to find x is a form of thinking math, requiring children to find the rules of the problem to find the correct x. Therefore, if they cannot reason, it will be very difficult to solve the exercises.

Did not read the topic carefully: In math, just putting the wrong sign of the calculation will also lead to the wrong result, so many children do not read the question carefully because changing the sign will not change the math rules to find x.
Types of maths to find x in class 2 and solution methods
In the 2nd grade math program, children will be familiar with the following types of maths to find x from basic to advanced:
2nd grade math form find basic x
Solution method: We will rely on the rule to find the unknown components of the corresponding calculations as follows:
 Addition: x + b = c or a + x = c. The rule to find x would be: Term = sum – term
 Subtraction: x – b = c or a – x = c. The rule to find x would be: Subtracted number = difference + subtraction or subtraction = subtracted number – difference
 Multiplication: xxb = c or axx = c. The rule to find x will be: Factor = product : factor
 Division: x : b = c or a : x = c. The rule to find x would be: divisor = quotient x divisor or divisor = divisor : quotient.
For example:
a) X + 12 = 36 – 20
b) X – 24 = 58 – 11
c) X : 4 = 48 – 47
e) X x 3 = 12 + 3
Advanced math grade 2 find x
With this form of math for finding x in class 2, the problem will have many combinations to find x. Solution, you will also proceed to move the x side to the other side, and at the same time will change the sign and perform the corresponding calculation.
In addition, with advanced math, there are forms of grade 2 math exercises with solutions. Ask them to read carefully to analyze the data of the existing problem, ask them to solve the problem correctly.

Help children master the knowledge of addition, subtraction, multiplication, and division
To learn 2nd grade math to find x exactly requires the child to correctly calculate the calculations first. Usually, 2nd graders will usually only learn calculations within 100, where most of it is addition, subtraction, multiplication, and division knowledge.
Therefore, parents need to ensure that their children can calculate addition, subtraction, multiplication and division of the multiplication table quickly and accurately to be able to solve the problem of finding x correctly. To do this, parents should regularly check their child’s knowledge, or ask math questions to see how their child’s calculation ability is to reinforce knowledge in time.
Practice with your baby often
Once your child has mastered the theory, create conditions for him to practice more often. Practice can come from doing homework with your child, experiencing activities on BINH THANH Math High School, organizing related games, etc.
It is the regular practice of children that will help them remember knowledge better, as well as have interest and develop thinking ability when learning math more effectively.
Refer to many math exercises to find x in grade 2 online
Instead of just letting children learn and solve exercises on textbooks assigned by teachers, parents should consult with their children and learn more related exercises. With the strong development of technology today, there is a lot of knowledge on the internet for parents and children to refer, learn and practice.
Try your hand at advanced math
To promote children’s ability to learn math, parents should try to let their children conquer advanced forms of 2nd grade math to see how far their child’s ability is instead of just doing basic math. At the same time, with this method, parents will know how the child’s receptive ability is, thereby giving the best way to teach to reinforce knowledge for children.
