Equations are one of the types of tasks in a math lesson. Someone, faced with them, decides everything quickly and easily. Someone is still not clear what and how to find. If the child is having difficulties - help him! Pay attention to this already in elementary school. Systematic exercises will help solve this problem. What should you pay attention to?
It is necessary
- - a pen;
- - notebook;
- - a textbook of mathematics.
Instructions
Step 1
Have your child write down the equation and read it. When reading the unknowns contained in the equation, in the elementary grades, the names of the letters of the Latin alphabet are used.
Step 2
Ask the question, "What do you want to find in this equation?" The child must say what the unknown in this entry means.
5 + x = 7 - you need to find the unknown term.
5 * x = 10 - you need to find an unknown factor.
x-3 = 7 - you need to find the unknown diminished.
10's = 3 - you need to find the unknown subtracted.
x: 3 = 5 - you need to find the unknown dividend.
15: x = 3 - you need to find the unknown divisor.
Step 3
Ask your child to think of the rule for finding the unknown in the equation. For example, in order to find an unknown term, you need to subtract the known term from the sum.
Another example: in order to find an unknown divisor, you need to divide the dividend by the quotient.
These rules are indicators of the relationship between action components. They study them in math lessons. Check your child regularly for the strength of their assimilation!
Step 4
If the child finds it difficult to formulate the rule, together with him find the necessary formulation in the reference materials at the end of the mathematics textbook. The child must read the rule and memorize it.
Step 5
Plug the equation into the rule formulation with your child.
When solving the equation x-3 = 7, the child's complete answer should sound like this: "In the equation x-3 = 7, we do not know the diminished. In order to find the unknown diminished, you need to add the difference to the subtracted. To the subtracted 3 I add the difference 7, I get 10. So x = 10 ".
Step 6
Check the recording of the solution to the equation:
x-3 = 7;
x = 3 + 7;
x = 10.
Step 7
Then you need to check the correctness of the solution to the equation. The child must substitute the found number into the original equation. Next, you need to calculate how much you get on the left and right sides of the equation and compare these numbers. If the numbers are equal, the equation is solved correctly. If not, then you need to look for an error in reasoning or calculations.
10-3=7;
7=7.
The equation is solved correctly.
