How to teach a child to solve equations
Equations - one of the types of jobs in the math class. Someone faced with them is everything easily and quickly. To some it is not clear how and what to find. If a child is having trouble - help it! Pay attention to this as early as elementary school. Systematic studies to help solve this problem. On that same note?
You will need:
- a pen; - notebook; - Math textbook.
Instruction how to teach the child to solve the equation
Ask your child to write the equation and read it. When reading the unknowns contained in the equation in primary school used the names of letters of the Latin alphabet.
Ask a question: "What you want to find in this equation?" The child has to say, which means unknown in this record. 5 + x = 7 - you need to find an unknown term. 5 * x = 10 - it is necessary to find the unknown factor. x 3 = 7 - you need to find the unknown is reduced. 10 x = 3 - need to find unknown subtracted. x 3 = 5 - you need to find an unknown dividend. 15: x = 3 - you need to find an unknown divider.
Ask your child to remember a rule, you need to search for the unknown, referred to in the equation. For example, to find an unknown term, it is necessary to deduct from the amount of the well-known term. Another example: in order to find the unknown divisor, the dividend should be divided into private. These rules are indicators of communication between the components of action. Learn the lessons of mathematics. Regularly check the child the strength of their assimilation!
If the child is more difficult with the formulation of rules with it find the correct wording in the reference materials at the end of the textbook of mathematics. The child should read the rule, and memorize it.
Put together with the child data from the equation in the formulation of the rules. In solving the equation x 3 = 7, a full child's answer should be: "In the equation x 3 = 7, we do not know is reduced. In order to find the unknown is reduced, you need to add the subtrahend difference. 3 adds to the deductible difference of 7, I get 10. So x = 10".
Check recording solutions of the equation: x 3 = 7; x + 7 = 3; x = 10.
Then you need to perform validation of solutions of the equation. The child should substitute the number found in the original equation. Next, you need to count how many will turn to 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 a mistake in reasoning or calculations. 7 = 10.3; 7 = 7. The equation solved correctly.
