The equations - one of types of tasks at a mathematics lesson. Someone, having faced them, solves everything easily and quickly. To someone it is not clear as how to find. If the child experiences difficulties - help him! Pay it attention already at elementary school. Systematic classes will help to solve this problem. What to pay attention to?
It is required to you
- - handle;
- - notebook;
- - textbook by mathematics.
Instruction
1. Ask the child to write down the equation and to read it. When reading the unknown who are contained in the equation in initial classes names of letters of the Latin alphabet are used.
2. Ask a question: ""That it is required to find in this equation?"" The Child has to tell that the unknown in this record.5+ designates x =7 - it is necessary to find unknown composed. 5*kh =10 - it is necessary to find an unknown multiplier.x-3=7 - it is necessary to find unknown reduced. the 10th =3 - need to be found unknown deductible. x: 3=5 - it is necessary to find unknown divisible.15: x =3 - it is necessary to find an unknown divider.
3. Ask the child to remember the rule necessary for search of the unknown about which it is in the equation. For example, to find unknown composed, it is necessary to subtract from the sum the known composed. Other example: to find an unknown divider, it is necessary to divide a dividend into private. These rules are communication indicators between components of actions. Study them at mathematics lessons. Regularly check durability of their assimilation at the child!
4. If the child is at a loss with formulation of the rule, together with it find the necessary formulation in reference materials at the end of the textbook by mathematics. The child has to read the rule and learn it.
5. Substitute together with the child data from the equation in the wording of the rule. At the solution of the equation x-3=7, the full answer of the child has to sound so: ""In the equation x-3=7 to us it is not known reduced. To find unknown reduced, it is necessary to deductible to add a difference. To deductible 3 I add a difference 7, I receive 10. Also =10 means"".
6. Check record of the solution of the equation: x-3=7; x =3+7; x =10.
7. Then it is necessary to execute check of correctness of the solution of the equation. The child has to substitute the found number in the initial equation. Further it is necessary to count how many it will turn out in the left and right members of equation and to compare these numbers. If numbers are equal - the equation is solved truly. If is not present, then it is necessary to look for a mistake in reasonings or calculations.10-3=7;7=7. The equation is solved truly.
