It is very important to know the multiplication table for any child, it is learned at elementary school, and it becomes base for further studying arithmetics. On a question how to learn the multiplication table in 5 minutes, there is no answer, in fact, as it is almost impossible to learn it from scratch for such short time. But if you want to know how quickly to learn the multiplication table with the child, some councils will be useful.
Instruction
1. Begin with multiplication by 1 and 10vsegda it is necessary to begin studying the table with multiplication by 1 and 10. The child quickly will understand that multiplication by 1 first multiplier does not change. And if some number is multiplied by 10, to it 0 is just attributed.
2. Multiplication on 2razobratsya as with the child to learn the multiplication table on 2, is simple too. The school student will quickly understand that at multiplication on 2 it is necessary just to put the multiplied number with it. So, 5х2 = 5+5 = 10, and 8х2 = 8+8 = 16. Multiplication on 4 and 8 is similarly remembered.
3. Multiplication on 5 Multiplication table on 5 is taught quicker if the child understands at once that in the answer the number terminating on 0 or on 5 will always turn out. At multiplication of five by even number, the last figure will always be responsible 0, and at multiplication by odd – 5.
4. You somnozhiteleyobjyasnit the rule of change of places to the child that from change of places of factors the work will not change. That is if he increases 5 by 2, the same will turn out, as at multiplication 2 on 5. Knowledge of this simple rule considerably will reduce training time. For example, if the school student needs to decide how many will be 2х8 instead of putting number 2 eight times, he will put two times number 8 and will receive here that: 2х8 = 8х2 = 8+8 = 16.
5. Key diagonal of a tablitsykvadrata of numbers 2х2, 3х3 and so on to 10х10 is a key diagonal of the multiplication table. If the child remembers how many he will be 2x2, 3x3 and so on, the question as it is easy to learn the multiplication table, for you will become simpler. So, knowing that 8х8 = 64, the pupil will quickly consider how many there will be 8х9. The following turns out: 8х9 = 8х8 + 8 = 72.
6. Multiplication on 9A how quickly to learn the multiplication table on 9? Having remembered multiplication of numbers by 10, the child will be able easily to learn and multiplication by 9. So that to solve how many will be 7х9, will be to increase 7 by 10 enough, and then to take away 7. It turns out: 7х9 = 7х10 – 7 = 63.
