In online tutoring for free for Grade III, we will be learning about the Multiplication tables and Multiplication facts
Let us first learn what multiplication is. Multiplication means repeated addition. Multiplication is represented by a sign “ * “. Now we see that when we write 3 * 5, it means 5 is added 3 times and it can be expressed as 5 + 5 + 5 = 15
Also we have 3 * 5 = 15. To make the process of multiplication easier, the multiplication tables are formed, which are learned orally by the tiny tots in smaller grades
We express the table of any number n as
N * 1 = n
N * 2 = 2 times n
N * 3 = 3 times n
N * 4 = 4 times n
And it … proceeds till
N * 10 = 10 times n
Now following the above rule we write a table of 3 as:
3 * 1 = 3
3 * 2 = 6
3 * 3 = 9
3 * 4 = 12
3 * 5 = 15
3 * 6 = 18
3 * 7 = 21
3 * 8 = 24
3 * 9 = 27
3 * 10 = 30
Now we look at the multiplication fact: (get more detail here)
We must remember that if we write 3 * 4 or we write 4 * 3 it will produce the same result.
Thus for any division fact , there exist 2 multiplication facts. Let us try it with some example:
If we are given a division fact 30 / 5 = 6 what are the two multiplication facts for it:
The above division expression can be written as :
5 * 6 = 30 , which means that 6 added 5 times gives 30.
or we will write 6 * 5 = 30, which means 5 added 6 times gives 30.
In upcoming posts we will discuss about Inverse relationship of multiplication and division and Equivalent fractions. Visit our website for information on ICSE syllabus for class 3 maths
