Multiplication facts and tables

Hello students, in mathematics there are lots of operations which we have to perform so that we can reach on some results. The operations are addition, subtraction, division and multiplication (how to do 3 digit multiplication). Simply the facts mean something  actually happened and the in multiplication facts we find missing term and final results when we already have all terms. For example : -
2 * 10 = ?
Solution will be 20. In this we can get result by adding 2 at ten times and by adding 10 at two times. Both are same.
5 * ? = 20
Missing term will be 4.
Multiplication table for the initial 5 numbers are : -

1 times 1 = 1, 2 times 1 = 2, 3 times 1 = 3, 4 times 1 = 4, 5 times 1 = 5, 6 times 1 = 6
2 times 1 = 2, 2 times 2 = 4, 3 times 2 = 6, 4 times 2 = 8, 5 times 2 = 10, 6 times 2 = 12
3 times 1 = 3, 3 times 2 = 6, 3 times 3 = 9, 4 times 3 = 12, 5 times 3 = 15, 6 times 3 = 18
4 times 1 = 4, 4 times 2 = 8, 3 times 4 = 12, 4 times 4 = 16, 5 times 4 = 20, 6 times 4 = 24
5 times 1 = 5, 5 times 2 = 10, 3 times 5 = 15, 4 times 5 = 20, 5 times 5 = 25, 6 times 5 = 30

Like the above method we can obtained next terms and we can also get more multiplication tables for the other numbers. I hope the information about the multiplication facts and tables will make sense to 4th grade math students

Multiplication problems

This unit is designed for Grade IV and here in help in math session we are going to learn about Multiplication problems. We know that multiplication word means to add repeatedly and to increase in the fixed quantity. Here we are dealing with the problems of multiplication, we need to first learn that what all are the problems of multiplication, how to do double digit multiplication and  how to recognize such problems.
Some times we come across real life problems, in which we are given the cost of one article and we need to find the cost of more than one article. For instance if we say that the cost of 1 cod drink is $2, now if a child wants to buy 2 cold drinks, he needs $2 + $ 2 =$4 . Further if he requires three cold drinks, he will spend  $2 + $ 2 + $2 = $ 6. Thus what we observe is that every time the number of cold drinks is increasing , we are adding $2 to the previous total, or we can say that the cost of unit article is added the number of times the object is required. It can also be done more easily if there are n number of objects and the cost of 1 article is multiplied by n. for more on this subject visit this
This is easier and simple method of getting the solution for problems of multiplication.
Example: If 1 sack of rice cost 25$, then find the cost of 5 sacks of cement.
Sol: We know that the cost of 1 sack of cement = $ 25
So, to find the cost of 5 sacks of cement, we need to  multiply the cost of the unit  sack by the number of the sacks required.
So we get = $25 * 5 = 125 $
In this way all such real life problems can be solved using multiplication.
