Models for multiplication

Hello students, In ICSE syllabus for class 3 maths we multiply various numbers which are also repeated in 4th grade math. To multiply the numbers we follow some models so that we can easily multiply. Models are the easy representation of anything. Now I am going to show you some models for multiplication.
Skip counting: - In this model like we have numbers 1 2 3 4 5 6 7 8 9 10 11 12 and so on and we want 2's table than we can skip one number and we can take next number and apply this process as many time, then we will get 2 4 6 8 10 12 and so on...
Repeated Addition: - In this we can add repeated numbers, by doing this we will also get the same result. For example in this row 7 8 4 6 3 7 4 3 4 7 6 3 4 6 3, 7 is appearing at three times. If we add the 7 + 7 + 7 than we get 21 and if we multiply the 7 from 3 times ( because 7 is appearing in that row at 3 times ) 7 * 3 = 21. So both will produce same result.
Sets : - In this model like we have 3 sets and every set contain the 7 elements than the multiplication result will be 3 * 7 = 21.
Combination : - In this model, we make a combination of similar elements and then multiply them.
Arrays : - In this we multiply the numbers row and column wise.
Scale model : - Generally used in image type objects. More understand by graphically.
Models simplifies the process of multiplication.

I hope the information about the multiplication models will make sense to Grade III students.

Multiplication problems

Hi Friends! in this online math tutor free session we will discuss about multiplication problems. Problems of multiplication are defined as the process of adding same number n times means when a number is added multiple times then this large process is short by using the multiplication. There are some multiplication problems and properties of multiplication that are useful for grade III students that are as follows:
As if there are addition of six for five times then (6 + 6 + 6 + 6 + 6) is equal to (6 * 5) that is equal to 30 and we easily understand that is a short method then the addition.
If there are problem related with finding the number of things in the equal groups means if there are four group of students and each have 9 students then total students are find by the help of multiplication as total number of students = 4 * 9 = 36 students.
If there are problems related to the arrays that means if there are number of rows 5 and number of columns in each row are 5 then find the number of total columns in the table.
This is also one type of multiplication problem and it is solved as:
Total number of columns = no of rows * no of columns in single row
Total number of columns = 5 * 5 = 25.
There are also some problems that related with the comparison means if the one object's value is n times to the other then this is also solved by the multiplication as understand by an example if Ana have
9 $ and Jenny have 4 times more than Ana then how many rupees Jenny have ?
So the total money of Jenny = 4 * money Of Ana
= 4 * 9
= 36 $
So by the multiplication we can easily find such types of question in very short period of time.
