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


In upcoming posts we will discuss about Associative property of multiplication and How to Sketch Transformations? Visit our website for information on biology syllabus for class 10 ICSE
