Get rid of fear of mathematics and
score 100%
score 100%
In a class of 40
boys, on testing, we found that about 80% of them score low marks in
Mathematics.

When we tried to find
the reasons for this low marks we found the following reasons:
the reasons for this low marks we found the following reasons:
1. The kid did not understand the basics.
2. Lack of practice
3. Fear of asking the teacher when the child
has not understood the basics

4. Lack of reasoning
5. Lack of the meaning of different words used
in framing the questions.

6. An unwarranted fear that maths is tough
7. Last but not the least is criticizing the
child when it does the problems and branding them as a duffer and dull student.

8. Dyscalculia is the fear of maths, as others
keep saying it is tough and the mind accepts it as a difficult subject.

9. Not knowing the Formula is another reason
for not being able to do.

10. Basics, tables and conversion of units not
being performed by the kid, leads to wrong answers.

Let us see how we can
overcome these problems.
overcome these problems.
In order to do fast
calculation, recalling certain facts and figures is necessary.
For example knowing the tables would be of great help. (hence commit it to
memory 2, 20 up to 20 times)

For example knowing the tables would be of great help. (hence commit it to
memory 2, 20 up to 20 times)
When we say what is
16 times 16, most of the class v children would not know. This can be avoided
if the tables are committed to memory

How does it help?
What is (42x
42)?
42)?
This is clearly 16 x
16 = 256
16 = 256
If the child does not
know this it will start as follows:-
know this it will start as follows:-
( 42 = 4 x 4 = 16x 4 = 64 x 4 = 256) You can see it
has to take yet another step to arrive at the answer.

This not only is a
waste of time and sometimes a wrong calculation is multiplying adds to agony.)

Example 2: Express
82575 millilitres in terms of kilolitres, litres, deciliters and centiliters.
82575 millilitres in terms of kilolitres, litres, deciliters and centiliters.
One must know the
relations between each term. Is between centiliters and milliliters and litres.

For word problems
Break down the problem as
What is asked?
What is asked?
What are the facts/ data given?
Is there a requirement to convert the units?
What is the correct formula to be used
Work out step by step
Verify the answer by rechecking the steps.
Use alternative method to arrive at the answer
Practice each and every sum given in the exercise of your school book ( maths)
You will succeed.
All the best
