The Top (6) Six Reasons Why Mental Math is Important & Useful for Kids
1.
Mental
math methouds are
usually faster than technology, if you have an efficient strategy. For
example, you can calculate that 25% of
80 is 20, in your head, faster than someone can pull out a calculator (or
cell phone) and take 0.25 × 80. The
key is knowing that 25% is one fourth, which
means to divide by four—and one can divide by four by dividing by two twice.
2.
Mental math is
useful in everyday life and technology
(and paper) may not be available or appropriate. Examples: Working in a concession stand calculate the total
for a popcorn, Coke, and candy bar; dividing the N1800 pizza bill between
four people; find sale price of clothing that is 30% off.
3.
Mental math is useful
to check or estimate an answer obtained from a calculator (or other technology
or someone else or from a paper and pencil calculation). Did the order at the
fast food restaurant get rung up correctly? Is the answer to the homework
problem reasonable? Did you get the proper change at the concession stand?
4.
Being able
to do (at least some) math mentally leads to fluency and confidence. Make the comparison to someone who is fluent in a
foreign language. If someone is fluent in French, then they can carry on a
conversation without stopping to look up words in a dictionary or taking long
pauses to compose a sentence, but can combine various words and structures in
the normal flow of conversation. Similarly, when solving a math problem, it
flows better if you can precede using your head rather than dancing fingers on a
keypad or thumbing through a book. Fluency happens in the mind. No matter what
the activity, confidence helps one be successful.

It will be on the test. Tests will contain no calculator portions. Students will
be expected to use mental math and paper-and-pencil methods. …and the Number

Mental
math methods help you understand mathematics.
This makes homework and the learning new concepts easier. Understanding occurs
in the mind. Increased understanding leads to less frustration, success, and
higher grades.
