Mathematics is such a nice thing that all of us use it in every step of our life whether we learn it at school or not. While walking, jumping, cooking, playing, driving, riding a bi-cycle or doing any activity, we are using mental calculations all the time, may be unciously. Anyone who has sound knowledge of math can do well in any other subjects.
In our place
in India mostly, metric system is used except for length measurement where inches and feet are most commonly used. To covert inches to centimeter, to get a rough estimate, we multiply it 2 and add half of it to the result. For example, 5 inches equals (5 X 2) + 2.5 = 12.5 cm (approx.).
There are so many good games available in the internet to learn mathematics for kids. Below is a link to have fun with math : http://www.dep.anl.gov/aattack.htm.
Barry's Response - That is a decent approximation for this
metric conversion, Jahnabi. Thank you.
Originally the conversion factor was 2.54000508 cm to a inch, but at some point the inch was redefined so that it is now exactly 2.54 cm.
