# Initiating a child into the world of Mathematical Science

“How do I involve my son in challenging mathematics? He gets good marks in school tests but I think he is smarter than school curriculum.”

“My daughter is in 4th grade. What competitions in mathematics and science can she participate? How do I help her to perform well in those competitions?”

“I have a 6 years old kid. He hates math. How do I change that?”

We often get queries and requests like these from parents around the world. Literally. In fact the first one came from Oregon, United States, second one from Cochin, India and last one from Singapore.

# Red Flags

## 1. Stay away from exact arithmetic

Fifth grade is the first time a student is exposed to algebra and geometry simultaneously (in most schools). Note that the arithmetic of exact computation (example: what is the exact value of 31 + 57?) is fundamentally different from arithmetic of approximation or geometric reasoning. They are processed by different parts of the brain (that is neurologically they are distinct).

Unfortunately the school arithmetic (or olympiads organized by some private organizations) are mostly focused on exact computation. This approach is counterproductive for the development of young mind. It is prudent to keep the student away from these harmful practices.

An alternative practice is to expose the student to “approximation” (example: is the sum of 31+243  larger than 300?)

## 2. Stay close to vernacular literature

Imagination plays a big role in mathematical science. Vernacular literature can be the greatest source of childhood imagination. Greater focus on a  second language (like English in India or Spanish in U.S.) may be an impediment for the child’s mental development. Let your child read a lot of story books in vernacular literature.

## 3. Be aware of dyscalculia

Dyscalculia is a mental state (like dyslexia) where the child has difficulty in processing numbers especially to associate symbols with magnitude. For example most of us when look at the symbols 5 and 500, associate distinct spatial magnitudes to each of them (5 is small, 500 is large). If your son finds it difficult to do so, he or she may perform terribly in school arithmetic test.

Please note that it might be counter productive to force him to learn tables and do well in those tests (in fact learning tables is a bad thing to do under any circumstance). It may drive him away from mathematical science altogether. If he has dyscalculia he may do well in visualization (say geometry) instead of exact arithmetic. Some branches of mathematics are free of ‘magnitude’ in a sense (some forms of geometry are examples). Let your son try those things if he fairs badly in computational mathematics.

It is not at all uncommon to have dyacalculia (remember jt is less of a disease and more of mental state so do not panic). About 2 to 3% of any population has this state of mind in all countries. Unfortunately most schools are ill equipped to handle such situations.

## 4. Not all mathematicians favor olympiads

Though math olympiads can be an excellent exposure to non standard problems, not all mathematicians favor them.

“Many of the winners in mathematical Olympiads that I know have, unfortunately, not been very successful as mathematicians when they grew up unless they continued to study like hell…. there are people who, though slow-witted at Olympiads, are good at solving problems that may take years to solve, and at inventing new theorems or even new theories.” – Dimitry Leites

So it is prudent to use competitions and olympiads as motivators and focus on “learning the subject for it’s sake”.

## 5. Abacus, Vedic mathematics

Computation techniques like Abacus or Vedic mathematics are not only useless from a mathematician’s point of view, they may have negative pact on a child’s brain. Mathematics has very little to do with computation. Most of mathematics is pure logical reasoning. Do not waste your child’s time and mental ability for the sake of some swift multiplication.

Some argue that apart from computation these techniques have another purpose- improving concentration and focus. Whether or not these claims are true, it is better to use other methods (like meditation, team sports, chess) for improving concentration and focus.

# Contests, resources and methods

## 1. Create a dry lab at home (and if possible a wet lab)

A dry lab with simple equipments for physics, chemistry and astronomy experiments is useful. Books like Quest Vol. 1 and 2 are sources of simple experiments. You may also buy a simple telescope and a microscope. City dwellers may visit rural countryside in week ends for clearer skies and less distraction.

Astronomy can be an great motivator for mathematics and physics. Consider the Orion constellation. This is the most prominent constellation in the night sky. It has one red star located at the crest. Investigations like “why is it red” or “why the Orion is the brightest” or “how far the stars are from each other” are great motivators for discussions in physics, astronomy and mathematics.

Instruments

• A moderately powered telescope
• Calipers, thermometers, simple volt-, ohm- and ammeters, potentiometers, diodes, transistors, simple optical devices
• Double-beam oscilloscope, counter, ratemeter, signal and function generators
• Analog-to-digital converter connected to a computer, amplifier, integrator, differentiator, power supply.

Students in 13 to 18 year age group from all around the world may participate in this contest. A fifth grader may begin preparing for it at home using the lab. Intel science fair is another similar contest. These links are useful:

## 3. American Math Contest 8 and Math Counts

These two contests are available for American students but the problems presented here are useful for all students of 5th and 6th grade.

## 4. Use of computers

Computers are a necessary evil. You may use softwares like mathematica for illustrating math concepts with visuals. But it is generally more useful to allow the visuals to form in the mind first. In fact locus questions are most critical in the formation of mathematical reasoning in the young mind. But note that if the brain of the child lacks proficiency in visualization one should not force them to do so. A child may be capable of handling discrete mathematics (say counting, combinatorics) better than visuals (geometry). Great Romaninan mathematician Louise Posa is one example. Computers may aid you to identify this trait to. Elemmentary computer programming especially in C may help in honing this aptitude in a child.

Exposure to internet and television is generally counterproductive due to lack of restrain and similar factors. Especially replacing indoor and outdoor sports by video games has been statiscally proven to be counterproductive to a child’s physical and mental development.

A great book for locus problems (geometry in motion) – Vasiliyev’s Lines and Curve (it is available in our library).

## 5.Books

Last but not the least, books play a very important role in the academic development of a child. Here is a great list of books. Some of them are out of print but available in our library. Not all of them can be used at the age of 10 but gradual exposure to these resouces is priceless.

# Conclusion

Please note that though a teacher is indispensable for learning, a great deal can be achieved by self-help with sympathetic and flexible facilitation from parents. It is unwise to occupy a child’s free time by coaching and tutorials at an early age. Use the above mentioned methods with care and we hope you will be able to help your child to do what he or she is most comfortable.
