A bedtime math story

Bedtime Math and Tinybop offer educational apps.
When our son was young, my wife and I would read to him every night before he went to bed. We loved the time spent with him. This delightful ritual continued till he learnt to read himself.
A study by children’s book publisher Scholastic, released earlier this year, says that you should continue reading to them even after they have learnt to read. They like it.
When we read to him, we chose a story because we thought he would like it, because it was fun. Often he would choose the story that he wanted read out to him. None of the stories had a deliberate educational purpose: There were no dates to remember, lessons to learn or numbers to add and subtract.
Now, a study by the University of Chicago in the US, published two weeks ago in the journal Science, says reading your children bedtime stories that have an element of math improves their performance in the subject in school.
So if you have young children and are anxious about their mathematical skills, this could be what you are looking for. Even if you yourself have a bit of math anxiety and are not comfortable with numbers.
For their study, the Chicago university researchers used an app called Bedtime Math that posts a daily math-related bedtime story to its users. Three years ago, Laura Bilodeau Overdeck, who holds a bachelor’s in astrophysics from the US’ Princeton University and a master’s in business administration from the Wharton School of the University of Pennsylvania, set up the non-profit Bedtime Math (www.bedtimemath.org) “to make math fun for kids”.
The app packs the stories with nice sound effects. You can download the free app, get your daily story, and read it out to your children at night. The app is meant for parents and children to use together.
To give you an idea of the stories, here’s a recent one called “Letting The Cat Out Of The Bag”.
“What does it mean when people ‘let the cat out of the bag’? It means the truth came out, usually about something someone did wrong. They say it comes from farmers selling pigs hundreds of years ago. Pigs were worth a lot of money, but cats weren’t. So when handing over a live piglet in a thick bag, sometimes a sneaky farmer would slip a cat in there instead. But then he had to hope the cat didn’t pop out and ruin everything before the farmer ran away with the money.”
For each story there are three levels of questions: for “wee ones”, “little kids” and “big kids”. So the pig-and-cat question for “wee ones” is: “If the cat and pig fall asleep at 2pm and nap for 3 hours, will they be up in time for dinner at 6pm?” And this one for big kids: “A domestic pig can weigh more than 700 pounds! If this one weighs just 400 pounds and the cat weighs 10 pounds, how many cats would have to pile up to match the pig?”
To someone not afraid of numbers, these are fairly simple questions. The Chicago university study shows “a marked increase in math achievement among children whose families used Bedtime Math” app. It says the math performance showed an improvement even in cases where parents read to the children their favourite bedtime stories six days of the week, switching to a story from Bedtime Math on just one day.
And while we are talking about educational apps for children, do check out this website called Tinybop (www.tinybop.com), which makes amazingly elegant apps that have won several awards. I have never seen a more beautiful learning app than The Human Body and The Earth created by them. They have released just five apps, and each one of them is a piece of art.
In its Digital Toys series, Tinybop has an app called The Everything Machine (Rs.190) which lets a child use the tools built into your phone—such as the battery, camera and speaker—and create some very imaginative apps. It uses a visual programming language that enables the user to drag and link the various tools so as to make the phone perform some interesting tasks. I downloaded it purely for its design.

Algebra is easy with these fast math tricks for solving problems involving binomial, trinomial and polynomial equations.



Sin cos tan as well as a liitle pythagorus....




Fractions, fractions, fractions. These are essential knowledge in maths.



Vedic Maths

Vedic Mathematics is the name given to the ancient system of Indian Mathematics which was rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krsna Tirthaji (1884-1960). According to his research all of mathematics is based on sixteen Sutras, or word-formulae. For example, 'Vertically and Crosswise` is one of these Sutras. These formulae describe the way the mind naturally works and are therefore a great help in directing the student to the appropriate method of solution.

Perhaps the most striking feature of the Vedic system is its coherence. Instead of a hotch-potch of unrelated techniques the whole system is beautifully interrelated and unified: the general multiplication method, for example, is easily reversed to allow one-line divisions and the simple squaring method can be reversed to give one-line square roots. And these are all easily understood. This unifying quality is very satisfying, it makes mathematics easy and enjoyable and encourages innovation.

In the Vedic system 'difficult' problems or huge sums can often be solved immediately by the Vedic method. These striking and beautiful methods are just a part of a complete system of mathematics which is far more systematic than the modern 'system'. Vedic Mathematics manifests the coherent and unified structure of mathematics and the methods are complementary, direct and easy.

The simplicity of Vedic Mathematics means that calculations can be carried out mentally (though the methods can also be written down). There are many advantages in using a flexible, mental system. Pupils can invent their own methods, they are not limited to the one 'correct' method. This leads to more creative, interested and intelligent pupils.

Interest in the Vedic system is growing in education where mathematics teachers are looking for something better and finding the Vedic system is the answer. Research is being carried out in many areas including the effects of learning Vedic Maths on children; developing new, powerful but easy applications of the Vedic Sutras in geometry, calculus, computing etc.

But the real beauty and effectiveness of Vedic Mathematics cannot be fully appreciated without actually practising the system. One can then see that it is perhaps the most refined and efficient mathematical system possible.


For Kids 

Vedic math is a quick method of doing multiplication, division, addition and subtraction in maths. Become a math genius!



For Adults

The following videos give great insight about Vedic Math's origin, introduction and different areas of application.





One day on YouTube, Alex Bellos saw a video of an amazing mathematical "trick". He wanted to know more about this 'Vedic Mathematics', so he got on a plane to India. This is a lecture about his journey that touched on mathematics, mysticism, Indian history, nationalism and culture.

Learn Times Tables From 6 to 10 Using Fingers

To learn the times tables use your hands as well as your head! Multiplication had never been so easy using this easy trick - including some of the six, seven, eight, nine and ten times table.
This particular video enables learners, who have had difficulties with 'tables', to use low technology (namely their own hands)to work out the more difficult "Times Tables"!
