How Much is a Billion?

Everyone is talking about spending billions of dollars to save the economy but how much is a billion?

We all know how to count to 100. We count by 10's, 5's and 2's but when the numbers get higher it becomes more and more difficult to comprehend just how much that number means.

Here you will find books, games, activities and ideas for exploring large numbers. Hundreds, thousands, millions and even a billion. The numbers keep adding up. How much is a billion?

After reading the story, One Grain of Rice, take out a large page from a calendar. Tell the children that together you are going to glue grains of rice onto the days of the calendar to represent the rice that Rami received from the Raja.

At first it seems like an easy job but soon the numbers get just too high to count. This is a project that will never be completed but this realization is what it is all about.

One Grain Of Rice: A Mathematical Folktale

It's the story of Rani, a clever girl who outsmarts a very selfish raja and saves her village. When offered a reward for a good deed, she asks only for one grain of rice, doubled each day for 30 days. Remember your math? That's lots of rice: enough to feed a village for a good long time--and to teach a greedy raja a lesson.

Measuring a Billion Grains of Rice

Now it's time to start talking about estimating. Somewhere between the 7th and the 10th days it will become too tedious to count individual grains. This is why people estimate or use measuring devices to determine amounts.

Count how many grains of rice fit in a teaspoon. How many teaspoons fit in a tablespoon? How many in a cup?

Going through the exercise of actually counting the rice to discover that you can measure the number of rice fairly accurately by spoonful or cupful is an important life skill and one that won't be forgotten when children are given the time to do the actual counting and measuring.

The MegaPenny Project 

Using Pennies to Understand Large Numbers

The MegaPenny Project aims to help people understand these huge numbers by showing on a computer screen drawings of the quantities involved. It may very well be the best way to deal with the largest numbers but as much as possible it is important to experience these numbers with your hands.

Pile up as many pennies as you can. Ask to visit a vault at a bank to see more pennies and see if it is still possible to pick up a bag of pennies. Ask how much it weighs and how many pennies are in the bag.

How Much Is a Million? 

Maybe it's easier to understand a million.

Now that we have experimented with gluing a billion grains of rice and thought about various ways of counting to a billion, maybe a million will seem a more reasonable amount to contemplate.

How Much Is a Million? 20th Anniversary Edition (Reading Rainbow Book)

Children are often intrigued by or confused about (sometimes both) very large numbers. Here Schwartz uses concepts that are simple to help readers conceptualize astronomical numbers like a million, billion, and trillion.

Examples: If a million children climbed on each other's shoulders, they would reach higher into the sky than airplanes can fly; if a billion of them made a human tower, it would reach past the moon.

Some of the concepts can best be understood if there is previous knowledge (like the distance to the moon) but this is on the whole a successful effort. Extensive notes in small print seem addressed to adults.

Kellogg's bouncy, vibrant pictures, however, are colorful and funny and indubitably addressed to children.

The Million Man March 

The number of people assembled on the wall for The Million Man March was especially important because of the name of this protest. African American leaders were proud of the number of people they were able to bring together in support of their cause and where upset when estimates stated that as few as 400,000 were actually in the crowd.

Read the article to see how many people were estimated by different agencies to have participated in the Million Man March and take special note of how they went about estimating the size of the assemblage.

If it is this difficult to count several hundred thousand, how is it possible to comprehend one billion?

The Million Man March was a mass gathering held in the United States, in Washington, D.C., on October 16, 1995. Under the leadership of Nation of Isl...
