Big numbers: blast off with your students on an exploration of big numbers.What's a Googol An extremely large number. The term was coined by Milton Sirotta, a young nephew of American mathematician Edward Kasner (1878-1955), who said a googol was 1 followed by 100 zeros (10100). ? Give students hands-on experience with one of the very biggest numbers! Introduce the word "googol" and explain that one googol is the number 1 followed by 100 zeroes. Then divide up 100 paper plates among students and ask them to trace the inner circle of the plates to make zeroes. Pass out 33 sticky notes and have students write a comma on each while you cut a "1" out of a piece of construction paper. Locate a long wall in a hallway, the cafeteria cafeteria: see restaurant. , or the gym. Then attach the number 1, all of the plates, and the commas in order. Your class has just made a googol! Invite the whole school to stop by and take a look at your big number. [ILLUSTRATION OMITTED] Using The Reproducible re·pro·duce v. re·pro·duced, re·pro·duc·ing, re·pro·duc·es v.tr. 1. To produce a counterpart, image, or copy of. 2. Biology To generate (offspring) by sexual or asexual means. Use the Big Numbers Reproducible on page 56 to give students practice reading and writing big numbers. The distance between the sun and planets appears in words on the page. Ask students to read these distances, then write them as numerals. For example, if they read "sixty-two million miles," they will write "62,000,000." You might have pairs work together, reading the numbers aloud to each other. This activity also helps children understand the relative distances of planets from the sun. [ILLUSTRATION OMITTED] Making a Million In this activity, students practice multiplication multiplication, fundamental operation in arithmetic and algebra. Multiplication by a whole number can be interpreted as successive addition. For example, a number N multiplied by 3 is N + N + N. skills while observing the difference between quantities of 1,000, 100,000, and one million. First, divide the class into 10 groups. Give each group one cup of salt and a plastic cup. Tell students to assume that one pinch pinch, n a small amount of chewing tobacco (snuff) an individual takes to use the substance for its desired effect. A “pinch” is called a quid in Britain. of salt contains 1,000 grains. Have each group fill a cup with 100 pinches to get 100,000 grains of salt. Then bring the class together and have groups pour the cups of salt into a bowl. This will total 1,000,000 grains, so kids can say they know what one million looks like! [ILLUSTRATION OMITTED] BIG NUMBERS IN SPACE [ILLUSTRATION OMITTED] Directions: Check out how far each planet is from the sun! Then, in the boxes, write the number of miles in numerals instead of words. For example, if you read "sixty-two million miles," you would write "62,000,000." RELATED ARTICLE: Understanding Big Numbers Share these definitions to boost your students' comprehension comprehension Act of or capacity for grasping with the intellect. The term is most often used in connection with tests of reading skills and language abilities, though other abilities (e.g., mathematical reasoning) may also be examined. of big numbers. * MILLION: One million is a thousand thousands. A pile of one million strands of hair would reach seven stories high! * BILLION: One billion is a thousand million. A billion seconds is about 32 years. * TRILLION One thousand times one billion, which is 1, followed by 12 zeros, or 10 to the 12th power. See space/time. (mathematics) trillion - In Britain, France, and Germany, 10^18 or a million cubed. In the USA and Canada, 10^12. : One trillion is a thousand billion, or a million million. If a trillion kids stood on top of each other, they would reach beyond Jupiter. * ZILLION: A zillion is certainly a lot, but it's not a real number. * INFINITY infinity, in mathematics, that which is not finite. A sequence of numbers, a1, a2, a3, … , is said to "approach infinity" if the numbers eventually become arbitrarily large, i.e. : This term is represented by the symbol [infinity]. It refers to time, space, or a quantity that has no limit or end. |
