What words can we use to describe numbers?  How does that help us use and understand numbers in our daily life?

 Words That Describe NumbersComic Strip Creator Teams Definitions Ways that word helps us to learn math and succeed in daily life? Every number has a name2,000,000 vs 2 vs 200 You have to understand the number’s value (how big it is).We have to understand place value. You can get cheated w/moneyUnderstand the value of items*Shel Silverstein poem EvenKya/Laura It can be divided into two equal groups. To divide into two groups.What’s it’s connection to symmetry.(E + E = E) OddLiang/Shawn It can’t be divided into two whole numbers. Half of the digits make odd numbers when you’re talking about single digit numbers.Add two odds and you get an even (two even groups of odd, make even) (O + O = E)Add odd plus even always equals odd. (E + O = O) Digits:  0, 1, 2, 3, 4, 5, 6, 7, 8, 9There are only ten digitsHaeun/Aarushi The digits are the figures the that make up all numbers to “infinity and beyond.” Working with money.Write all numbers. Whole Number-Gabriella No decimals, no fractions -- it’s the whole thing such as 1, 2, 3, …..35, 36...100 Multiples“Buzz Lightyear Numbers”Aidan/Kevin It’s counting by a specific number.  The multiples of 12 are 12, 24, 36, 48. . . Multiples go to infinity and beyond. . . Factor1 is a factor of all numbers. 2 is a factor of all even numbers.Yana/Tamira Factors are numbers you multiply to get a product (answer in multiplication) The factor pairs for 24 are:1X242X123X84X6 Square NumbersJaden/Modib Numbers that make a square when you draw an array like this 4 is a square number: Square numbers have two factors that are the same such as 3X3 = 9, 9 is the square number.  16 is square because 4 X 4 = 16. Prime 2 is the only even prime #Dravin/Marcos It’s a number that can only be divided by one and itself or it only has one factor pair: 1 X itself. 2,3,5,7,11,13,17,19,23,29,31,37, 41, 43, 47, 51, 53, 59, 61, 67, CompositeAlex/Dylan They two or more factor pairs, they are the opposite of primes Composite Numbers Less than twenty:4: 1X4, 2X26: 1X6, 2X38: 1X8, 2X49: 1X9, 3X310: 1X10, 2X512: 1X12, 2X6, 3X414: 1X14, 2X715: 1X15, 3X516: 1X16, 2X8, 4X418: 1X18, 2X9, 3X620: 1X20, 2X10, 4X5 Zero is a whole number, not composite or prime one not composite or prime ProductArtur/Kayla Result of Multiplying___X___ = Product SumGabriella/Nich Result of adding___+___= sum DifferenceAngela/Elissa Result of Subtracting___-____= Difference Quotient Result of division____/_____= quotient Ascending Order Going up in value Consecutive Order Number in order Descending Order Going down in value
