Name:_________________ 5th Grade- Unit One Vocabulary Vocabulary Definition Composite: a whole number having more than two factors Coordinates The numbers in an ordered pair Greatest common factor Function Function Table the greatest factor that two or more numbers have in common A relationship between two variables in which one quantity depends on the other A table that matches each input value with an output value. The output values are determined by the function. the smallest number, other than zero, Least common multiple that is a common multiple of two or more numbers Example Number 4 6 8 9 Factors 1, 2 ,4 1, 2, 3, 6 1, 2, 4, 8 1, 3, 9 (6, 8 ) 18: 1, 2, 3, 6, 9, 18 30: 1, 2, 3, 5, 6, 10, 15, 30 6 is the GCF of 18 and 30 𝐟 = 𝟑𝐞 − 𝟐 This equation is a function d=6c d c 0 6 12 18 0 1 2 3 6: 6, 12, 18, 24, 30 9: 9, 18, 27, 36 18 is the LCM of 6 and 9 Multiples The products of two whole numbers Multiples of 9 are.. Percent the ratio of a number to 100 40/100 = 40% Prime Number a whole number greater than 1 that has exactly two factors, one and itself 9, 18, 27, 36, 45 Number 2 3 5 Factors 1, 2 1, 3 1, 5 Anne Flores 10’ Name:_________________ Products Ratio Rules of divisibility The answer to a multiplication problem the comparison of two numbers by division special tests to determine if a particular integer (positive and negative whole numbers and 0) is a factor of a given number 𝟗 𝐱 𝟑 = 𝟐𝟕 27 is the product Compare red counters to all counters: Ratio: 2 to 5 𝟏𝟎 𝟐, 𝟒𝟓𝟎 = A number is divisible by 10 if it ends in a 0 Anne Flores 10’ Name:_________________ 5th Grade Math Vocabulary Expressions A mathematical phrase or a part of a number sentence that does not have an equal sign. Equation A numerical or algebraic sentence that shows that two quantities are equal Difference The answer to a subtraction problem Divisible Capable of being divided so the answer is a whole number without a remainder. Factors A number multiplied by another number to find a product Multiples A product (the answer) of two whole numbers Order of Operations Rules for performing operations in expressions with more than one operation. Sum The answer to an addition problem Quotient The number, not including the remainder, that results from dividing. 𝟗𝐱𝟑 or A+8 𝟗 𝐱 𝟑 = 𝟐𝟕 or A + 8 = 12 𝟗−𝟑=𝟔 9 and 3 are factors 27 27 is divisible by 3 and 9 𝟗 𝐱 𝟑 = 𝟐𝟕 9 and 3 are factors 𝟗 𝐱 𝟑 = 𝟐𝟕 27 is a multiple of 9 𝐏. 𝐄. 𝐌. 𝐃. 𝐀. 𝐒 𝟗 + 𝟑 = 𝟏𝟐 9 and 3 are factors 𝟗 ÷ 𝟑=𝟑 3 is the quotient Anne Flores 10’
