Vocabulary

Welcome to the vocabulary page. All definitions are from the //Math Makes Sense-//Grade 6 textbook.


 * base:** the factor repeated in a power; for example, for the power 2 4, the base is 2
 * billion:**   one thousand million


 * common factor:** a number that is a factor of each of the gvien numbers; for example, 3 is a common factor of 15, 9, and 21
 * common multiple:** a number that is a multiple of two or more numbers; 6 is a common multiple of 2 and 3
 * composite number:** a number with three or more factors; 8 is a composite number because its factors are 1, 2, 4, and 8
 * congruent:** figures that have the same size and shape, but not necessarily the same orientation
 * cubic number:** a power with exponent 3; for example, 8 is a cube number because 8=2 3


 * equation:** uses the = symbol to show two things that represent the same amount
 * exponent form:** a method for writing repeated multiplication; for example, 3 5 means 3x3x3x3x3; 5 is the exponent
 * expression:** a mathematical statement with numbers and operations


 * greatest common factor:** the greatest number that divides into each number in a set; for example, 5 is the greast common factor of 5 and 10


 * integer:** the numbers ...,-3,-2,-1,0,1,2,3,...
 * inverse operation:** an operation that undoes another operation; addition and subtraction are inverse operations


 * least common multiple:** the first common multiple of two or more given numbers; for example, the least common multiple for 12 and 21 is 84
 * line symmetry:** a figure has line symmetry when it can be divided into two congruent parts; if we fold the figure along its line of symmetry, the parts coincide


 * million:** one thousand thousand


 * period:** in a large whole number, each group of 3 place values from right to left
 * power:** an expression of equal factors; for example, 4x4x4 can be expressed as 4 3 ; 4 is the base and 3 is the exponent
 * prime factorization:** a composite number written as a product of its prime factors; for example, 2x2x3x3 is the prime factorization of 36


 * recursive pattern:** a pattern in which each term can be found by applying the pattern rule to the previous term.
 * reflection:** a transformation that reflects a figure in a mirror line to create a congruent image
 * rotation:** a transformation in which a figure is turned about a fixed point called the turn centre


 * similar figures:** figures that have the same shape, though they may not have the same size
 * square number:** the product of a number multiplied by itself; for example, 25 is the square of 5


 * transformation:** a translation (slide), a reflection (flip), and a rotation (turn)
 * translation:** slides a figure from one location to another
