|acute||angle greater than 0 and less than 90 degrees|
|algorithm||steps used to solve a problem|
|associative properties||the answer to a problem will be the same regardless of how you group it.
ex. a+b will give you the same answer as b+a
|bivariate data||data that has two variable.|
|Box-and-whisker plot||pictorial representation of the median of data and the range of all data from highest to the lowest quartile.|
|common factors||a number that divides evenly into two or more expressions|
|common referent||something that is familiar that can be used to understand something that is less familiar.
ex. A loaf of bread is about 12 inches long.
|communitive property||numbers order in a math problem can be changed (14+2 will give you the same answer as 2+14) but the answer remains the same.|
|compatible numbers||a pair of numbers that are easy to work with mentally. Ex. 141 x 4 Could be estimated by 140 X 5|
|congruent||same size and same shape|
|correlation (hint: relation)||the relationship between 2 sets of data|
|coefficient||A number or symbol multiplied in an algebraic term.
ex. 5a – 5 is coeffient and a is the variable.
|distributive property||Math property that states that multiplying a sum by a number is the same as multiplying each addend (the numbers being added) by the number and then adding the products.
Ex a x (b + c) will get same answer as (a x b) + (a x c)
|dividend||number that is divided by another 20/4
The 20 is being divided and called dividend.. The 4 is the number dividing and is called the divisor. The answer is called the QUOTIENT.
|equation||a math sentence with an equal sign|
|divide||to evenly seperate an amount into equal groups.
Ex. Mom buys Reese Cup and says give 1/2 to your brother. You divide it by giving 1 to brother and 1 for yourself.
|equivalent||two numbers or expressions are equal
Ex. 210 = 200+10

|face||flat surface on a solid figure|
|function table||table that lists pairs of numbers that show a function.|
|mean||the average of a set of numbers
add all numbers and then divide by the number of addends
|mode||the number in a data set that occur MOST
2,3,2,2 the the mode is 2
|median||the middle number when data is arranged from least to greatest|
|natural numbers||the counting numbers|
|negative numbers||numbers less than zero and to the left of the zero on the number line.|
|perfect square||the product (answer of multiplication) of a number multiplied by itself.
Ex. 16 is the perfect square of 4 because 4×4
