Definitions of Math Terms  \n\n| TERM | DEFINITION |\n| --- | --- |\n| acute angle | An angle with measure between zero degrees and 90 degrees. |\n| acute triangle | Triangle with all interior angles measuring less than 90 degrees . |\n| addend | A number used in the mathematical operation of addition (e.g. , 6 + 8 = 14, 6 and 8 are addends) . |\n| addition | A mathematical operation that combines two or more numbers to calculate a sum. |\n| adjacent angle | Two angles \u003CAOC and \u003CCOB, with a common side OC , are adjacent angles if C is in the interior of \u003CAOB. |\n| algebraic expression | A group of numbers, symbols and variables that express a single or series of mathematical operations (e.g. , 2x 􀀎 4 􀀐 16y ) . |\n| algebraic\u003Cbr>form/notation | An algebraic description written in terms of numbers, symbols and variables . |\n| algorithm | A set of step-by-step instructions for completing a task that can be generalized to other tasks, problems or situations. |\n| analog clock | A device for the measurement of time that has numbers 1 to 12 around a face, with an hour, minute and second hand that shows a continuous sweep of time. |\n| angle | A geometric figure consisting of the union of two rays that share a common endpoint (vertex) . |\n| angle measure | The measure (in degrees or radians) of the arc formed by two rays with a common endpoint (vertex) . |\n| arc | Connected portion of a circle.\u003Cbr>|\n| area | A two-dimensional space measured by the number of non-overlapping unit squares or parts of unit squares that can fit into the space. |\n|  |  |\n\nK-5 Definitions of Math Terms  \n\n| area model | A model for multiplication problems, in which the length and width of a rectangle represents the factors.\u003Cbr>|\n| --- | --- |\n| array | A rectangular arrangement of objects or elements organized into rows and columns, or a set of objects or elements organized into a specific pattern . |\n| arrow notation/“arrow way” | \u003Cbr>Simplifying strategy using arrows to show how a number can be simplified to add in addition or subtraction. |\n| associative property | Addition: changing the grouping of terms in a sum without changing the sum.\u003Cbr>Multiplication: changing the grouping of factors in a product without changing the product. |\n| attribute of a figure | A property or common feature of a set of objects or elements. |\n| bar graph | A representation of the length of either vertical or horizontal bars used to enumerate and compare data. |\n| benchmark | A commonly known point of reference from which measurements may be made (e. g. , four quarters make a whole) . |\n| benchmark fraction | A commonly known fraction that serves as a meaningful reference point for measurement comparison. |\n| bundling/unbundling | Putting smaller units together (or apart) to make a larger (smaller) one, example; putting 10 ones together to make a ten or 10 tens together to make a hundred. |\n| capacity | The amount of space in units or cubes that can fit into a solid (Note: also referred to as volume. ) . |\n\nK-5 Definitions of Math Terms  \n\n| centimeter | Unit of measurement. |\n| --- | --- |\n| chip model | Drawing dots on a labeled place-value chart.\u003Cbr>\u003Cbr>The number represented is 236. |\n| circle | A set of points in a plane that are equidistant from a given point , called the center. |\n| collinear | Three or more points that lie on the same line. |\n| column | Vertical direction used in an array. |\n| common algorithm | A set of step-by-step instructions that are well known by most practitioners and are frequently used (e.g. , borrowing, carrying) . |\n| common\u003Cbr>denominator | A number divisible by all of the denominators in a set of fractions. |\n| common factor | A whole number that divides without remainder into two or more non-zero numbers. |\n| common multiple | A whole-number multiple of two or more given numbers ( e.g. , 48 is a common multiple of 2, 3 and 4) . |\n| commutative property | Addition: the addition of terms in any order obtains the same sum (e.g. , a 􀀎 b 􀀎 c 􀀠 d ,
