add -ANSWER To combine, put together two or more quantities.
addend -ANSWER Any number being added.
additive comparison -ANSWER Problems that ask how much more (or less) one amount is
than another.
algorithm -ANSWER A step-by-step method for computing.
angle -ANSWER Two rays that share an endpoint.

turned from the other side. A one degree angle turns through 1/360 of a full circle.
arc -ANSWER Part of a circle between any two of its points.
area -ANSWER The measure, in square units, of the inside of a plane figure.
area model -ANSWER A model of multiplication that shows each place value product.
array -ANSWER An arrangement of objects in equal rows.
Associative Property of Addition -ANSWER Changing the grouping of three or more
addends does not change the sum.
Associative Property of Multiplication -ANSWER Changing the grouping of three or more
factors does not change the product.
attribute -ANSWER A characteristic of an object, such as color, shape, size, etc.
benchmark fraction -ANSWER Fractions that are commonly used for estimation.
capacity -ANSWER Capacity refers to the amount of liquid a container can hold.
centimeter (cm) -ANSWER A metric unit of length equal to 0.01 of a meter.
, circle -ANSWER A plane figure with all points the same distance from a fixed point called
a center.

common
multiple of the denominators.
Commutative Property of Addition -ANSWER Changing the order of the addends does not
change the sum.
Commutative Property of Multiplication -ANSWER Changing the order of the factors does
not change the product.
compare -ANSWER To decide if one number is greater than, less than, or equal to.
comparison bars -ANSWER Used to represent larger and smaller amounts in a
comparison situation. Can be used to represent all four operations. Different lengths of
bars are drawn to represent each number.
compose -ANSWER To put together components or basic elements.
composite number -ANSWER A number greater than 0 that has more than two different
factors.
congruent -ANSWER Having exactly the same size and shape.
cup (c) -ANSWER A customary unit of capacity.
1 cup = 8 fluid ounces.
