the volume of a unit cube
What is a CUBIC UNIT
the amount of space inside a solid figure.
What is VOLUME
One side of a prism, usually considered to be the side shown as the bottom.
What is BASE (of a prism)
the products you get in each step of the partial- products strategy. 28 x 6= 20 x 6 = 120
8 x 6 = 48
120 and 48 are partial products
What is a PARTIAL PRODUCT
The number by which another number is divided
What is DIVISOR
a two-dimensional figure, such as a circle, triangle, or a rectangle
What is a PLANE FIGURE
The amount of space inside a closed two dimensional figure.
What is AREA
a mathematical relationship that is expressed in the form of an equation
What is a FORMULA
the result of multiplication
What is a PRODUCT
the quotients you get in each step of a partial-quotient strategy
What are PARTIAL QUOTIENTS
a three-dimensional figure
What is a SOLID FIGURE
a flat surface of a solid shape
What is FACE
when one of the factors of a product is written as a sum, multiplying each addend by the other factor before adding does not change the product.
3 x 12= (3 x 10) + (3 x 2)
What is DISTRIBUTIVE PROPERTY
Math operations that undo each other
Addition undoes subtraction
Multiplication undoes division
What is INVERSE OPERATIONS
the result of division
What is a QUOTIENT
A cube with side lengths of 1 unit. A unit cube is said to have one cubic unit of volume andit can be used to measure the volume of a solid figure.
What is a UNIT CUBE
a solid figure with six rectangular faces
What is a RECTANGULAR PRISM
A set of routine steps used to solve problems
What is an ALGORITHM
The number that is divided by another number
What is a DIVIDEND
A square with side lengths of 1 unit. A unit square is said to have one square unit of area, and can be used to measure the area of a plane figure.
What is a UNIT SQUARE
the area of a unit square
What is a SQUARE UNIT
a number that is multiplied
What is a FACTOR
an operation used to separate a number of items into equal-sized groups
What is DIVISION
