area model
A model for multiplication in which
the length and width of a rectangle represent the
factors, and the area of the rectangle represents
the product.
place value
A system in which the value of a digit
depends on its place or position in a number. In
our base-10 system for writing numbers, moving a
digit one place to the left makes that digit worth
10 times as much. Moving a digit one place to
the right makes that digit worth 1
_ 10 as much. For
example, in the number 450 the 4 in the hundreds
place is worth 400, but in the number 45 the 4 in
the tens place is worth 40.
dividend
In division, the number that is being
divided. For example, in 35 ÷ 5 = 7, the dividend
is 35.
divisor
In division, the number that divides
another number. For example, in 35 ÷ 5 = 7, the
divisor is 5.
expanded form
A way of writing a number as the
sum of the values of each digit. For example, in
expanded form, 356 can be written 300 + 50 + 6
or (3 ∗ 100) + (5 ∗ 10) + (6 ∗ 1).
exponent
A small, elevated number used in
exponential notation to indicate how many times a
factor should be repeated. For example, in 104, the
exponent is 4.
power of ten
A whole number that can be written
as a product of 10s. For example, 100 is equal to
10 ∗ 10 and can be written 102. 100 is called "the
second power of 10," "10 to the second power," or
"10 squared."
exponential notation
A way to show repeated
multiplication by the same factor. For example, 103
is exponential notation for 10 ∗ 10 ∗ 10.
quotient
The result of dividing one number by
another number. For example, in 35 ÷ 5 = 7, the
quotient is 7.
remainder
The amount left over when one
number is divided by another number. For example,
if 38 books are divided into 5 equal piles, there
will be 7 books per pile, with 3 books left over.
Represented in symbols, this is 38 ÷ 5 → 7 R3.
number model
A number sentence or expression
that models a number story or real-world
situation.
standard notation
The most familiar way of
representing whole numbers, integers, and
decimals. In standard notation numbers are
written using the base-10 place-value system. For
example, standard notation for three hundred
fifty-six is 356.
