Give a definition of a
prime number.
A number that has exactly two
unique factors, 1 and itself. The
numbers 2, 3, and 5 are some
examples of prime numbers.
Use three math terms you learned
in this unit to describe the
number 36.
Possible Answers:
It is composite
Even
Square number
Multiple of 2,3,4,6,12,18
36 is a factor of 36,72 etc.
What do the words product, sum,

All terms describe the answer as a
result of an operation: multiplication,
addition, division, and subtraction,
respectively
What are the divisor and
dividend, and how are
they related?
The divisor is the number in a
division problem that divides into
another number, known as the
dividend
Explain how a multiple
and a factor are alike
and different?
A multiple and factor both are terms used to
describe multiplicative relationships: a factor is a
number that divides exactly into a given whole
number, and a multiple is a number that is the
product of a given number and a whole number
What remainders are
possible when the divisor is
12?
There are 12:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
10 and 11
Write a related sentence
that uses multiplication for
45 6
(7X6) + 3= 45
The quotient is 13, the divisor
is 6 and the remainder is 3.
What is the dividend?

John said that 23 0=0 but Carla
disagreed and said there is no
answer. Who is right? Explain.
Carla is right since the multiplication sentence
that corresponds to the division problem is 0 X
0 = 23, which is false. No answer is possible,
which means that the problem is undefined.
Make up a division word
problem with a quotient of 3 ½
in which the answer includes 3
as the remainder.
