M6.A.1.1.1 –
Represent common
percents as fractions
and/or decimals(e.g.
25% = ¼ =.25)-common
percents are 1%, 10%,
25%, 50%, 75%, 100%
.
M6.A.1.4.1 - Model
percents (through
100%) using drawings,
graphs and/or sets
(e.g., circle graph,
base ten blocks, etc)
FOCUS:
NUMBERS AND OPERATIONS
Terminating decimal – a decimal with a finite number of
digits; it ends
Repeating decimal – a decimal in which a digit or
digits repeat endlessly
PRACTICE QUESTION:
Find the decimal equivalent of 2/3. Is it a
terminating or repeating decimal?
Find the decimal equivalent of 3/20. Is it a
terminating or repeating decimal?
M6.A.1.1.2 – Convert
between fractions and
decimals and/or
differentiate between
a terminating decimal
and a repeating
decimal

M6.A.1.1.3 –
Represent a number in
exponential form
M6. A.1.1.4 –
Represent a mixed
number as an improper
fraction
M6.A.1.2.1 – Compare
and/or order whole
numbers, mixed
numbers, fractions
and/or decimals –(do
not mix fractions and
decimals - decimals
through thousandths).
Exponential form – a way of writing repeated
multiplication of a number using exponents
Mixed number – a number that combines a whole
number and a fraction
Improper fraction – a fraction in which the
numerator is greater than or equal to its
denominator
PRACTICE QUESTION:
Write 2 x 2 x 2 x 2 x 2 x 3 in exponential
form.
Write 3½ as an improper fraction.
Write 36/5 as a mixed number.
Greatest Common Factor (GCF) – the largest number that
is a factor of two or more numbers
Wednesday,
March 26, 2008 Least Common Multiple (LCM) – the smallest number,
M6. A.1.3.1 – Find
the Greatest Common
Factor (GCF) of two
numbers (through 50)
and/or use the GCF to
simplify fractions
M6. A1.3.2 – Find the
Least Common Multiple
(LCM) of two numbers
(through 50) an/or
use the LCM to find
the common
denominator of two
fractions
M6.A.1.3.3 – Use
divisibility rules
for 2, 3, 5, and/or
10 to draw
conclusions and/or
solve problems

M6.A2.11 – Complete
equations by using
the following
properties:
associative,
commutative,
distributive, and
identity
other than zero, that is a multiple of two or more
numbers
Rules of Divisibility
- a number is divisible by two if it ends in an even
number
- a number is divisible by 3 if the sum of its
digits is divisible by 3
- a number is divisible by 5 if it ends in 0 or 5
- a number is divisible by 10 if it ends in a 0
PRACTICE QUESTION:
Find the greatest common factor and least common
multiple of the following numbers:
4 and 36
Associative Property – the property that states the way
in which addends or factors are grouped does not affect
the sum or product
Commutative Property - the property that states the
order of the addends or factors does not affect the sum
or product
Distributive Property – multiplying a sum by a number
produces the same result as multiplying each addend by
the number and adding the products
Identity Property – the properties that state the sum
of any number and zero is that number and the product
of any number and one is that number
PRACTICE QUESTION:
What property is shown below:
12 + 0 = 12
a. Commutative Property
b. Identity Property
c. Distributive Property
What property is shown below:
3 + (4 + 9) = (3 + 4) + 9
a.
Commutative Property
b. Associative Property
c. Distributive Property

M6.A.3.1.1 – Use
estimation to solve
problems involving
whole numbers and
decimals (up to 2digit divisors and 4
operations)
M6.A.3.2.1 – Solve
problems involving
operations with whole
numbers, decimals
(through thousandths)
and fractions (avoid
complicated LCDs)straight computation
or word problems.
Use estimation to solve the problem:
352 + 812 – 99 =
a. 1,065
b. 900
c. 1,100
