Place Value and Rounding
• Numbers to the right of the
decimal point end in “ths”
• Read the number before the
decimal; read decimal point as
“and”; read the number after the
decimal; finish with the place
value…one million, three hundred
forty two thousand, three hundred
sixty five and one thousand four
hundred twenty seven tenthousandths
Essential Learning Review
Place Value and Rounding
• To round – identify the place
you are rounding; every digit in
front of it stays the same; look at
the place value to the right; 0-4
your number stays the same; 5-9
your number increases by 1; all
digits to the right become zero
• Round to the hundredths

Fractions
Simplifying Fractions
• Divide the numerator and
denominator by the same
number
– If you divide by the GCF
you are done in one step
– You know you can stop
dividing when there is no
number other than 1 that
goes into the numerator
and denominator
Equivalent Fractions
• Multiply or divide the
numerator and
denominator by the same
number

• For every fraction
there is a decimal
with the same name!

Decimals
Fraction versus
decimals
• It’s very important that
the denominator of
your fraction is 10,
100, 1000 (or any
power of 10) because
these match your
decimal place values.
Example:
Change your
denominator to a
2 power of 10 (multiply
5 5 x 2 = 10). Then
multiply your
numerator by the
same number.

• Line up place values
and decimal point.
• Input zeros in empty
spaces.
• Bring decimal point
down.
• Add or subtract like
normal.

Geometry
Basic Facts
• Point – a definite location in space
• Line – goes on “infinitely” in both directions
• Line segment – part of a line
• Ray – has one endpoint and goes on infinitely in one
direction
• Parallel lines – will never intersect
• Perpendicular lines – intersect to form right angles ┼

Patterns and Algebra
Variable
Expressions
• Letter or symbol that
takes the place of a
number
• A mathematical
phrase including at
least one operation
• No equal sign
Examples of variables:
X, a, 
Examples:
X+5, 3y, 5b-7
Essential Learning Review
Patterns and Algebra
Equations
• A mathematical
sentence containing
an equal sign
Example:
P+3=9
Evaluating Expressions
• You must be given the
value of the variable
to find the solution
Example: x=9
x+5 plug in 9 where the x is
9+5 = 14
Essential Learning Review
Patterns and Algebra
Solving Equations
• To find the solution
you must figure out
what value of the
variable will make the
sentence true
Example:
P+3=9
P must equal 6
because 6 + 3 = 9

Data Analysis, Statistics and
Probability
Mean, Median, Mode
and Range
• Mean – the average
– Add all the numbers
together and divide by
how many numbers
there are
• Median – the middle
number
– Line the numbers up
from least to greatest
and find the number in
the middle
– If there are 2 numbers
in the middle – find the
mean of those two
numbers
Essential Learning Review
Data Analysis, Statistics and
Probability
Mean, Median, Mode
and Range
• Mode – the number
that occurs most often
– There may be no
modes
– There may be more
than one mode
• Range – the
difference between
the highest and
lowest numbers
– Subtract the highest
number minus the
lowest number
