5. WHY I LOVE MATH
“We all use math every day-
to predict weather, to tell time,
to handle money.
Math is more than formulas and equations.
It's logic. It's rationality. It's using your mind to solve
the biggest mysteries we know.”
-Numb3rs introduction

10. EXPECTATIONS..
What do you expect from a teacher?
What do you expect from this math class?
11. I EXPECT…
You to respect me, and I will in turn respect you.
You to respect others in the class and allow
everyone a chance to learn
12. BRUSH UP ON NEEDED SKILLS
Not knowing a skill can hinder your ability to take the
GED test. It may take longer to figure out a problem.
For example: multiplication facts
One way to brush up on this skill is make some flash
cards and practice daily!
13. VOCABULARY
Many people miss test questions because they lack
understanding of certain math terms.
By understanding the meanings of the math terms, the
problems can then be solved correctly .
So we will be focusing on the math terms as well as the
math process
15. PLACE VALUE
• Place value is the basis of our entire number system
• Before any numbers can be added, subtracted, multiplied or
divided, the place value of numbers must be understood.
• Each place has a given value, therefore each digit has a
given value.
• A place value system is one in which the position of a digit in
a number determines its value.
Example: 127,854
Hundred Ten
Thousands Hundreds Tens Ones
Thousand Thousand
1 2 7 8 5 4
16. In the number 456, each digit has a specific value.
4 5 6
hundreds tens ones
4 x 100 5 x 10 6x1
The value for each number is as follows:
400 + 50 + 6 =
456
17. PLACE VALUE PRACTICE
What place value is the number 5 in each of these
numbers:
5,423
758
965
50,012
8,652
588
501,468
18. GUIDED PRACTICE: PLACE VALUE
Write the value for the underlined number below.
1. 478 ___________
2. 985 ___________
3. 225 ___________
4. 7361 ___________
19. GUIDED PRACTICE: PLACE VALUE
Write the value for the underlined number below.
1. 478 8 ones
___________
2. 985 9 hundreds
___________
3. 225 ___________
2 tens
4. 7361 ___________
7 thousands
20. DECIMAL PLACE VALUE
Example: 0.78216
Ten Hundred
Tenths Hundredths Thousandths
Thousandths Thousandths
7 8 2 1 6
21. DECIMAL PLACE VALUE
What place value is the 7 in each of these decimals?
0.127
0.7
0.37
0.4567
22. Have you notice the pattern for the place values?
Notice all the decimal place names end in –ths.
They represent fractions or part of one unit.
23. ESTIMATION
Estimation is finding a number that is close
enough to the right answer.
You are not trying to get the exact right answer
When would be a good time to use estimation in your
life?
In mathematics we often stress getting an exact
answer.
But estimation can save you from making mistakes
with your calculator:
24. For example: you are calculating 107 times 56, and
the calculator shows this:
952.00
Is that right?
"107 times 56 is a bit more than 100 times 50,
which is 5,000"
Ooops! you must have typed something wrong, in
fact you pressed 17×56 (you left out the zero), and
without estimating you could have made a really big
mistake!
25. ROUNDING
Rounding means reducing the digits in a number
while trying to keep its value similar.
The result is less accurate, but easier to use.
How to Round
Underline the digit in the place you are rounding to,
this is the last digit you need to keep
Leave the underlined digit the same if the next
digit to the right is less than 5
But increase the underlined digit by 1 if the next
digit to the right is 5 or more
26. EXAMPLES OF ROUNDING
Round 74 to the nearest 10
Round 86 to the nearest 10
3.1416 rounded to hundredths
1.2635 rounded to tenths
5.7536 rounded to 3 decimal places
27. Round 0.599 to the hundredths place
Round 178.9 to the ones place
Round 84.84 to the tenths place
Round 0.1254 to the thousandths place
29. WHAT ARE THE 4 BASIC MATH OPERATIONS?
Addition Multiplication
Subtraction Division
It doesn’t matter what kind of math problems are being
solved. These are the only math operations used.
30. DEFINITIONS: BASIC OPERATIONS
Addition (+) Adding two or more numbers together.
Subtraction (-) Finding the difference between numbers.
Multiplication (x) is repeated addition.
5 x 3 is the same as 5 + 5 + 5 or 3 sets of 5 = 15
3 x 5 is the same as 3 + 3 + 3 + 3 + 3 or 5 sets of 3 = 15
Division (÷) is the splitting into equal groups or parts; the result of
sharing.
There are 12 chocolates, and 3 friends want to share them, how
do are the chocolates divided?
4 each
32. MULTIPLICATION
Always think of multiplication as just adding groups
of numbers.
If you have 4 x 3, it simply means 4 groups of 3.
Within these four groups, there are three triangles.
3 3 3 3
How many triangles? 3 + 3 + 3 + 3=12
4 groups of 3 = 12 4 x 3= 12
33. The numbers multiplied together in a multiplication
problem are known as factors.
In 3 x 6 = 18; 3 and 6 are the factors of this problem
3 and 6 are factors of 18
The answer to a multiplication problem is know as
the product.
In 3 x 6 = 18, the answer 18 is the product.
34. MULTIPLICATION SYMBOLS
The multiplication problems can be written in many
forms –
The format that is most recognizable is using the “x”
between two numbers:
Example: 2 x 3
Using a dot between numbers also means multiply.
Example 5 • 4
Parenthesis around a number means multiply.
Example: (9)(6)
Example: 5(3)
Algebraic expression
Example: 5n = (5 x n)
40. MULTIPLICATION AND DIVISION ARE
OPPOSITE OPERATIONS
For each division fact, there is another division fact.
For example:
72 9=8 and 72 8=9
For each of those division facts, there is a related
multiplication fact.
For example:
8 x 9 = 72 and 9 x 8 = 72
41. HOW TO SOLVE WORD PROBLEMS
Word problems often scare people. There is no secret to
solving word problems. Experience and practice are the
best help. But you can use these 5 steps to organize your
thinking about word problems.
1. Understand the question--What is the problem asking?
2. Decide what information is needed to solve the
problem.
3. What operations will be used?
4. Solve the problem and check your work
5. Does the answer make sense and did you answer the
question being asked?
42. SOLVING WORD PROBLEMS
There are 3 main tools for solving word problems:
1. Knowing the definitions or main idea behind the different
operations.
2. Knowing the Key Words for choosing the correct operation.
3. Asking the right questions when solving the word problem.
43. KEY WORDS:
