1. EOG Math Strategies Race to the Finish!
Cathy Barlow - Hudson Middle School
Sharon Norman – Leland Middle School

2. Some important things
for you to know about the
Math EOGs…

3. The math EOGs were
brand new two years ago
the questions are HARDER
the passing grade is HIGHER!

4. What does that mean to us?
The state has made the EOGs more
challenging…
We have to work harder to be prepared…
What worked before may not work now…

5. Not only do you need to work HARDER,
BUT you also need to work SMARTER!
Let’s look at some STRATEGIES that will help you “work smarter”…

6. Come to school EVERYDAY during EOGs!
May
May
May 26 27 28

7. Get a good night’s sleep before the EOGs!

8. Eat a good breakfast
before the EOGs!

9. Remember, work slowly and carefully on the tests!
“I tried my very best!”

10. Try your hardest on EVERY problem – don’t give up!
I’ll just fill in any circle – I’ll just fail anyway!”

11. If you can narrow it down to two good choices – choose the best of the two!
“Well, I know it’s either A or C, but I think C is better so I’ll mark C!”

12. Let’s practice and learn some tips for success…

13. 1.) A class is conducting a probability experiment using the spinner shown. The table shows the results of spinning the spinner 200 times. What is the experimental probability that the spinner will land on blue on the next spin?

20. It does not look like the answer is here, BUT…. It is!
Sometimes they make the answers very tricky!
It does not look like the answer is here, BUT…. It is!
Here’s a hint:
Always look for answers that may be simplified or written in another “form”!

21. The answer is B) 4/95 Don’t let them trick you!
Always look for answers that may be simplified or written in another “form”!

WRONG answers that students often pick are usually included in the answer choices.
Think before you choose!

24. The answer is
B) 15,625
Remember, common wrong answers are often included as choices – take your time and think before you write!!!!

25. 5.) What is 7/8 written as a percent and as a decimal number?

least to greatest !
Remember:
Numbers are easiest to compare when they are written in the same form!
ALL negatives are less than ALL positives!
Whole numbers are greater than fractions!

30. The answer is
D) 1, 2/5, , %
To compare numbers, change them to the same form – usually decimals!
Be sure you know WHAT the question is asking for!!

35. Remember, you want to work “smarter” - NOT “harder”!
Always ESTIMATE before you work the problem…
Hmm…
This helps you ELIMINATE choices AND helps you know if your answer is REASONABLE!

36. The answer is
B 20 feet
ESTIMATING before you work a problem helps you eliminate choices and determine if your answer is REASONABLE!

37. 9.) What is written in
standard form?
A. 2,350 B C
D. 2,350,000

38. You can think… If a question seems confusing think about
it in small parts first!
You can think…
1.) Do I know what 10-4 means?
If so, use the calculator to find the answer!
2.) Then look at the rest of the problem….
Do I know what the dot means between
the numbers? If so use the calculator….

39. The answer is C) 0.000235 Remember, if you are confused –
start somewhere! See if you can
begin with a small part of the
problem first!

Remember that numbers get smaller
as you go left on the number line!

45. The answer is D) – ½ < - 0.2
Don’t JUMP at an answer –
THINK before you write!

order and it does
not make a different
arrangement or
change the item,
then it is a
combination!
Example: 5c3
If you change the order
and it makes a different
arrangement, then it is a
permutation!
Example: 5P3

“About the origin” means around (0,0) on the coordinate grid… staying the same distance from that point!
90 means the new “image” will form a right angle with the first figure.

69. The answer is C) quadrant III
Quadrants are numbered from the top right side and go COUNTERCLOCKWISE!!!
