  1. EOG Math Strategies Race to the Finish! Sharon Norman, Leland Middle, Brunswick County

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

  3. The math EOG’s were • brand new two years ago • the questions are HARDER • the passing grade is HIGHER!

  4. What does that mean to us? • We have to work harder to be prepared… • The state has made the EOGs more challenging… • 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 EOG’s! May May May 21 20 22

  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? Spinner Results Blue 76 Red 27 Green 52 Yellow 45 R R Y B Y B B G 1 4 3 8 19 50 37 100 A. C. D. B.

  14. Math vocabulary is very important! Do you know what the words experimental probability mean? Slide 13 CLICK HERE WHEN DONE

  15. YES !!! Math vocabulary is very important! Try to really think about the meaning of the math words!

  16. 2.) Simplify: 9 + 63 ÷ (9 – 8) 32 A. -476 B. 648 C. 576 D. 0

  17. Slide 16 Click here ALWAYS use Order of Operations! 1.) Parenthesis (and other grouping symbols) 2.) Exponents 3.) Multiplication or division, left to right 4.) Addition or subtractrion, left to right

  18. Remember order of operations - “Please excuse my dear Aunt Sally.” YES !!!

  19. 3.) A bag contains 6 pink, 8 white, 4 green, and 2 blue ribbons. Jasmine picks ribbons out of her bag at random. She picked one ribbon out of the bag, put it aside, and then picked out a second ribbon. What is the probability that the first ribbon is white and the second is blue? A. 1/25 C. 4/25 D. 1/4 B. 4/95

  20. 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”! CLICK HERE WHEN DONE Slide 20

  21. YES !!! Don’t let them trick you! Always look for answers that may be simplified or written in another “form”!

  22. 4.) What is the value of 253? A. 565 B. 15,625 C. 5,165 D. 75

  23. DON’T FALL for common mistakes! WRONGanswers that students often pick are usually included in the answer choices. Think before you choose! CLICK HERE

  24. YES !!! 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? A. 78%, 0.78 B. 85%, 8.5 C. 87.5%, 0.875 D. 92.5%, 92.5

  26. Think carefully about the meaning of math symbols… HINT: A fraction bar has a special meaning in math! Slide 23 Click here

  27. YES !!! Pay special attention to math symbols on the EOG! Think about their meaning!!!

  28. 6.) Which list shows the numbers in order from greatest to least? A. 2, 5/9, 1.815, 67% B. 0, 33.3%, 3/4, 4.2 C. 99%, 10, 8/9, 0.36 D. 1, 2/5, 0.16, 11.5%

  29. Read carefully to see what the question asks for: greatest to least OR least to greatest! • Remember: • Numbers are easiest to compare when they are written in the sameform! • ALL negatives are less than ALL positives! • Whole numbers are greater than fractions! Click here Slide 28

  30. YES !!! To compare numbers, change them to the same form – usually decimals! Be sure you know WHAT the question is asking for!!

  31. 4 7.) Evaluate: 9 A. 13 B. 6561 C. 176 D. 36

  32. If you are unsure of a mathsymbol – try looking on your calculator! Many math symbols are on the calculator! Slide 19 Click here

  33. YES !!! Remember, your calculator is a tool so if you are confused: Look for keys on the calculator that might help you!

  34. 8.) A carpenter built a gazebo with a floor in the shape of an octagon. If each side of the octagon measures 2 ½ feet, what is the perimeter of the gazebo floor? A. 35 feet B. 20 feet C. 13.2 feet D. 52.48 feet

  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! Slide 34 Click here

  36. YES !!! ESTIMATINGbefore you work a problem helps you eliminate choices and determine if your answer is REASONABLE!

  37. 9.) How is 2.35 10-4 written in standard form? A. 2,350 B. 0.0235 C. 0.000235 D. 2,350,000

  38. Click here Slide 22 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. YES !!! Remember, if you are confused – start somewhere! See if you can begin with a small part of the problem first!

  40. 10.) What number is represented on the mat shown below? The shaded counters represent negative numbers and the white counters represent positive numbers. B. 12 A. 18 D. -12 • -6

  41. Try to create some “visual tricks” to help you remember what to do for some problems… When you see two-colored counters, think of one negative and one positive going together to make a “zero sandwich”! 0 Slide 49 Click here

  42. YES !!! “Visual tricks” can sometimes help you remember what to do! Try to create some of your own “visual” tricks.

  43. 11. Which statement is true? A. -7 > -1.5 B. - 2/3 > - 1/3 C. -2.4 < - 2.46 D. – ½<- 0.2

  44. 1 4 3 -4 -3 -2 2 0 -1 Negative numbers can be very confusing – don’t JUMP at an answer – THINK before you write – DRAW a number line! Remember that numbers get smaller as you go left on the number line! Slide 44 Click here

  45. YES !!! Don’t JUMP at an answer – THINK before you write!

  46. 12. Susan bought fencing for a rectangular garden that measures 12 feet by 10 feet. After she bought the fencing, she decided to increase the dimensions of the garden to 18 by 12 feet. If she wants to install fencing around the new garden, how much more fencing does she need? B. 16 feet • 8 feet D. 104 feet C. 96 feet

  47. 12 ft 10 ft 12 ft 18 ft Sometimes, if you do not understand a problem, drawing a picture of what is happening will help! Start drawing and labeling the gardens… Slide 48 Click here
