  1. PASS REVIEW 3rd Grade Math Review

  2. POLYGONS • A polygon is a plane figure that is closed with thee or more line segments. • Polygons are classified based on the number of sides and angles they have.

  3. Lines, Line Segments, and Rays A line extends forever in both directions. A line goes on forever and ever. A line segment is part of a line. It has two end points. A ray extends forever in only one direction. It has one end point.

  4. Types of Lines

  5. Angles

  6. Flips, Slides, and Turns Does this picture show a flip, slide, or turn?

  7. Circles Circumferenceis the distance around the circle. Diameteris the line segment that passes through the center point of the circle and touches each side of the circle. Radiusis a line segment that runs from the center point of the circle and extends to the outer edge of the circle. Thecenterof the circle is the middle.

  8. PerimeterPerimeter is the distance around the outside of a polygon. What is the perimeter of this scalenetriangle? What is the perimeter of this rectangle? What is the perimeter of this square? What is the perimeter of this equilateral triangle? Perimeter Practice

  9. Place Value Find the place value of the underlined digit. 1.) 234 4.) 432,894 2.) 4,098 5.) 87 3.) 52,327 6.) 9,769

  10. Let’s Practice Place Value! Place Value (Models) Place Value (Names) Place Value (Value)

  11. Rounding Rounding a number is when you take a number and "bump it up" or "bump it down" to a nearby and "cleaner" number. A number can be rounded to any place value you want.

  12. RoundingRhyme Find your place. Look next door. Five or greater Add one more. All digits in front Stay the same. All digits behind, Zeros your name!

  13. Let’s Practice Rounding! Rounding Game

  14. FRACTIONS A fraction is a part of a whole. Example:If I eat 1 piece of the whole pizza that was cut into 8 equal slices, I would have eaten 1/8 of the pizza. Click here for practice!

  15. Mixed Numbers A fraction that is greater than one is written as a mixed number. A mixed number consists of both a whole number and a fraction! Here is a picture of 1 whole pizza a half of another pizza. The mixed number is 1 ½ .

  16. Practice Mixed Numbers! In your journal, write the mixed number that each picture illustrates.

  17. Odd and Even Numbers An ODD number ends in 1, 3, 5, 7, or 9. An EVEN number ends in 0, 2, 4, 6, or 8. No matter how big or small the number, always look at the last digit (the ones place) to determine if the number is even or odd.

  18. Odd and Even Numbers in Addition Two even numbers added together willALWAYSresult in an even answer! 6 + 6 = 12 56 + 4 = 60 Two odd numbers added together will ALWAYS result in an even answer! 5 + 3 = 8 33 + 15 = 48 One even and one odd number added together will ALWAYS result in an odd answer. 4 + 3 = 7 76 + 21 = 97

  19. Odd and Even Numbers in Subtraction Two even numbers will ALWAYSresult in an even answer when subtracted from each other! 6 - 4 = 2 56 - 4 = 52 Two odd numbers will ALWAYS result in an even answer when subtracted from each other! 5 - 3 = 2 33 -15 = 18 One even and one odd number will ALWAYS result in an odd answer when subtracted from each other. 4 - 3 = 1 76 - 21 = 45

  20. Odd and Even Numbers in Multiplication Two even numbers multiplied together willALWAYSresult in an even answer! 6 x 6 = 36 12 x 4 = 48 Two odd numbers multiplied together will ALWAYS result in an odd answer! 5 x 3 = 15 11 x 7 = 77 One even and one odd number multiplied together will ALWAYS result in an even answer. 4 x 3 = 12 5 x 10 = 50

  21. Odd and Even Numbers What do you remember? • If I add two even numbers together, will my solution be odd or even? • If I multiply an odd number and an even number, will my solution be odd or even? • If I subtract two odd numbers, will my solution be odd or even? • If I add and even an odd number together, will my solution be even or odd?

  22. Measurement

  23. MeasurementCustomary Units Oil for your car comes in a quart-sized container. A small cup of coffee holds approximately 1 cup. Each of these medicine cups holds 1 fluid ounce of medicine. This milk jug holds 1 gallon of milk.

  24. Measurement Comparing Units Miles and kilometers used when measuring distance. A kilometer is about one-half of a mile. A meter is slightly more than a yard. As you can see here, the yard stick and meter stick are similar to one another. The water bottle is equal to one liter and the chocolate milk bottle is equal to one quart. A liter is slightly more than a quart. liter quart

  25. Measurement Comparing Units A paper clip has a mass of approximately one gram. There are approximately 28 grams in one ounce. Ounces and grams are similar units. A tennis shoe has a mass of approximately one kilogram. A kilogram is slightly more than two pounds.

  26. 1.) A centimeter is about the same as a. one finger width b. width of someone’s wrist c. length of a desk 2.) A fluid ounce is about the same as a. cup of apple juice b. amount a bathtub holds c. two tablespoons 3.) An inch is about the same as a. width of someone’s knee b. length of someone’s knuckle c. height of a chair 4.) A pint is about the same as a. 16 ounce coke b. gallon of milk c. length of a yardstick 5.) A foot is about the same as a. Length from an elbow to someone’s wrist b. Length of a classroom c. How much a scale can hold 6.) A yard is about the same as a. width of a pencil b. height from the floor to someone’s hip c. the distance from school to McDonalds 7.) A liter is about the same as a. amount a swimming pool holds b. one teaspoon c. half of a two liter coke 8.) A meter is about the same as a. half the height of a normal size door b. width of a school gym c. amount a coffee cup holds 9.) An ounce is about the same as a. weight of a baby b. lenth of a classroom c. a single strawberry 10.) A pound is about the same as a. a bundle of bananas b. the distance from Charlotte to Atlanta c. three paper clips Let’s TEST your measurement KNOWLEDGE!

  27. Dot Plots / Line Plots Practice Dot Plots!

  28. Bar Graphs Practice Bar Graphs!

  29. Pictographs Practice Pictographs!

  30. Tables Practice Interpreting Data in Tables!

  31. Finding Range Find the range of the following data sets in your math journal. 1.) 4, 9, 0, 2, 2, 3, 8, 4 2.) 39, 10, 29, 23, 42 3.) 189, 187 , 156, 204

  32. Range Range – The range of a set of data determines how spread out the data is. In order to find the range, you simply follow 2 very simple steps! Steps: 1.) Order the numbers from Least to Greatest. 2.) Take the greatest number and subtract the smallest number. Your answer equals the RANGE! Greatest Number - Smallest Number Range

  33. Probability Likely, Unlikely, Certain, Impossible Practice Probability

  34. Decomposing Numbers 367 The number 367 can be decomposed or broken up into smaller parts! It would look like this: 300 + 60 + 7

  35. Decomposing Numbers Decompose the following numbers in your math journal. 1.) 78 2.) 675 3.) 2,029 4.) 12,098 5.) 198,334

  36. Patterns Practice Patterns
