Name_________________________ 05/11/15 Testing dates: May 21 & 22 Here is a review sheet for the 4th grade SOL test. You can also download this from my website if you’d like to be able to just click on the links. TEI Questions! Please try this first!! http://www.allenteachers.com/interactive/mathematics/grade-4/ **In my opinion, the math test challenges your child’s perseverance, especially with its two and threestep word problems. Most of the 4th graders this year have done an excellent job of taking the nine weeks’ assessment tests very seriously; please remind your child of how hard he or she has worked already, as I will in class. I know they can make it through! (I am very proud of them!) Please have your child practice multiplying, dividing, adding, and subtracting whole numbers, and adding and subtracting fractions and decimals. You can quiz your child on the vast amount of vocabulary there is for geometry by making flash cards, or letting them write on something fun like shaving cream, etc. You can also go to quizlet.com, where there are some online quizzes/flashcards for many of our objectives: *http://quizlet.com/6349494/parallel-intersecting-perpendicular-lines-flash-cards/ *http://quizlet.com/8927712/bradleys-math-line-ray-segment-flash-cards/ *http://quizlet.com/6965986/math-vocabulary-sol-44-flash-cards/ *http://quizlet.com/10191963/us-customary-units-flash-cards/ (1 cup=8 ounces needs to be ignored; we only focus on 16 ounces = 1 pound) I. Number and number sense: 4.1, 4.2, 4.3 (place value, identifying, ordering, and equalizing fractions and decimals) 4.1 & 4.2: Sing this song to remember place value from ones to millions, and tenths to thousandths: ones, tens, hundreds, thousands, ten thousands, hundreds thousands, one million and if it's to the right of the decimal, tenths, hundredths, thousandths! http://www.thatquiz.org/tq-c/math/place-value/ PLEASE click all (under place value) and both (integer and decimal) Rounding tips: 4 or less, let it rest 5 or more, let it score Place value rounding game: http://www.funbrain.com/tens/index.html **When you round to the nearest whole number, round to the ONES place: 56.87=57 Ordering whole numbers: When deciding if a number is greater than >, less than <, or equal to =, line up the numbers by the ones place. Who is bigger? Also, remember that 3 < 4…the sign points to the smaller number. The larger number is being eaten. http://www.thatquiz.org/tq-8/math/inequality/ Ordering fractions: cross multiplying: Example: ½ ¾ 2 is multiplied by 3 to get 6, and 1 is multiplied by 4 to get 4. 6 is greater than 4, so ¾ is greater than ½. Also, here are fractions on a number line: http://www.mathsisfun.com/numbers/fractions-match-frac-line.html 4.3: equalizing fractions and decimals: *Remember, think of quarters when you think of 4ths; your hand when you think of 5ths (20, 40, 60, 80, 100); ½ = 50 cents **Look for the $100 man/picture included in this packet. *Great resource for all things fractions: http://www.huneycutt.biz/math35/math35.html scroll down to this section: D. Fractions (in order of difficulty) Good resource for all things decimal: http://www.primaryresources.co.uk/maths/mathsB6b.htm *Identify the division statement that represents a fraction: ¼ means 1 divided by 4 II.

A factor is simply a number that is multiplied to get a product Here are lists of all the factors of 16, 20, and 45. 16 --> 1, 2, 4, 8, 16 20 --> 1, 2, 4, 5, 10, 20 45 --> 1, 3, 5, 9, 15, 45 The GCF of all 3 would be ?? 1! **Also, here’s a website that explains adding and subtracting fractions with unlike denominators: http://www.coolmath4kids.com/fractions/fractions-12-adding-subtracting-different-denominators01.html *Use this Quia quiz to practice greatest common factor, simplify fractions, least common multiple, and divisibility rules [Who Wants to be a Millionaire format] : http://www.quia.com/rr/5151.html III. Measurement: 4.6, 4.7, 4.8, 4.9 (weight/mass, length, liquid volume, elapsed time) Pictures to help students understand weight better: 1,000 grams= 1 kilogram 1 ounce = OR 1 ounce 1 gram = 1,000 grams = 1 Kilogram 16 ounces= 1 pound 2,000 pounds = 1 ton 1 nickel = 5 grams (Think: 5 cents = 5 grams) 4.7 interactive measuring with a ruler : http://www.harcourtschool.com/activity/elab2002/grade_4/016.html http://www.thatquiz.org/tq-9/math/measurement/ An inch (in.) is about the length of your thumb from the first knuckle to the tip. A foot (ft) is about the length of a sheet of paper. Smaller objects, such as pencils or nails, are measured in inches. A yard (yd) is about the length of a baseball bat. A yard is equal to three feet. The length of a football field is measured in yards. A millimeter (mm) is about the thickness of a dime. A person’s height or the length of a room is measured in feet. A mile (mi) is about the distance you can walk in 20 minutes. The distance a person travels in a car is measured in miles. A centimeter (cm) is about the A meter (m) is about the width width of your index finger. of a door. 4.8 There was a Garden; 4 Queens walked inside; each queen has a Prince and a Princess; each P had two Children: 1 gallon is made of 4 quarts; each quart is made of 2 pints; each pint is made of 2 cups. To convert measurement units: 1) Look at the units in the problem and write what you know. Ex.: 4 yards = ____ feet I know that 3 feet = 1 yard 2) Put an S under the smallest unit, and a L under the largest unit. Ex.: 3 yards = ____ feet L S 3) If a blank is in front of the S, write an X. If a blank is in front of the L, write a . 4) Divide or multiply the numbers that you know. Ex.: 4 yards = ____ feet I know that 3 feet = 1 yard 4 x 3 = 12, so 4 yards = 12 feet 4.9: elapsed time Matching digital time to analog time: http://www.harcourtschool.com/activity/con_math/g03c05.html when you go to this site, click the “time passed” on the left hand side: http://www.thatquiz.org/tq-g/math/time/ Strategy: Students write a t-chart, and first figure out the hours, and then the minutes. I encourage them to draw a clock to figure out the minutes. Example: How much time will elapse between 2:15 pm and 5:33 pm? 3:15 4:15 5:15 1 hr 1 hr 1 hr 5:15-5:20 5:20-5:25 5:25-5:30 5:30-5:33 5 min 5 min 5 min 3 min Answer: 3 hours and 18 minutes elapsed time interactive: http://www.harcourtschool.com/activity/elab2002/grade_3/018.html or http://www.quia.com/mc/66516.html IV. Geometry: 4.10, 4.11, 4.12 (points, lines, etc.; transformations, & polygons) 4.10: basic terms for lines, line segments, parallel lines, perpendicular lines, etc. http://www.mathleague.com/help/geometry/basicterms.htm#rays Lots of vocabulary to remember!! •A point is a location in space. It has no length, width, or height. A point is usually named with a capital letter. * A line is a collection of points going on and on infinitely in both directions. It has no endpoints. When a line is drawn, at least two points on it can be marked and given capital letter names. Arrows must be drawn to show that the line goes on in both directions infinitely (e.g., , read as “the line AB”). AB * A line segment is part of a line. It has two endpoints and includes all the points between those endpoints. To name a line segment, name the endpoints (e.g., , read as “the line segment AB”). AB * A ray is part of a line. It has one endpoint and continues infinitely in one direction. To name a ray, say the name of its endpoint first and then say the name of one other point on the ray (e.g., , read as “the ray AB”). AB * Two rays that have the same endpoint form an angle. This endpoint is called the vertex. Angles are found wherever lines and line segments intersect. An angle can be named in three different ways by using – three letters to name, in this order, a point on one ray, the vertex, and a point on the other – one letter at the vertex; or – a number written inside the rays of the angle. * Intersecting lines have one point in common. *Perpendicular lines are special intersecting lines that form right angles where they intersect. * Parallel lines are lines that lie in the same place and do not intersect. Parallel lines are always the same distance apart and do not share any points. 4.11: Practice activities can be found by clicking on the following link: http://www.harcourtschool.com/activity/icy_slides_flips_turns/ Again, lots of vocabulary!! Practice activities can be found by clicking on the following links: 4.11 *In order to help students remember terms from last year, point out that reflection has a fl for flip; translation has a sl for slide. * Congruent figures are figures having exactly the same size and shape. Opportunities for exploring figures that are congruent and/or noncongruent can best be accomplished by using physical models. * A translation is a transformation in which an image is formed by moving every point on a figure the same distance in the same direction. * A reflection is a transformation in which a figure is flipped over a line called the line of reflection. All corresponding points in the image and preimage are equidistant from the line of reflection. * A rotation is a transformation in which an image is formed by turning its preimage about a point. * The resulting figure of a translation, reflection, or rotation is congruent to the original figure. A polygon is a closed plane geometric figure composed of at least three line segments that do not cross. None of the sides are curved. on with three angles and three sides. pair of parallel sides. parallel. -sided polygon. -sided polygon. -sided polygon. -sided polygon. -sided polygon. -sided polygon. interactive quadrilaterals: http://www.mathsisfun.com/geometry/quadrilaterals-interactive.html When you go here, click on all of the shapes on the left hand side that you want to use: http://www.thatquiz.org/tq-f/math/shapes/ Quadrilateral quest—challenging! http://teams.lacoe.edu/documentation/classrooms/amy/geometry/68/activities/quad_quest/quad_quest.html V.
