WOES Fifth Grade • A benchmark is a familiar number used as a point of reference. You can use a benchmark to determine a reasonable estimate. • If one piece of candy corn is: Height: Weight: Length: • Remember your base 10 rules: n x 1= 1, n x 10= 10, n x 100= 100 in. oz. in. cm. kg. cm. 1 foot (ft. or ') 1 yard (yd.) = 12 inches (in. or ") = 36 inches (in.) Measures of Length 1 yard (yd.) = 3 feet (ft.) 1 mile (mi.) = 5,280 feet (ft.) 1 mile (mi.) = 1,760 yards (yd.) 1 kilometer = 1,000 meters 1 meter = 100 centimeters 1 centimeter = 10 millimeters • Standard: http://www.rsinnovative.com/rulergame/ • Metric: http://www.askmrcscience.net/sitebuildercon tent/sitebuilderfiles/readingametricruler.pdf 1. 2. 3. 4. 5. How many centimeters long is 1 candy corn? How many cm. long are 10 candy corns? How many cm. long is 100 candy corns? How many candy corns are needed to reach 6 in.? Estimate the length of all of your candy corns in cm. and in inches. 6. What is the actual length of all of your candy corns in cm. and in in.? 16 1 pound = ounces (lb.) (oz.) 1 ton (T.) 2,000 = pounds (lb.) 1 milligram = 0.001 gram 1 centigram = 0.01 gram 1 decigram = 0.1 gram 1 kilogram = 1000 grams 1. What is the weight of 10 candy corns in grams? 2. How many candy corns would equal 1 kilogram? 3. If each candy corn costs $0.02, what would be the cost of one kilogram? 4. If each candy corn costs $0.02, what would be the cost of 200 grams? 1 cup (c.)= 8 fluid ounces (fl. oz.) 1 pint (pt.)= 2 cups (c.) 1 quart (qt.)= 4 cups (c.) 1 quart (qt.)= 2 pints (pt.) 1 gallon (gal.)= 4 quarts (qt.) 1-1/2 tsp.= 1/2 tbsp. 3 tsp. = 1 tbsp. 2 tbsp. =1/8 cup 4 tbsp. =1/4 cup 8 tbsp. =1/2 cup 16 tbsp. = 1 cup 1. How many candy corns will fit in a teaspoon? 2. How many candy corns will fit in a tablespoon? 3. How many candy corns will fit into a cup? 4. How many candy corns will fit into a pint? 5. How many candy corns will fit into a quart? 6. How many candy corns will fit into a gallon? Range refers to the distance “Between”. The Range refers to the distance between the highest and lowest value within a set of numbers. Strategy: Order your data from greatest to least. Mean means “Average”. Mean = the average of a group of numbers. Strategy: Add all numbers then divide by the number of entries. Median means is in the “Middle”. Strategy: Order the numbers from least to greatest. Mode represents the most “Popular” The Mode is the number that appears the most frequently within a set of number. Strategy: What number do you see the most often? 1. Time each member of your group to find out how long it takes to eat one candy corn. DO NOT RUSH! Record your answers in minutes and seconds. 2. Find the range of the times. 3. Find the median of the times. 4. Find the mode of the times, if there is one. 5. Find the mean of the times. 6. Make a stem and leaf plot to represent your data. The top number the Numerator, it is the number of parts you have. The bottom number the Denominator, it is the number of parts the whole is divided into. Hint: Denominator- “down”-ominator 1. 2. Divide the candy corns into two equal groups. What is ½ of the total number? Divide the candy corn into four groups. How many are in each: a. b. c. 3. How many are in 2/4 ? How many are in ¾ ? How many are in 4/4 ? Divide the candy corns into sixths. a. What does 1/6 equal? b. What does 2/6 equal? c. What does 3/6 equal? d. What does 4/6 equal? e. What does 5/6 equal? f. What does 6/6 equal? 4. What fractional parts had the same number of candy corns? 1. 2. 3. 4. 5. addition subtraction multiplication division inequality
