1. Copy this chart on your cover page Ballpark Conversions Inch= about 2.5 centimeters or 25 millimeters Yard= almost a meter (meter is about 40 inches, a yard is 36 inches) Mile= about 1.5 kilometers (miles are about 1.5 times longer than kilometers) Ounce= about 28 grams Quart= about the same as a liter Pound= about 2 kilograms (if you weigh 100 pounds, then you weigh 50 kilograms) 6.9 The student will make ballpark comparisons between measurements in the U.S. Customary System of measurement and measurements in the metric system. a) length — part of an inch (1/2, 1/4, and 1/8), inches, feet, yards, miles, millimeters, centimeters, meters, and kilometers; b) weight/mass — ounces, pounds, tons, grams, and kilograms; c) liquid volume — cups, pints, quarts, gallons, milliliters, and liters; and d) area — square units. *

2. 6.9 Vocabulary (handout given to students) Capacity - A measure of the ability to receive, hold, or absorb volume. Length - A measure used as a unit to estimate distances. Weight - Weightis determined by the pull of gravity on the mass of an object.The weight of an object changes dependent on the gravitational pull at its location. Mass - Mass is the amount of matter in an object. The mass of an object remains the same regardless of its location. In everyday life, most people are actually interested in determining an object’s mass, although they use the term weight, as shown by the questions: “How much does it weigh?” versus “What is its mass?” Volume –The amount of space that a three dimensional figure contains. Volume is expressed in cubic units, it tells you the number of cubes of a given size are used to fill the figure. Area – The product of the length and the width (A = lw). The area of a triangle is one half of the measure of the base times the height: A = bh, or A = bh ÷ 2. Square Unit – Units used when measuring the area of a two-dimensional figure. U.S. Customary System –System of measurements using inch, foot, yard, mile, fluid ounce, cup, pint, quart, gallon, dry ounce, pound, and ton. Inch –measurement, about the width of a quarter Foot –used to measure length, equal to 12 inches. Yard –3 feet, approximate distance from nose to fingertip for the average adult Mile –used to measure distance, equal to 1,760 yards Ounce (oz) – measurement for liquids or solids; (p. 470) fluid ounce (fl oz), about 2 tablespoons of water; dry ounce (oz), about the weight of a pencil Pound (lb) –used to measure mass, 1 pound = 16 ounces, 1 package of notebook paper Ton (T) –solid measurement, 1 ton = 2,000 pounds, average passenger car Cup (c) –liquid measurement, 1 cup = 8 fluid ounces, coffee cup Pint (pt) –liquid measurement, 1 pint = 2 cups, small ice cream container Quart (qt) –liquid measurement, 1 quart = 2 pints, small plastic jug of milk Gallon (gal) –liquid measurement, 1 gallon = 4 quarts, large plastic jug of milk Metric System –A decimal system of units based on the meter as a unit length, the gram as a unit mass, and the liter as a unit of volume. Meter (m) –basic unit of length in the metric measurement system, equivalent to 39.37 inches or just more than 3 feet. Centimeter (cm) –metric measurement, 2.5 centimeters = to 1 inch, half the width of a penny Kilometer (km) –metric measurement for distances, 6.2 km = to 1 mile, six city blocks Millimeter (mm) –length measurement, 25 millimeters = 1 inch, thickness of a dime Liter (L) –liquid metric measure, 1 liter = 1 quart, 1 small pitcher Milliliter (ml) –liquid metric measurement, 1 milliliter = 0.03 fl oz, an eyedropper Gram (g) – metric measurement for solids, a paper clip Kilogram (kg) –solid metric measure, 1 kilograms = 2 pounds, six medium apples Milligram (mg) –A metric unit of mass. One Milligram equals one-thousandth of a gram. A grain of sand standard unit The measurement of the mass, length, or volume of an object using either the Customary System or the Metric System nonstandard unit Used to estimate the mass, length, or volume of an object using a comparative unit temperature water freezes 0° C and 32°F temperature water boils 100°C and 212°F normal body temperature About 37°C and 98°F

5. 6.9 Non-Standard (handout given to students)Sometimes you will be asked to measure with something that is not a ruler, for example, a crayon, a pencil, your hand, and so on. You should use the line tool on computer tests or paper on paper tests to make your own ruler to measure with. Here are some examples.How many lady bugs are the same height as the flower? Make your own ruler the same height as me! Ladybug ruler
