Chapter 22: Measurement Customary measurement of length, mass and volume Metric measurement of length, mass and volume Customary Measurements A system of measurement used in the United States used to describe how long, how heavy, or how big something is Examples: inches, feet, yards, miles Customary Measurement of length 12 inches = 1 foot 3 feet = 1 yard 36 inches = 1 yard 5,280 feet = 1 mile Customary Measurements of weight/mass 16 ounces (0z) = 1 pound (lb) 2000 pounds (lbs) = 1 ton (T) Customary Measurement of Capacity/ Volume Capacity/volume: how much a container can hold 8 fl oz = 1 cup 2 cups = 1 pint 2 pints = 1 quart 2 quarts = 1/2 gallon 4 quarts = 1 gallon Metric Measurements A system of measurement used in most other countries to measure how long, how heavy, or how big something is Metric Measurements of Length 10 millimeters (mm) = 1 centimeter (cm) 100 centimeters = 1 meter (m) 1,000 meters = 1 kilometer (km) Metric Measurements of Weight/Mass 1,000 milligrams (mg) = 1 gram (g) 1,000 grams = 1 kilogram (kg) Metric Measurements of Capacity/ Volume The milliliter (mL) is a metric unit used to measure the capacities of small containers. Example= a dropper The liter (L) is equal to 1,000 mL, so it is used to measure the capacities of larger containers. Example= a bottle of soda Remember… King Henry’s Daffy Uncle Drinks Choc Milk *This can help you with conversions……… Next chapter… Chapter 23: Geometry Quadrilaterals, Plotting coordinates on a grid Perimeter and Area Volume of rectangular prisms Quadrilaterals Quadrilaterals are any four-sided shapes. They must have straight lines and be two-dimensional. Examples: squares, rectangles, rhombuses, parallelograms, trapezoids, kites More about quadrilaterals The Square The square has four equal sides. All angles of a square equal 90 degrees. The Rectangle The Rectangle has four right angles and two sets of parallel lines. Not all sides are equal to each other. The Rhombus A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. A rhombus is sometimes called a diamond. The Parallelogram A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal. Plotting Coordinates Plotting Coordinates (continued) (x,y) Find the point on the x-axis first (horizontal / left to right) Then find the point on the y-axis and graph (vertical / up and down) Finding the Perimeter To find the perimeter of most two-dimensional shapes, just add up the sides Area Area is the measurement of a shape’s surface. Remember that units are squared for area!! Finding the Area of a Square To find the area of a square, multiply the length times the width A= (l)(w) A=2x2 A = 4 cm² Finding the area of rectangles To find the area of a rectangle, just multiply the length and the width. A= (l)(w) Volume Volume is the amount of space that a substance or object occupies, or that is enclosed within a container Remember that the units of volume are cubed (example: inches^3) because it measures the capacity of a 3-dimensional figure! Finding the Volume of Rectangular Prisms To find the volume of a rectangular prism, multiply the length by the width and by the height of the figure V = (l)(w)(h) V=6x3x4 V = 72 cm³ Practice, Practice, Practice!
