8 fl oz = 1 c 2 pt = 1 qt 16 c = 1 gal 1 pt = 2 c 1 gal = 4 qt 20 qt = 5 gal King Hector Died Monday Drinking Chocolate Milk (kilo, hecto, deka, Base Unit: meter, gram, Liter, Deci, Centi, Milli) ___ fl oz = 1 c___ pt = 1 qt___ c = 1 gal___ qt = 5 gal1 pt = ___ c1 gal = ___ qt 1 gal = 128 fl oz 1 gal = ___ fl oz What is the saying (mnemonic device) for the metric prefixes?
Kilo Meter, Gram, Liter Smaller (you divide) Milli Larger (you multiply) 0.25 cm (move decimal one place to the left) (divide by 10) 1,200 g (move the decimal 3 places to the right) (multiply by 1,000 ) 2,000 mL (move decimal 3 places right) (multiply by 1,000) What is the largest metric prefix? What is the smallest metric prefix? What are the 3 base units for metric? If you are converting from a smaller unit of measurement to a larger unit of measurement, will your answer be smaller or larger? 1.2 kg = ___ g2 L = ___ mL 2.5 mm = ___ cm If you are converting from a larger unit of measurement to a smaller unit of measurement, will your answer be smaller or larger?
2,000,000 mm (move decimal 6 places right) (multiply by 1,000,000) 2.5 cm Slightly longer than a yard 30 cm 40 in. (between 39 & 40 in.) 1.5 kmHalf a mile 0.5 kg (move the decimal 3 places left) (divide by 1,000) ___ mm = 2 km 1 km is slightly farther than ___ mi. 1 mile is slightly farther than ___ km. 1 meter ≈ ___ in.___ cm ≈ 1 in. 1 ft ≈ ___ cm 500 g = ___ kg Is a meter longer or smaller than a yard?
28 g 2 pounds 0 o C and 32 o F 1 Liter 1 quart 100 o C and 212 o F 37 o C and 98 o F 5 grams 1 oz ≈ ___ g 1 kg is a little more than ___ lb 1 qt is a little less than ___ L Water freezes at ___ C and ___ F 1 L is a little more than ___ qt Water boils at ___ C and ___ F Normal body temperature is about ___ C and ___ F 1 nickel ≈ ___ g
20o C and 70o F Weight Paper clip Area of a rectangle or parallelogram (technically also a square) 5 Liters (move the decimal 3 places left) (divide by 1,000) 5 costumes8 gallons Mass Room temperature is about ___ C and ___ F Weight or Mass? Determined by the pull of gravity on the mass of an object. Weight or Mass? Amount of matter in an object. 1 gram (g) is about the weight of 1 small ___? If you need 7 ¾ gal of juice, how many gallons would you buy? 5000 mL = ___ L If you have enough material to make 5 ¼ costumes, how many costumes can you actually make? A = lw Is the formula for what?
Perimeter Add up all of the sides Area of a triangle Area of a square 8 in. (must be perpendicular to the base) Side of a squareDivide by two Perimeter of a square What is the measure of the distance around a polygon called? In the formula A = s 2, “s” stands for what? In the formula A =1/2 bh, what do you actually do with multiplying by 1/2? A = ½bh Is the formula to find what? How do you find the perimeter of any object? A = s 2 Is the formula to find what? P = 4s Is the formula to find what? In the following triangle which is the height? 10 in 7 in 8 in.
Find the area A = lw A = 10 x 15 A = 150 ft2 Find the perimeter P= P = 60 About 5 doors 1 way: Find the length and width of the whole figure: 16 cm high and 12 cm wide Then find the area of a rectangle A=lw A = 16 x 12 = 192 cm2 Or 2nd way: Find the area of one small square and then multiply by the number of squares that make up the figure. A=s2 A= 42 = 16 cm2 then 16 x 12 = 192 cm2 About 2 ½ windows (closer to 3 windows) (Pi) Approx or 22/ or 22/7 Find the perimeter of a rectangle P = P = 36 in. How much carpet will you need for a rectangular room in your house that measures 10 ft x 15 ft? You have an equilateral triangular garden that needs fencing, how much fencing will you need if one side measures 20 ft? You want to decorate a frame with ribbon, how much ribbon would you need if the frame measures 8 in by 10 in? What is the ratio of the circumference and the diameter of any given circle? What is the approximate value of ? About how many doors would equal the length of the wall? What is the area of the whole figure? 4 cm About how many windows would equal the length of the wall?
Circumference of a circle radius ft 2 Area of a circle 6.28 ft protractorAcute angle Diameter (d) What is the tool called that is used for measuring angles? What is half of the diameter called? C= 2 r What is this formula used to find? What is the name of an angle that measures between 0 o and 90 o ? What is the circumference of a circle if the diameter is 2 ft? (C =2 r) A = r 2 Is the formula to find what? What is 2r = ___? What is the area of the following circle? (A = r 2 ) 8 ft
Obtuse angle Acute triangle Obtuse triangle Right triangle False (if you have 2 right angles than that equals 180o so therefore there is no degrees left for the 3rd angle since the sum of the 3 angles of a triangle are to equal 180 o) False (since the sum of the 3 angles of any triangle equals 180 therefore only one angle can be more than 90 o ) 45 o angle Right angle True or False? A triangle can have more than one obtuse angle? What type of triangle has one obtuse angle and two acute angles? What type of triangle has three acute angles? What is the name of an angle that measures between 90 o and 180 o ? What angle is half of a right angle? True or False? A triangle can have more than one right angle?
