SPACE SHOOTERS
Part I
 Objective : Use of protractor and
mathematical relationship of angles
 Relay your secret message to the fellow
spaceman while avoiding meteors and aliens.
 Use your laser to identify the correct path.
Part I
Problems:
 Multiple choice
 Using protractor measure angles.
 Properly line up protractor to vertex of angle
 Properly read measurement of angle on protractor
 Mathematically, if an angle is 30 degrees, it is
complementary to what angle? 60 degrees
 Is the angle acute or obtuse?
 If an angle is 70 degrees, it is supplementary to
what angle? 110 degrees
 Is the angle acute or obtuse?
Part II
 Objective : Sample space, Probability,
Percent/fractions
 Man , my laser is broken, this means I have to
deliver the message myself! The problem,
every couple of hundred of thousands of
miles I have to pay a toll and…I’m cheap!
Part II
Problems:
 I have a bag of coins for the toll: 1 penny, 2
quarters, 3 nickels and 4 dimes.
 What is the sample space? 10
 What is the probability the first coin I choose
is a penny from the bag? 1/10
 Change this fraction to a decimal? 0.10
 Can you change that to percent? 10%
