Agenda for today • Welcome • Important background skills • Tour of library, bookstore • New topic: Plane • New topic: Point • New topic: Line
Welcome • Registration list • Syllabus • Daily routine • Your questions about the course • A little about you • Course overview
A Little about You • 2 things: print your name and put your logo (or signature) • ‘Anything you’d like me to know? • ‘Any concerns (about math, etc.)?
A Little more about You • What do you want to do in the long-term for moolah? • Optional, but helpful to me: • What is your home school? • What electives are you in? • What are some hobbies/interests?
Overview of Geometry Plane Point Line Angle Flat (2-D) Shapes Solids (3-D)
Important Math Skills • Recall of multiplication facts • Operating on fractions • Solving an algebra equation • Using the “order of operations”
8) "I've got these covered…" • (Multiplication facts) • (Working with fractions) • (Solving equations) • (Doing operations in right order)
Solve an Equation… • Isolate the “variable term” • Divide both sides by the variable’s coefficient • Check your solution What you change on one side, Change also to the other
The Order of Operations… • Grouping symbols • Exponents and roots • Multiplication and division • Addition and subtraction
Important Study Skill • Taking notes
Tour of Campus • Bookstore • Supplies • Snacks • Library • Photocopier • Free printing (PowerPoint slides) • Coffee Shop
Topic: Plane • Is the flat “field of play” for anything 2-D • Can be labeled as a coordinate plane
Plane (continued) • How many planes are present in the surfaces of this solid?
Plane (continued) • How many planes are present in the surfaces of this solid?
Plane TASKS • Draw a neat coordinate plane • Label the axes (X and Y) • If given a labeled coordinate plane, interpret the scale Complete the FIRST PROBLEM SET*
*Problem Sets • These will be completed during class. (I will give points for the day’s problem set before you leave each day, and each day’s assignment is worth 3% of your final grade) • This is a time to get help!
Topic: Point • Is a location somewhere in the plane • Is pretty unimportant when alone; but when you connect it with another, you start making other stuff • Can represent meaningful data
Point (continued) • Is also known as a coordinate • Has a location described by two #s one for its location on the X axis one for its location on the Y axis • Looks like this: (#, #)
Demo: Points as Data Let X represents time Let Y represent distance
PointTASKS • If given a coordinate, find and draw (“plot”) the point For example, draw the point (-5, 7) • If shown a point in the coordinate plane, write the coordinate Complete the SECOND PROBLEM SET
Break time again… • Entertainment options: Puaattacks -OR- (Mystery Box)
Topic: Line • Is straight and goes on forever! • Passes through a lot of points • Has distance or length • Can you think of anything that is actually a true line in reality?
Line (continued) • Is related to a ray • Is also related to a line segment
Line (continued) • Which do you see here?
Line (continued) • Which do you see here? Complete the THIRD PROBLEM SET
Line (continued) • In the coordinate plane, it… is described by two traits slope (rise/run) y-intercept has an equation y=mx+b
Line TASKS • Identify lines, rays, and segments • If given a line on a coordinate plane, find its equation • If given an equation, draw the line it describes Complete the FOURTH PROBLEM SET
For the rest of the time… • Complete the FIFTH PROBLEM SET • Complete the SIXTH PROBLEM SET • Show me when you’re done and I will check today’s assignment • Fill-in your check-in sheet for today
Daily Check-in Sheets • I want to know how confident you feel about each topic before you leave for the day • I will respond to your questions next class
Today's tunes • Salif Keita - La différence • Metallica – Call of Ktulu • Edward Weiss – Ocean Piano
