2 Registration list Syllabus and supply list A little about you Daily routine On-line access to PowerPoint files Your questions about the course

3 Several pencils, a sharpener, and an eraser Markers (at least 3 of different colors) Ruler (6-inch is fine) Protractor (a half-circle for angle measure) Paper (regular, ruled paper in a spiral notebook is fine) Folder (or binder) devoted only to Geometry Scientific calculator (if yours is a graphing calculator, that is fine)

4 2 things: print your name and put your logo (or signature) What are 3 things you’d rather be doing this summer (disregarding time and transportation) ‘Anything you’d like me to know? ‘Any concerns (about math, etc.)?

5 PlanePoint LineAngle Flat (2-D) Shapes Solids (3-D)

6

7 Products of small numbers Steps for solving Steps for evaluating

8 1. Simplify both sides 2. Isolate the “variable term” 3. Divide both sides by the variable’s coefficient 4. Check your solution

9

10 1. Grouping symbols 2. Exponents and roots 3. Multiplication and division 4. Addition and subtraction

11

12 Taking notes TOPIC: Line VocabularySymbolsTask Line Ray Segment Equation for a line Slope (rise/run) Y-intercept y=mx+b m b Identify it Come up with it (requires two things: slope, y-intercept) Find it (divide the line’s rise by its run) Find it (look where the line crosses the y-axis)

13 Is the flat “field of play” for anything 2-D Can be labeled as a coordinate plane

14 How many planes are present in the surfaces of this solid?

15

16 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*)

17 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!

18 Is a location somewhere in the plane Is pretty unimportant when alone; but when you connect it with another, you start making other stuff What can you make by connecting these points on the White Board?

19 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: (#, #) If the room were a coordinate plane, what point would you be?

20 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*)

21 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?

22 Is related to a ray Is also related to a line segment

23 Which do you see here?

24 Which do you see here? (Complete the THIRD PROBLEM SET*)

25

26 In the coordinate plane, it… is described by two traits slope (rise/run) y-intercept has an equation y=mx+b

27 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*)

28 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

29 I want to know how confident you feel about each topic before you leave for the day I will respond to your questions in class or on the sheet
