1
Hour one Feedback Review ANGLE Hour two ANGLES and LINES Project intro Hour three Check-ins Bearing angles
2
Some themes… River, state-to-state travel, music, sleep Persistent math issues Persistent test issues (anxiety, etc.) Issues with teachers
3
Some themes… River, international travel, music Persistent math issues Persistent test issues Issues with geometry
4
Can I use an audio recorder? Line: what is formula for slope? Line: how do you solve for b? (Is there a formula for b?) Line: what about slope to the left?
5
Plane: treat the scale as the amount between each hash mark (edge of each box) Why not always use a scale of 1? What can I do if I get done early? What kind of dog do you have?
6
How many (line) segments are in a pyramid? What is parallax? Line: Is the y-intercept a point? Are “axes” different from “axis”?
7
Do you actually know the answers to the problem sets? Can we use our notes on the tests? Will we do proofs? (“please no”)
8
“I work better listening to music” “We had trouble using the order of operations” (exponents mentioned by another) How old are you?
9
Why do you teach math? Can you determine how big the sun is using a coordinate plane? What’s the best way to remember all this stuff?
10
PlanePoint LineAngle Flat (2-D) Shapes Solids (3-D)
11
Having trouble with slope? Try using the slope formula: (Complete the FIRST PROBLEM SET)
12
Is made by two lines, rays, or segments that meet (at the vertex) Has size (measured in degrees) Is described using three points
13
Some exact sizes are named: Right (90 o ) Straight (180 o )
15
Some ranges of sizes are named: Acute (between 0 o and 90 o ) Obtuse (between 90 o and 180 o )
16
Some combinations are named: Adjacent (two that share a ray) Opposite (two that are across an intersection of lines)
17
More combinations are named: Complementary (add up to 90 o ) Supplementary (add up to 180 o )
18
Measure angles on paper using a protractor Identify individual angles as right, straight, acute, or obtuse Identify pairs of angles as adjacent, opposite, complementary, or supplementary (Complete the SECOND PROBLEM SET)
20
Some combinations are named: Perpendicular (meet at 90 o ) Parallel (never meet, have same slope)
21
A line that crosses or bridges two parallel lines is called a transversal
24
When a transversal crosses parallel lines, there are many pairs of equal angles
25
Corresponding angles
26
Alternate interior angles
27
Alternate exterior angles
28
Identify perpendicular and parallel lines Find missing angles’ sizes where parallel lines are crossed by a transversal (Complete the THIRD PROBLEM SET)
32
Complete the FOURTH PROBLEM SET Complete the FIFTH PROBLEM SET Show me when you’re done and I will check today’s assignment Fill-in your check-in sheet for today
33
N38 o W = “north 38 degrees west” N S E W
