Do now: lines and angles

1
4-29-13

• Do now lines and angles
• The letter Z illustrates alternate interior
  angles. Find at least 1 other letter that
  illustrates pairs of angles (corresponding,
  alternate exterior, vertical, supplementary)
• Draw the letter
• Then mark and describe the angles

2
density

• What weighs more, a bag of paper or a paper clip?
• Does mass have anything to do with it?

3
instructions

• What objects have certain constraints?
• How is density related to mass and volume?
• Discuss ideas for story problems?
• You will not solve, but need to show what solving
  for

4
Measuring review of volume and area

• Area
• 2 D geometric shapes
• Can you name shapes with area?

• Volume
• 3 D geometric shapes
• Can you name shapes that are similar to area
  shapes but have volume?

5
Circles volume

• A machinist creates a spacer by drilling a 3 cm
  diameter hole through the middle of a cylinder,
  that has a diameter of 5 cm and a height of 0.5
  cm. What is the approximate volume of the
  finished spacer?
• Consider a life saver candy
• Find volume whole thing
• Then find volume what you cut out

6
Partners (these were due Friday 4/26)

• Given 2, 3-D objects, compute effect on volume,
  if a dimension (height) changes,
• Create a visual demonstrating the relationship
  between circumference, area, height, and volume
  of a circle and its relationship to a cylinder

7
Partners (continue) (due 4/29/13 at end of hour)
Create 2 problems for your classmates to solve in
which they must use at least three volume formulas
8
Individual (due 5/3/13)

• How do artists consider geometric shapes when
  creating masterpieces?
• DIRECTIONS Find a picture/character/place that
  interests you. Draw, sketch, or use computer in
  room to create the picture using only geometric
  shapes. Vocabulary is below of some geometric
  shapes that should be involved in your picture
• -Geometric shapes -Cylinder
• -Sphere -Rectangular prism -Parabola

9
Circle information

• What are the parts to a circle?
• What do these parts form?

10
Summary 4-29-13

• Why are volume formulas used for 3D objects?

11
No technology devices allowed during instruction

• This is a new rule that all high school teachers
  are implementing. If I see out, then I will ask
  you to put away once and if still see I take, and
  return at end of class, if problem then admin can
  get

4-30-13

• Do now Transformation
• Your friend and her parents are visiting
  colleges. They leave their home in Enid, Oklahoma
  and drive to Tulsa, which is 107 miles east and
  18 miles south of Enid. From Tulsa, they go to
  Norman 83 miles west and 63 miles south of Tulsa.
• Where is Norman in relation to Enid?

13
Density, volume, mass

• Potato chips
• Pringles

14
Circle/conic sections information

• Conic section is intersection of plane and cone
• Circles have circumference, radius, arcs, use pi
• How are circles related with volume?
• Arc measure
• Arc length

15
Arc length

• Video you tube arc measure vs. arc length

16
Circles/conic sections

• Activity pg 770
• Arc measure and length problems
• Clock problem task
• Book work pg. 777

17
Summary 4-30-13

• How can you prove relationships between angles
  and arcs in a circle?

18
5-1-13

• Do now
• Pg. 777 14

19
Conic sections/ circles

• create a vocabulary sheet that includes
  definitions and diagrams of each type of segment.
  
• Perhaps making a connection that a central
  angle has its vertex in the center of the circle
• Have students to organize all the theorems
  taught in sections 12.1 to 12.4 in an effort to
  increase learning.

5-2-13

• Do now quiz today

21
5-3-13

• Do now
• An ice cream vendor presses a sphere of frozen
  yogurt into a cone. If the yogurt melts into the
  cone, will the cone overflow? Explain
• See picture and measurements on pg 739 46

22
Together Circles and their parts

• Activity pg. 770 (2)
• Why did you refresh the distance formula? Pg.
  799,
• There is a connection with equation of a circle

23
work

• Retake a test/quiz or complete a test/quiz from
  yesterday or a previous day
• Re-create a picture using only geometric shapes
• If finish with all, then work or sit quietly
  until time is up or all students complete

• Pg. 762 (12-1) pages, definitions, questions
• Pg. 771 (12-2) definition, theorems, problems
• Pg. 780 (12-3) definitions, theorems, problems

• Partners

• individual
