DO NOW
• Find your assigned seat.• Take out your same sheet of paper from
Wednesday. (It should be in the bin.) • Set your culture bag on your desk if you have not
presented.
PRESENTATIONS
• When it is your turn to present, project your voice. • Explain your bag and quote.• Explain how each item represents who you are.
• When it is not your turn to present, listen silently.• On your piece of paper, write down the name of
each presenter. • Write down two things you learn about each
person next to their name.
CLASS COMPETITION
• See if you can beat my other classes (fastest and quietest) at:• Turning in an assignment.• Exiting the classroom.• Entering the classroom.• Rotations• Checking out computers• Putting chairs up• Taking chairs down.
PRETEST
• Take out scratch paper and a pencil.• DO NOT write on the test itself. • Do your best to answer all 20 questions. • When you finish, check out your assigned
computer• Go to www98.achievedata.zoom/test• Enter your code (see my website for "Geometry
Pretest Codes")• Submit your answers until you see a score. Show
Ms. Forsyth your score before you log off.
TODAY’S OBJECTIVES
• Discover geometry in nature, art and world cultures• Discover the characteristics of reflectional and
rotational symmetry• Develop Problem Solving Skills
INTRO TO GEOMETRY
• “Geo” means earth• “Metres” means measure• Geometry began as the study of earth measure
GEOMETRY IN NATURE AND ART
• What characteristics do these figures have that make them pretty, nice, balanced, or regular?
SYMMETRY
• A geometric characteristic of both nature and art.• Two main types:• Reflectional symmetry – you can fold it along a
line of symmetry so that all points on one side of the line exactly match with all the points on the other side of the line.• Rotational symmetry – it looks the same after you
turn it around a point by less than a full circle.
PARTNER DISCUSSION
• Turn to a partner and explain both types of symmetry. • Give a NEW example of each.
