2/23/15 – 2/27/15
What are we learning? 11.4 Circumference and Arc Length
Daily Objective:
 I will be able to find the circumference and arc length of a circle.
TEKS/AP/Standards:
 G.2.B: The student analyzes geometric relationships in order to make and verify
conjectures.
 G.5.A: Use numeric and geometric patterns to develop algebraic expressions
representing geometric properties
 G.5.B: Find areas of sectors and arc lengths of circles using proportional reasoning
 G.8.A: Find areas of regular polygons, circles, and composite figures.
 G.8.B: Derive, extend, and use the Pythagorean Theorem
 G.9.C: Formulate and test conjectures about the properties and attributes of circles
and the lines that intersect them based on exploration and concrete models
How will we learn it?
Learning Activities:
 Guided Notes/Practice
How will we tell if we’re learning it correctly?
Assessment Methods:
 Guided Practice
Checks for Understanding:
 Teacher will walk around while students are working on guided practice.
What do I need to be successful?
Materials:
 Chapter 11B Packet
What do I need to before next class?
Follow Up/HW:
 HW: Complete 11.4 WS
