STAGE I – DESIRED RESULTS
LESSON TOPIC:Circles
BIG IDEAS:
(Content standards, assessment anchors, eligible content) objectives, and skill
focus)
M11.A.3.2 Use estimation strategies in problem-solving situations.
M11.B.2.1
Use and/or compare measurements of angles.
M11.B.2.3
Describe how a change in one dimension of a figure (2 or
3 dimensional) affects other measurements of that figure.
M11.C.1.1
Identify and/or use parts of circles and segments
associated with circles
UNDERSTANDING GOALS (CONCEPTS):
Students will understand: how to use estimation to solve problems for which an
exact answer is not needed.
Describe and explain the amount of error that may exist in a computation using
estimates.
Select and use appropriate units and tools to measure to the degree of accuracy
required in particular measurement situations.
Measure and compare angles in degrees and radians.
Describe how a change in linear dimension of an object affects its perimeter, area
and volume.
Use the properties of angles, arcs, chords, tangents and secants to solve
problems involving circles.Volume of cones, cylinders, spheres, prisms and
pyramids
ESSENTIAL QUESTIONS: How can we show that volume is
an extensions of arithmetic properties and processes, and how
can we use polynomials to solve problems?
VOCABULARY: •
Inscribed, inscribed angle,
circumscribed, tangent line, secant line, chord, central angle,
arc, minor arc, major arc
STUDENT OBJECTIVES (COMPETENCIES/OUTCOMES):
Students will be able to:
1.
Identify and use parts of circles. Solve problems
involving the circumference of a circle.
2.
Recognize major arcs, minor arcs, semicircles, and
central angles and their measures. Find arc length.
3.
Recognize and use relationships between arcs and
chords, and between chords and themselves.
4.
Find measures of inscribed angles. Find measures of
angles of inscribed polygons.
5.
Use properties of tangents, solve problems involving
circumscribed polygons
6.
Find measures of angles formed by lines intersecting
on or inside, or outside a circle.
7.
Find measures of segments that were in the interior
or exterior of a circle.
8.
Write the equation of a circle, graph a circle on a
coordinate plane.
STAGE II – ASSESSMENT EVIDENCE
PERFORMANCE TASK:Daily warm ups, homework, study
island, PSSA anchor test, foresight scores, unit test
FORMATIVE ASSESSMENTS:
#1. Pre-Assessment
#2. Think-Pair-Share
#3. Summarizing Main Ideas
Others:
STAGE III: LEARNING PLAN
INSTRUCTIONAL
PROCEDURES:
MATERIALS AND
RESOURCES:
Active Engagements used:
#1. Note-Taking
#2. Compare Contrast
Others:
warm ups
PSSA Warm Up
Test
whiteboards
Describe usage: Check for
understanding and summarizing
using warm up, homework,
formative assessment questioning
or exit tickets to determine
whether to continue lesson or do
interventions as needed. (model,
spiral scaffolding, instruct/
reteach as needed)
Scaffolding used:
#1. Guided Notes
#2 . Build Vocabulary
Others:
Describe usage: Warm up to
include spiraling review of prior
knowledge to include upcoming
lesson. All notes are guided notes
to build vocabulary, interspersed
with group activities. Graphic
organizers utilized when
appropriate to compare/contrast
