Unit Topic:
Unit #6 Connecting Algebra and
Geometry Through Coordinates
Standard(s):
MCC9.G.GPE.4 Use coordinates to prove simple geometric theorems algebraically.
MCC9.G.GPE.6. Find the point on a directed line segment between two given points that partitions the segment in a given ratio.
MCC9.G.GPE.7. Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance
formula.

(Some ideas: KWL, Pre-reading, Think Pair Share, Thinking Maps, Vocabulary Overview, Word Splash, Survey, Big Four)
TTW ask students to
graph a rectangle (or
triangle) on the
coordinate plane and
ask them how they
would find the
perimeter. Area?
Students will
As a bellringer: TTW

of the height of the
triangle. TTW ask

students how they will
find the area of the
triangle.
Cognitive Teaching Strategies: include time for distributed practice or summarizing

Diagrams/Graphs, Comprehension)
TTW lead students in
Partitioning a Line
Segment PowerPoint –
referencing similarities
to midpoint. TTW model
how to partition a line
segment into a given
ratio. Students will
practice whole group
with examples from the
powerpoint.
TTW use TE AL43 as
a guide for
instruction. Students
will graph rectangle
GHJK on their graph
paper and TTW lead
students in finding the
area and perimeter of
triangles, quads, and
rectangles. Students
will copy examples in
composition book.
TTW lead students in
review of finding area
and perimeter of
special quads and
triangles on coordinate
plane. Specific
attention will be paid to
classifying special
quads and triangles.
Quick bellringer review
of partitioning line
segment and parallel/
perpendicular lines.
Lesson is an extension
of area of triangle.
TTW give students
graphic organizer and
lead them in finding
the distance between a
point and a line which
will help them to find
the height of the
triangle in the
activator. TTW lead
students in guided
notes in their
composition books for
finding heights of these
types of triangles.
