Transcript Geometry
10 Day Unit
Teaches basic geometry terms and
concepts to 8th grade students
Integrates technology in a fun way
Taught in 8th grade classroom
Ages 13 to 14
Should be briefly introduced
Review and advance knowledge
Classroom includes wide range of
learners
M.O.8.3.1 Justify the relationships among corresponding,
alternate interior, alternate exterior and vertical angles when
parallel lines are cut by a transversal using models,
pencil/paper, and technology.
M.O.8.3.2 Classify polyhedrons according to the number and
shape of faces; use inductive reasoning to determine the
relationship between vertices, faces and edges (edges + 2 =
faces + vertices).
M.O.8.3.3 Identify, apply, and construct perpendicular and
angle bisectors with and without technology given a realworld situation.
M.O.8.3.4 Create geometric patterns including tiling, art
design, tessellations and scaling using transformations
(rotations, reflections, translations) and predict results of
combining, subdividing, and changing shapes of plane
figures and solids.
M.O.8.3.5 Create scale models of similar figures using
ratio, proportion with pencil/paper and technology and
determine scale factor
M.O.8.3.6 Make and test a conjecture concerning
regular polygons, the cross section of a solid such as a
cylinder, cone, and pyramid, the intersection of two or
more geometric figures in the plane (e.g., intersection
of a circle and a line), and justify the results.
21C.O.5-8.2.TT3 Student uses multiple technology tools
for gathering information in order to solve problems,
make informed decisions, and present and justify the
solutions.

Day 1
• Review basic
concepts & terms
• PowerPoint
Presentation
• Handout with
PowerPoint
Day 2
• Lines & Angles
• Geometer’s
Sketchpad with
Smartboard
• Students construct
object on board
Day 3
• Review angles with
bulletin board
• Worksheet on
bulletin
• Introduce 3-D
objects with
classroom object
• List objects for
homework
Day 4
• Student with most
examples gets a
prize
• Introduce three day
long project
Building project with
group
Need to know how
geometric factors are
functional in project
Day 5
• Entire class time to
work on building
projects
• Ask question while
they work as a
group
Day 6
• Each group gives a
3-5 min.
presentation about
their building
• Graded on
Presentation and
overall project
Day 7
• Classroom
discussion on
polyhedrons
• Create own
polyhedrons and
turn in for a grade
• Last 20 minutes
doing internet
activity
Day 8
• Worksheet
reviewing previous
day
• Discuss symmetry
and transformations
• Each students
comes to board to
draw line of
symmetry
Day 9
• Watch movie – “The
Standard Deviants –
Geometry (pt. 1 &
2)”
• Worksheet on video
to keep students on
task
Day 10
• Instead of formal
exam students
participate in a
variety of activities,
including Geometry
Simon Says.
Individual and group activities
Wide range of learning styles
Most work completed on their own
Required handouts to be turned in for
grades
Hold attention with various forms of
technology ranging from the interactive
Smartboard, to online activities
M.O.8.3.1 – Presentation on building project
M.O.8.3.2 – Create own polyhedrons
M.O.8.3.3 – Construct building and give
presentation
M.O.8.3.4 – Students come to board to
demonstrate symmetry and create tessellations
M.O.8.3.5 – Unofficially evaluated while working on
building project
M.O.8.3.6 – Evaluated by giving examples of 3-D
objects for homework
21C.O.5-8.2.TT3 – Informally assess student’s basic
understanding of symmetry by using the
Smartboard on day 8
