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
