# Geometry Circle Worksheets - PowerPoint

Document Sample

```					   10 Day Unit

   Teaches basic geometry terms and

   Integrates technology in a fun way
   Taught in 8th grade classroom

   Ages 13 to 14

   Should be briefly introduced

   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 real-
world 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.
