Overview:
In order to effectively study geometry, students must begin by understanding the basic geometric figures upon which the rest of geometry sits. These figures include points, lines, planes, angles, and polygons. Additionally, students will investigate the line relationships parallel and perpendicular.
Discipline/Content Areas Included:
Definitions of point, line, plane, and angle
Measuring line segments and angles
Calculating distances between two points.
Calculating distance from midpoint to endpoint.
Recognize line relationships.
Identify polygons and calculating perimeter.
Organizer:
1.Why do four-legged chairs sometimes wobble while tripods never do?
2.How do we use units to give meaning to a measurement?
3.Why are there 360° in a circle?
4.How can I be sure that a joint forms a right angle?
5.What is a polygon?
6.How do carpenters, architects, and machinists construct and copy angles and segments?
Targeted Standards:
From Kentucky Learner Goals:
1.5-1.9 – Students use mathematical ideas and procedures to communicate, reason, and solve problems.
1.10 – Students organize information through development and use of classification rules systems.
2.9 – Students understand space and dimensionality concepts and use them appropriately and accurately.
2.10 – Students understand measurement concepts and use measurements appropriately and accurately.
From Program of Studies for Geometry::
M-H-G-1 Students will find angle relationships such as vertical angles, linear pairs, complementary angles, and supplementary angles.
M-H-G-2 Students will identify relationships between and among points, lines, and planes, such as betweenness of points, midpoint, distance, collinear, coplanar, parallel, and skew lines.
M-H-G-3 Students will find the intersection of lines, planes, and solids.
M-H-G-4 Students will connect geometric diagrams with algebraic representations.
M-H-G-5 Students will integrate constructions such as segments and angles, segment bisectors, perpendiculars, angle bisectors, parallel lines, circles, arcs, and polygons.
M-H-G-6 Students will describe, draw, and construct two-dimensional and three-dimensional figures.
