Navigating DC by the Angles
Objectives:
At the conclusion of this lesson, the student will be able to identify the following:
Vertical angles
Alternate interior angles
Alternate exterior angles
Corresponding angles
Same-side (consecutive) interior angles
Linear pairs
Prior Knowledge:
Students should be familiar with the following concepts:
Parallel lines
Perpendicular lines
Transversals
Supplementary and complementary angles
Lesson:
Provide students with the following definitions:
Vertical angles: two nonadjacent angles formed by 2 intersecting lines
Alternate interior angles: congruent angles between parallel lines and on opposite sides of a transversal that cuts through the parallel lines
Alternate exterior angles: congruent angles on the outside of parallel lines and on opposite sides of a transversal that cuts through the parallel lines
Corresponding angles: congruent angles in the same position but on different parallel lines
Same-side (consecutive) interior angles: supplementary angles between parallel lines and on the same side of a transversal that cuts through the parallel lines
Linear pair: a pair of adjacent angles whose noncommon sides are opposite rays
Load activity center setting file DCMAP.act
Divide students into groups. Teacher BEGINS class. Have students log into TI Navigator system and then the activity center. Then teacher BEGINS activity.
Distribute handouts (See file Touring DC by the Angles). Each group should discuss their tour and determine final position. Have each group leader show route by contributing points into the Activity Center.
Assessment:
Once tours are complete, teacher ENDS activity center. Students then log into NETWORK APPLICATIONS and LEARN CHECK. Teacher SENDS PARALLELS.EDC. Students are to complete the PARALLELS.EDC file.
Once students have finished the learning check file, teacher COLLECTS answers and reviews results with class.
Extensions:
As an algebra review, students can play match my graph to try to find the equations of lines for the streets in the background image map of Washington, DC.
