Tuesday, Sept 23 Math Homework Study Links pg. 5 Table Leaders: Pass out reference books & get rulers from Ms. Smith Individuals: Have orange notebook on desk; put everything else away. Geometry: Lesson 1 Target/Objective: I can identify and describe characteristics of line segments, lines, and rays. Math Message Open your Student Reference Book to page 88. Let’s read, “Geometry in Our World,” together. Shoulder Partner Activity: – List three places, from the text, where geometry can be found in our world. – Look around the classroom and find three geometric shapes or figures. Geometry: Math Vocabulary • Point: a location in space – Usually made with a dot ( ) to show where the point is. • Line Segment: is made up of 2 endpoints and the straight path between them A Endpoint B Endpoint Math Vocabulary • Ray: a straight path that has a starting point and goes on forever in ONE direction. A B • Line: a straight path that goes on forever in BOTH directions. B A Line Segments B A • In your notebook, draw two points and label the points A and B. • Use your straightedge to connect the points (don’t allow your line to cross the two points). • Naming this line segment • Line segment AB Line segment BA • AB BA Lines B A • In your notebook, draw two points and label the points A and B. • Use your straightedge to connect the points. This time extend the line on both ends and use arrowheads to show that it’s continuous. • Naming this Line • Line AB Line BA • AB BA How is a line different from a line segment? Rays B A • In your notebook, draw two points and label the points A and B. • Use your straightedge to connect the points. This time, extend the line on one end only (past point B). Use an arrowhead to show that it’s continuous. • Naming this Ray • Ray AB AB Shoulder Partner Activity • How many line segments can you name using the points marked on this line? X Y Z • How many rays can you name using the points marked on this line? Independent Practice Complete problems 1-4 on page 4 of your math journal. Early Finishers: Work on Math Boxes pg. 5 Voice Level: 0 Time: 5 minutes Wrap Up! • Did we achieve our target/objective? – I can identify and describe characteristics of line segments, lines, and rays. • Table Leaders: Put away Reference Books • Individuals: Get ready to move classes
