Lesson Plan : Points, line segments
Teacher Name: | Juergens |
Grade: | Grade 4 |
Subject: | Math |
Topic: | To introduce tools for geometry; and to review points, line segments, lines and rays. |
Content: | *Identify and draw line segments, lines, and rays. *Describe characteristics of line segments,lines and rays. *Use letter symbol notation to name line segments, lines and rays. Key vocabulary: point, line segment, endpoint, line, ray |
Goals: | Students will be able to recognize a point, line segment, line and a ray. Students will also recognize that geometry is everywhere. |
Objectives: | Students will be able to independently complete/(draw) student page 4/Math journal....points, line segments and rays. Additionally, students will play "addition top it" to develop automaticity with addition facts. |
Materials: | Student Reference book..pg 88,89 Math Journal 1, pg 4 Math Journal pg 5 (Math Boxes) Addition Top It or Addition Flashcards Math Masters pg 506 (for recording several rounds of top it) (?) Study Link 1-2 (assess extra practice of this lesson) |
Introduction: | Pass out slates...dry eraser marker. Pose the problem: (How much is 12-7?). Students write the answer on their slates. Do about 12 mental math calculations togehter having the students reveal their answer each time. Geometry Focus: Students read p 88 and p 89 Geometry in our World. Generate a discussion about the article. Use the classroom to have the students give examples of geometry in the classroom. |
Development: | Teacher presents: draw two dots and lable them A and B. Tell students that the dots represent points. Use a straightedge to connect the dots. Remind the class that this figure is called a line segment and the letters are often used to name line segments. Explain endpoints and lines. |
Practice: | Students will practice line segments, points, endpoints, lines on their white boards and label each. The book references math journal pg 4 (I think this is too difficult and I like the Study Link pg 8 better). Text also references math boxes 1-2 pg 5...this can be completed independently. |
Accommodations: | Use the white board and have students practice drawing line segments, lines and rays. |
Checking For Understanding: | Have students explain the difference between a line segment and a line. Students are making adequate progress if they are able to explain that a line segment has a beginning and an end, and a line continues in both directions without end. |
Closure: | Review definitions of: points, line segment, endpoints, ray and line. Provide an example of each for display. |
