Angles, Lines, and Movement, Oh My!
Students will be able to identify lines and angles.
Introduction (10 minutes)
Explicit Instruction/Teacher Modeling (10 minutes)
- Write each vocabulary word on the board, including acute angle, obtuse angle, right angle, straight angle, intersecting lines, parallel lines, and perpendicular lines, and draw a picture to remind your students of what it means.
- As you go through the vocabulary, assign a hand and arm movement to each word. For example, a right angle could be represented by arms formed in an "L" shape and perpendicular lines could be represented by your students crossing their arms in front of their chests.
- Have students stand up and spread out and go through each of these terms once.
- Remind students of the angles' degree measurements.
Guided Practice/Interactive Modeling (10 minutes)
- Divide students up into groups.
- Have one student in each group call the names of the vocabulary words and have the rest of the group members do the motion.
- Let all students get the chance of being a caller.
- Walk around and monitor all actions, correcting movements and misconceptions about the terms meanings.
Independent Working Time (10 minutes)
- Pass out the Name that Angle! worksheet.
- Circulate around the classroom to answer any questions your students may have.
- Enrichment: Have advanced students draw everyday objects and label any angles they find.
- Support: Make flashcards of the key terms for your struggling students.
Assessment (10 minutes)
- Take note of struggling students during the Guided Practice game.
- Check the Name that Angle! worksheet for correctness.
- If desired, an exit ticket could consist of asking students to perform a series of hand and body movements associated with the terms.
Review and Closing (5 minutes)
- Play Simon Says using the terms and body motions created at the the beginning of the lesson.
