Rationale
Vocabulary
Acute Angle - an angle that measure less than 90 degrees
Obtuse Angle - an angle that measures more than 90 degrees but less than 180 degrees
Right Angle - an angle that measures exactly 90 degrees
Straight Angle - an angle that measures exactly 180 degrees
Objectives
The student will be able to identify everyday objects with various types of angles.
The student will be able to explain and demonstrate what each type of angle is.
Lesson Essential Question(s)
How can I check my understanding of acute, obtuse, right and straight angles?
How can I identify everyday objectives with various types of angles?
Duration
6 days - 30-40 minute classes
Materials
iPad
Screencasting app (Show Me, Educreations, Teach/Knowmia, Explain Everything)
Foldable
Whiteboard & markers
Suggested Instructional Strategies
W: | The teacher will post and discuss the essential questions and I can state with the students at the start of each lesson. Students will be shown an example of the screencast they will make to demonstrate success of the concepts. |
H: | The screencast will be a motivating experience for students. Students will also be in whole group, small group, and individual groups to practice the skills taught. A foldable will be utilized to engage students as well. |
E: | Students will work in partners during lessons and individually on his or her screencast. Students will be asked to examine real world objects differently than before and will therefore be a memorable experience for them. |
R: | Various times throughout teaching students will be asked to evaluate his or her success in understanding the types of angles using exit tickets. |
E: | Students will show their understanding by completing the screencast using the rubric as a guide. |
T: | Instruction will be differentiated using the partner activities. The screencasts are also differentiated. |
O: | The progression of the lesson plan is scaffolded so the lesson and activities go from teacher directed to student directed. |
Instructional Procedures
Day 1
- Before class: Teacher posts essential questions and I can statement. Teacher shares with students at the start of class.
- Teacher shows students an example of a completed screencast.
- Teacher discusses four types of angles by demonstrating what they look like as well as providing the definition while completing the foldable
- Students take notes on his or her own foldable
- Exit ticket: Students will write their name on a sticky note as well as a number using the system below.
- Teacher reviews essential questions and I can statement withthe students at the start of class.
- Teacher & students review 4 types of angles using foldable
- Teacher draws various angles & students identify by writing the name on his or her white board
- Students work in partners - one draws an angle the other identifies it - change roles
- Teacher draws various 2-dimension shapes & as a whole group students identify
- Scaffold instruction so eventually students are identifying all angles in shape
- Teacher discusses rubric with students & shows a completed screencast
- Teacher models how to complete screencast (take & insert picture, format, record voice)
- Students explore the app & its features
- Teacher takes students in small groups around the school to locate real world objects and the angles they have
- Students take pictures of objects
- Students begin to make screencast
- Students continue to work on screencast and practice presenting it
- Students present screencast
- Teacher scores screencast using the rubric
Formative Assessment
The teacher will monitor students during instruction and adjust instruction based upon success of lack of success of student understanding. A + or - system is used for each student to help determine level of success. The exit tickets also serve as a formative assessment. The teacher will re-teach concepts and ideas as deemed necessary.
