Summary and Objective
Students will understand that angles can be found in many items we commonly use. Using historical quilts the students will identify acute, obtuse, right and straight angles.
Teaching Plan
Step 1.
As a pre-activity, the teacher will read aloud "Sir Cumference and the Great Knight of Angleland" by Cindy Neuschwander.
Step 2.
After listening to the story the students create a word wall of angle terms and meanings.
Step 3.
Pass out a copy of the Crazy Quilt. With the whole class, model finding angles in this quilt. Ask the students "Do you see any angles in this quilt?" "Do you think the creators of this quilt were thinking about angles when they made the quilt?" "Do you think the creators were familiar with all of the angles we have included in our word wall? Let's see if we can figure out what angles the creators did use in this quilt." Together discuss and identify what the students observe. The angles identified can be listed on a chart.
Step 4.
Divide the students into small groups and pass out copies of the remaining quilts. Each group examines the quilt pictures. Next, they record their findings by illustrating and labeling the angles they have identified in each picture.
Step 5.
Regroup as a whole class. Each group will share their findings and display their illustrations.
Step 6.
Next,to assess individual understanding each student will create his/her own quilt square including at least one acute, obtuse, right and straight angle. A variety of materials can be made available for each student to create his/her square.
(colored paper, oak tag, wallpaper, contact paper, felt)
Step 7.
Completed squares can be put together on a bulletin board to form a class geometry quilt.
