Learning Objective: After modeling for a class and practicing portioning shapes into two equal parts as a class, students would be able to portion circles and rectangles into two equal shares, with 80% accuracy.
Applicable Common Core Learning Standard:
CC.4. MD. 3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.
Link with Prior Knowledge:
Key Vocabulary:
• formula
• perimeter
Materials:
• mystery bag with supplies for room redecorating
• smartboard
• perimeter worksheet
• pencils
Motivation:
Bring the mystery bag with a paintbrush, a ruler, a measuring tape, ext. Ask students to make predictions what could be inside the bag. After students would share their predictions with a class, start pulling the object out of the bag one by one, naming each of them. Put objects in the …show more content…
Assessment:
Assessment for this lesson would come from informal observation of students during the group work and a whole class discussion, from assessment of their individual work (worksheets), and from assessment of their homework.
Classroom Management:
Try to interact with all students. Walk around the classroom and assist students who need additional help. Remind students to stay on task. Use encouragements and positive reinforcements to keep students on task.
Attention to Multicultural Issues:
Create time and forum for questions and clarifications (questions pauses). Repeat and clarify important points. Wait longer to let students formulate their responses during a whole class or group discussion. Introduce a word perimeter in different languages (English, Spanish, Chinese, and Russian), and put in on the bulletin
