• Lesson Plan
• Subject: Symmetry
• Driving Question: What is symmetry?
• Pedagogical Method: Kinesthetic Learning
• Duration: 50 minutes
• Delivery Method: Synchronous
• ### Purpose

Students will learn to recognize symmetry in daily objects and differentiate between what is symmetrical and what is not.

• ### Before you start

● Materials: laptops/tablets/Mobile phones
Also find attached the necessary resources in the Files section.

• ### Objectives

• Recognize a symmetric figure
• Draw a line of symmetry
• Differentiate between symmetric figures and asymmetric ones
• Apply symmetry in real life

Keywords: symmetric figure, asymmetric, line of symmetry, shapes, equal halves, side

• ### Prior Knowledge

• Grade three students should have an idea about the concept of symmetry being the division of a shape into two identical halves.
• Students should know how to use a ruler and should recognize different geometrical shapes.

• ### Warming Up (10 minutes)

Have students, with the help of their parents, bring one of the following fruits to cut in half (orange, apple, strawberry, peach, kiwi, banana, figs).

After they cut the fruit in half, they will see that the two parts/halves are the same. On the spot, ask the students, each one on his/her own, to try to make an educated guess on what the lesson will be about. This will help build students’ curiosity and expectations.

• ### Learning Activity 1 (15 minutes)

Share a video that explains the concept of symmetry. For grade 2, send Video 1. For grade 3, send Video 2. Project this Link 1 and ask some volunteers to share their answers for the first two or three exercises. Then, send Link 1 to the students and ask them to do the rest.

Have students share their scores with you so you can check for understanding.

• ### Learning Activity 2 (20 minutes)

Assign students to 3 breakout rooms. Each group/room will apply one of these activities:

(Ask your students to prepare the materials needed for the activity before the session).

1. Bring a paper and any water colors you have. Fold the paper in half and then open it. Draw on one side anything you want and then fold the paper again. Open the paper, and you have got your symmetric figure!
2. Bring a paper and draw a line in the middle along the paper. Bring any small objects you have at home (eg. beads, shells..) and place the same pattern on both sides of the line.
3. Bring a leaf. Cut it in half then bring a paper with any glue/scotch tape. Place half of the leaf on the paper and try to draw the same other half on your own.

To check for understanding, have students reflect on their learning by sharing, “I used to think….but now I know…” fact about symmetry.

• ### Wrap-Up (5 minutes)

Have a student recap session. For homework, send Link 3. Students can check their answers on their own and send their results to you. For an assessment, send Link 4 and use Answer Key 1 for instructions and rubric.
