- Duration: 50 minutes
- Delivery Method: Messenger Applications
Students will learn to recognize symmetry in daily objects and differentiate between what is symmetrical and what is not.
- Materials: laptops/tablets/Mobile phones
- 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
- Grade 3 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.
Have students, with the help of their parents, choose 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, and in the video, they should talk about what happened and their thoughts.
At this point, students will start predicting the lesson. They may think the lesson is about getting the half of different shapes/things or about equal shares (division maybe) or fractions as well.
Have students will make a video and send it to you. Share your students’ videos on the group chat.
Send a video that explains the concept of symmetry. For grade 2, send Video 1. For grade 3, send Video 2.
To check for understanding, send a game link (Link 1). Have students match the same halves together. There are different objects to match from shapes to letters to real-life images. Have them share their scores with you.
Send Link 2 to the students. They will have to draw and paint to master symmetry skills.
Have students choose one of these activities to apply:
- 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!
- 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.
- 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.
Have a student recap by sending a voice note about what the session was about. 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.
