Students have to walk around the school compound to capture live photos of 3D objects they've found in their surroundings using iPads.
2. Students will gather the photos and categorize them according to different shapes.

2. Students will cut and fold the nets.
3. During this process, they will analyse and recognize the properties of 3D shapes including faces, edges and vertices.]]> 2022-05-25 00:59:22 UTC https://padlet.com/yingtorngong/Bookmarks/wish/2198501315 https://padlet.com/yingtorngong/Bookmarks/wish/2198501752 1. In the previous activity, the students have analysed and identified the properties of 3D shapes

2. Hence, in the present activity, the students' eyes are blindfolded, they have to touch, move and manipulate the 3D shapes on the table. 

3. During this process, they should be able to guess and get the correct name of the particular 3D shapes, as they are capable to give simple arguments to prove their reasonings. For instance, they may have the thoughts, "This is not a cuboid and cube, as it can be rolled on the table. " "This is not a cone as it has 8 vertices."]]> 2022-05-25 00:59:37 UTC https://padlet.com/yingtorngong/Bookmarks/wish/2198501752
