1. 3D Construction Challenge
My task was to use marshmallows and toothpicks to make 3D shapes and then fill in the
marshmallow construction sheet. We had to follow the instruction. The instructions
were to use an amount of marshmallows and toothpicks to make 3D shapes. We also
had to write down the faces, vertices and edges of the shape we make.
I used toothpicks to represent edges and marshmallows to represent vertices.
Based on the clues given, I solved the problems by creating the following models:
Cube, which had 6 faces, 12 edges and 8 vertices
Square pyramid, which had 5faces, 8edges and 5 vertices
Pentagonal prism, which had 7 faces, 15edges and10vertices
Pentagonal pyramid, which had6 faces, 10 edges and 6 vertices
Hexagonal pyramid, which had 7 faces, 18 edges and 7 vertices
Octagonal prism, which had 10 faces, 24 edges and 16 vertices
It was fun to make the 3D shape with marshmallows and toothpicks. It was challenging
not to let the marshmallows stick on my hands. This task made me think about my
math ASA making the same thing as this but not using the sheet.
During this task, I learned more about how to create a 3D shape. Next, I would like to
investigate more about harder 3D shapes and nets.
