Properties of shape - Construct 3D shapes​ - Presentation

In the ninth lesson of a series on the properties of shape, students are introduced to the exciting task of constructing 3D shapes. The lesson aims to familiarise them with the terminology specific to three-dimensional geometry, such as vertices, faces, and edges. Students are encouraged to discuss and describe various 3D shapes using these terms, setting the stage for hands-on activities that will deepen their understanding of geometric concepts. The lesson is structured to allow students to explore the construction of 3D shapes through engaging and interactive methods.

The first activity invites students to use straws and Play-Doh to create a 3D model, promoting creativity and practical application of their knowledge. Following this, they are tasked with cutting and folding provided templates to form 3D shapes, further reinforcing the lesson's objectives. Reasoning exercises challenge students to consider the possibilities of constructing different shapes with a limited number of materials, such as creating various 3D shapes with 12 straws and 8 balls of Play-Doh. The lesson also includes true or false questions to test students' understanding of the shapes that can be made from different combinations of geometric figures. Independent work encourages students to compare their creations, identify similarities and differences, and analyze the components of 3D shapes, such as determining the number of straws and Play-Doh balls needed to construct specific shapes.
