Properties of shape - Draw 2D shapes - Presentation

In the lesson on drawing 2D shapes, students are encouraged to use their understanding of sides and vertices to create various geometric figures. The class begins with an interactive discussion about these fundamental properties, using physical shapes as references to identify and show sides and vertices. Following this, students are invited to use a geoboard, a tool that allows them to form different 2D shapes such as rectangles, squares, and triangles. The activity prompts them to think about where to start drawing a shape, emphasizing the importance of precision and technique in replicating these shapes on dotted and squared paper.

The teaching slides guide students through several activities designed to enhance their fluency and reasoning skills in geometry. One task involves rotating the paper to achieve more accurate drawings, while another challenges students to build a 2D shape on a geoboard and then copy it onto both dotted and squared paper, checking for accuracy. Further reasoning exercises encourage students to explore the creation of various squares on a geoboard, to guess shapes hidden under spilt paint, and to follow instructions for drawing complex figures. These activities not only reinforce the properties of 2D shapes but also promote critical thinking and problem-solving. The lesson concludes with independent work where students draw different triangles, compare their work, and discuss the efficiency of starting points and the necessity of using a ruler for precision.
