1.G.1 Distinguish between defining attributes, e.g., triangles are closed and three-sided, versus non-defining attributes, e.g., color, orientation, overall size; build and draw shapes that possess defining attributes.

• They will identify shapes based on their defining attributes. For example, they could shown a shape and asked to identify whether it's a triangle or not, based on its defining attributes.

• They will drag and drop shapes into categories of defining attributes and non-defining attributes. They must explain why each shape belongs to its respective category.

• For example, they could be tasked with creating a triangle with three equal sides. They must apply their understanding of defining attributes among different shapes.

• Students will analyze data about different shapes, including their defining attributes like number of side, angles, and whether they are closed or not. They will create graphs and charts to compare these attributes among different shapes.

• Students will create a presentation showcasing various shapes and their defining attributes. They can include interactive elements like clickable shapes the reveal information about their attributes when selected. This activity encourages students to creatively present their understanding of shape attributes.

• In groups, students design shapes using a digital drawing tool and share their designs on Padlet. They will evaluate each other's designs based on whether they accurately represent the defining attributes of the given shape.
