What a brilliant site you have!!! I love it, especially as it saves me hours and hours of hard work. Others who haven't found your site yet don't know what they are missing!
3.G.1 – Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Samples: Identifying shapes based on attributes. Identifying types of lines. Studying the Names of 2D Shapes.

4.GM.2 – Sort objects and two- and three-dimensional shapes by two features simultaneously
Samples: Angles in the environment. Identifying shapes based on attributes. Learning the names of two-dimensional shapes.
5.GM.2 – Sort two- and three-dimensional shapes, considering the presence and/or absence of features simultaneously and justifying the decisions made
Samples: Parallel and perpendicular lines in shapes. Identifying types of lines. Studying the Names of 2D Shapes.
KS2.Y4.G.PS – Geometry - properties of shapes
Pupils should be taught to:
KS1.Y4.G.PS.1 – Compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes
Samples: Studying the Names of 2D Shapes. Combining or splitting 2D shapes. Attributes of two dimensional shapes.
