![]() Understand that attributes belonging to a category of 2D figures also belong to all subcategories of that category.Classify 2D figures in a hierarchy based on properties.Recognize a line of symmetry for a 2D figure and be able to draw these.Recognize and identify right triangles as a category.Classify 2D figures based on the presence or absence of parallel or perpendicular lines and angles of a specified size.Identify points, lines, line segments, rays, and angles and perpendicular and parallel lines in 2D shapes.Recognize rhombuses, rectangles, and squares as examples of quadrilaterals and be able to draw these quadrilaterals, as well as other quadrilaterals that do not fit these categories.Shared attributes can define a larger categories (ex: quadrilaterals).Understand that shapes in different categories may share attributes (ex: a rhombus and a rectangle has the same number of sides).Draw and recognize shapes having specified attributes (ex: a given number of angles, or a given number of faces).Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.Use shapes to create a composite shape, and compose new shapes from the composite shape.Compose 2D (rectangles, squares, trapezoids, triangles, half-circles and quarter-circles) and 3D shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders).Distinguish between defining attributes (ex: triangles are closed and three-sided) versus non-defining attributes (ex: color, orientation, size).Model and/or draw shapes in the world, and compose simple shapes to form larger shapes.Compare 2D and 3D shapes to describe how they are the same and different, their parts (corners, sides) and other attributes (having sides that are equal).Recognize the difference between 2D (“flat”) and 3D shapes (“solid”) and name common 2D and 3D shapes, including: 2D shapes 3D shapes.Here’s what children will be taught about the properties of shapes through each grade level: When will children learn about the properties of 2D and 3D shapes? We will go into more detail classifying these below. We will go into more detail classifying these below.ģD shapes have three dimensions, such as width, height and depth. ![]() Download Free Now!
