Describe, classify, construct, and relate three-dimensional objects and two-dimensional shapes, using mathematical vocabulary to describe their properties
|
- explore and describe real-world and three-dimensional objects using descriptive attributes such as big, little, like a box, and like a can
- explore, identify, and classify three-dimensional objects in the environment according to their properties
- construct three-dimensional objects using materials such as plasticine, blocks, and boxes
- identify and describe specific two-dimensional shapes such as circles, squares, triangles, or rectangles
- construct and rearrange a design using a set of two-dimensional shapes
- compare, sort, classify, and pattern two-dimensional shapes
|
- compare, contrast, sort, and classify two-dimensional shapes and three-dimensional objects using two or more attributes
- identify, count, and describe the faces, vertices, edges, sides, and angles of polygons and solids
- describe and name three-dimensional objects (cubes, spheres, cones, cylinders, pyramids, and prisms) and use appropriate two-dimensional names to describe their faces
- describe and name pyramids and prisms by the shape of the base
- construct skeletons of a three-dimensional object from a model and relate the skeletons (nets) to models
- demonstrate through dismantling that a rectangular solid has more than one net
- make identical, congruent two-dimensional shapes
- construct and rearrange a design using a set of two-dimensional shapes
- recognize congruent three-dimensional objects and two-dimensional shapes in the environment
- explore the concepts of points, lines, perpendicular lines, parallel lines, and intersecting lines on three-dimensional objects
|
- design and construct nets for pyramids and prisms
- relate nets to three-dimensional objects
- compare and contrast pyramids and prisms to describe a relationship
- identify and sort specific quadrilaterals, such as squares, rectangles, parallelograms, and trapezoids
- classify angles in a variety of orientations according to whether they are a right angle, less than a right angle, or greater than a right angle
- recognize, draw, and name the following: point, line, parallel lines, and intersecting lines
