Step 1: Lesson Standards & Learning Goals
2-Dimensional Shapes: In Grade 2 students are expected to recognize, draw, and describe triangles, quadrilaterals, pentagons, and hexagons based on specific defining attributes. Students are expected to use the terms vertices and angles instead of the informal words corners or points. However, students do not learn the specific types of angles until Grade 4. Students should have ample experiences to recognize, draw, and describe shapes that are traditional looking as well as other shapes that share defining attributes but may look different than traditional looking shapes (a triangle with a vertex at the bottom).
Students are expected to identify squares, rectangles, and trapezoids as quadrilaterals. Note: North Carolina has adopted the exclusive definition for a trapezoid. A trapezoid is a quadrilateral with exactly one pair of parallel sides.
3-Dimensional Shapes: Students are expected to recognize and describe two-dimensional shapes used to construct rectangular prisms (squares or rectangles) and cubes (squares). With 3-dimensional shapes, second grade students are expected to identify and describe attributes of rectangular prisms and cubes including the number of faces, edges and vertices. Students are not expected to draw three-dimensional objects.

Two- and three-dimensional objects with or without curved surfaces can be described, classified, and analyzed by their attributes.
A 2_D shape can be identified by the number of sides, vertices, or angles.
Cubes and rectangular prisms are three-dimensional shapes.
Cubes have 8 vertices and 6 faces of equal size.
Rectangular prisms have 8 vertices and 6 faces with opposite faces being equal.
Any closed figure, without a curved surface, is known as a polygon.
Circles are not polygons.
All closed polygons with four sides and four angles are also known as quadrilaterals. All closed polygons with three sides and three vertices are triangles. All closed polygons with five sides and five angles are pentagons. All closed polygons with six sides and six angles are hexagons.
Shapes remain the same if they are flipped or rotated.
