Students identify and draw figures based on a given set of attributes.  Figures include triangles, quadrilaterals (squares, rectangles, rhombuses, parallelograms, and trapezoids), pentagons, and hexagons.  They will categorize two-dimensional figures based on their definable attributes by using formal and informal language.  Students will also identify lines of symmetry for a two-dimensional figure.

B.E.S.T. Benchmarks:

• MA.2.GR.1.1 Identify and draw two-dimensional figures based on their defining attributes. Figures are limited to triangles, rectangles, squares, pentagons, hexagons and octagons.
• MA.2.GR.1.2Categorize two-dimensional figures based on the number and length of sides, number of vertices, whether they are closed or not and whether the edges are curved or straight.
• MA.2.GR.1.3 Identify line(s) of symmetry for a two-dimensional figure.

Key Concepts:

• I can identify two-dimensional figures (triangles, rectangles, squares, pentagons, hexagons, and octagons) based on their defining attributes.
• I can draw two-dimensional figures (triangles, rectangles, squares, pentagons, hexagons, and octagons) based on their defining attributes by using a ruler or a straight edge.
• I can categorize two-dimensional figures such as triangles, rectangles, squares, pentagons, hexagons, and octagons based on the number and length of sides, number of vertices, if they are closed or not, and if the edges are curved or straight.
• I can use formal and informal language to describe defining attributes when categorizing.
• I can identify line(s) of symmetry for a two-dimensional figure.
