Students will understand and apply concepts from geometry.
Common Assessment(s):

Performance Indicators Students will be able to:	Essential Elements (Specific grade level learning objectives)	Suggested Performance Activities	Suggested Classroom Assessments	Vocabulary
1. Describe, model, and classify shapes and figures using applicable properties.	Name and describe squares, rectangles and triangles based on learned attributes.	Shape riddles, Addison Wesley, p. 298. Geoboard activities, Marilyn Burns	Students will be given a list of shapes. They will then draw the shape and list 2 attributes that apply to that shape.	attributes shapes geometry polygon acute angles obtuse angles right angles vertex vertices parallel lines perpendicular lines
2. Experiment with shapes and figures to make generalizations regarding congruency, symmetry and similarity.	Identifying congruent, similar and symmetrical shapes.	Houghton Mifflin '95, p. 370-379 Pentominoes	Students will be given several upper case letters (ex. A, C, O, P) and will draw all lines of symmetry in each. Students will select congruent and similar shapes on a worksheet.	lines of symmetry symmetrical congruent similar
4. Use the properties of shapes and figures to describe the physical world.	Identify three dimensional figures in the world around them.	Students will brainstorm examples of spheres, cubes, and cones in the classroom. They will chart characteristics of these shapes (number of faces, vertices, edges)	Find 10 real life geometric shapes in classroom or home. Take one example and explain why that shape is used.	symmetry attributes properties sphere cube cone
