Common Assessment(s): LAD Task: Moving Those Shapes

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 two dimensional shapes based on the attributes of sides and angles.	Shape riddles, Addison Wesley, p. 298. Geoboard activities, Marilyn Burns. Give a written explanation comparing and contrasting a square and a rectangle.	Students will be given a list of shapes. They will then draw the shape and list 2 attributes that apply to that shape. compare and contrast shapes with written explanations.	attributes shapes geometry quadrilateral trapezoid rhombus octagon parallelogram pentagon radius diameter line line segment point ray
3. Use transformations such as slides, flips, and rotations.	Demonstrate congruency by sliding, flipping and rotating two dimensional shapes.	.	Houghton Mifflin, Gr. 4 Teacher manual, p. 12-13, mask making. Explain your mask in terms of geometric shapes. Alternate assessment: Have students make various shapes they have studied using tangrams or geoboards. Observe while they construct the shapes you describe.	congruent slide flip rotation (turn)
4. Use the properties of shapes and figures to describe the physical world.	Describe how the physical world around them is made up of three dimensional figures.	.	Find 10 real life geometric shapes in classroom or home. Take one example and explain why that shape is used.	properties attribute cylinder rectangular prism triangular prism
