FORMATIVE ASSESSMENT TASK
Instructions for Implementing the Task
This task can be implemented individually, with small groups, or with the whole class.
 The teacher asks the student to complete the problem on the Pyramid Project worksheet.
 The teacher asks followup questions, as needed.
TASK RUBRIC
Getting Started 
Misconception/Error The student is not able to correctly draw a net for the given threedimensional shape. 
Examples of Student Work at this Level The student:
 Is unable to draw a net of the pyramid.
 Draws an incorrect representation of the pyramid that may or may not be labeled.

Questions Eliciting Thinking What is a net?
What twodimensional shapes are used to make this prism?
What shape is the base? What shape are the faces? How many faces are there?
Can you identify the dimensions of the base (or face)? 
Instructional Implications Define a net as a twodimensional representation of a threedimensional shape that will fold to recreate the threedimensional shape. Ensure the student is familiar with the terms used to describe the parts and dimensions of threedimensional figures including face, edge, vertex, slant height, and base. Provide opportunities for the student to decompose threedimensional figures into nets composed of familiar twodimensional shapes. Guide the student to clearly identify the decomposed parts and label the relevant dimensions.
Provide manipulatives such as pattern blocks or a for the student to explore in order to gain handson experience with creating nets by decomposing figures. Partner the student with a classmate to practice decomposing shapes into familiar figures to create nets. Ask the student to identify the faces, edges, and vertices of the threedimensional figure that connect to create the net.
Have the student create a net of a given solid that is large enough to cut out and fold. Have the student create the net labeling all dimensions as given in the original solid. Allow the student to cut out and fold the net in order to check its accuracy.
Consider implementing CPALMS activity Decomposing 3D Shapes (ID 13187) or an activity from the National Council of Teachers of Mathematics called Fishing for the Best Prism, http://illuminations.nctm.org/Lesson.aspx?id=2911, to create nets of rectangular prisms in context. 
Making Progress 
Misconception/Error The student does not adequately describe the dimensions of the shapes composing the net. 
Examples of Student Work at this Level The student can identify the composing shapes and draw the net of the pyramid, but:
 Does not label any of the dimensions for the square base or triangles.
 Makes one or more errors labeling the dimensions.
 Does not indicate the unit of measure.

Questions Eliciting Thinking How can you verify that the picture you have drawn represents the square pyramid?
Can you identify the measurements of the base and height of each shape in the net?
Did you label the units in your diagram? 
Instructional Implications Ask the student to label the lengths of each edge of the original threedimensional figure on the worksheet. Guide the student to look for parallel edges that have the same length. Then ask the student to locate each face of the solid in the net and to compare the dimensions originally shown to those now written on the solid. Ask the student to revise any dimensions that appear to have been written in error. Provide assistance to the student, as needed.
Provide additional opportunities for the student to decompose threedimensional figures into nets composed of familiar twodimensional shapes. Consider implementing the MFAS task Skateboard Ramp (6.G.1.4). 
Got It 
Misconception/Error The student provides complete and correct responses to all components of the task. 
Examples of Student Work at this Level The student accurately draws a net of the square pyramid and labels each figure using specific dimensions.

Questions Eliciting Thinking Is there more than one way to draw the net of the pyramid?
How could you use the net to find the surface area of the pyramid? 
Instructional Implications Challenge the student to represent the square pyramid using a different net with the dimensions labeled. Ask the student to use the net to determine the surface area of the pyramid.
Consider implementing the MFAS task Skateboard Ramp (6.G.1.4).
