Background/Preparation: 
Prior knowledge formula: Area = Length times Width Students should discover the following formula for finding the surface area of a rectangular prism: Math formula for the surface area of a rectangular prism: 2lh + 2lw + 2wh, or 2(lh + lw = wh) l = length; h = height; w = width 
As students enter the classroom, the teacher will hand each student a colored card. Students will be assigned to groups according to the color of the card. Students should be in groups of four. Before: (Activate prior knowledge) 3 to 5 minutes Handout a tchart for students to list and sort twodimensional and threedimensional examples. Show video on twodimensional and threedimensional examples. ( examples of 24 nets) During: (Actively engage students) The teacher give the students the two performance tasks:
Follow the steps to complete the performance task.

Attachments: **Some files will display in a new window. Others will prompt you to download. 
Assessment Strategies 
After: (Assessment) Performance Task III will be used to assess for enduring understanding. Rubric included on the Performance Task III card. In addition, a writing component is at the end of the Performance Task III card. 
Acceleration: 
Printable nets: 2D patterns for 3D shapes This interactive tool allows you to learn about various geometric solids and their properties. You can manipulate and color each shape to explore the number of faces, edges, and vertices. Writing Component: After students have completed Performance Task III, they can write message to their classmates and put their message in the boxes. 
Intervention: 
Video on 2D patterns and the 3D shapes they create. This is a Youtube video. If the school system blocks Youtube videos, the teacher may download the video for free at keepvid.com. Videos, worksheets, stories and songs to help Grade 5 to Grade 8 students learn how to draw and recognize nets for 3dimensional shapes.
