## Reflection: Shared Expectations Creating a Robot (2 Days) - Section 3: Robot Project

On day 1, the students discussed some of the particulars of setting up their robot.  They talked about who would be responsible for each part of the process.  They also talked about the measurements they would use so that their robots would turn out somewhat symmetrical.  On day 1 the students were able to make most of their nets and determine the surface area.  In order to keep their projects together, I had the students place all of their materials in a plastic grocery bag with their names on them.  This way project materials would not be smashed in lockers or lost in the hall way.

Day 1: using nets to create our robot

On day 2, the students finished creating the nets and calculating the surface area.  At this time, the student needed to tell me how much foil was needed to cover their robot.  We started by having the students wrap the robot parts like a present.  This wasted too much foil. I then had them trace the faces on the robot and cut and paste each piece on separately.  This worked out much better and much more accurate. Students were able to use some teamwork strategies by having one student cut and trace while the other one taped the foil on the robot.

Day 2: covering our robot

Although this took some of my students longer than 2 days to finish, it was well worth it.  For the students that did not finish on time, I had them come in during my enrichment period to get the job done.  It was more important for me to have them finish, then turn in something that did not make them proud.

###### 3D Figures and Nets
Big Idea: Students explore cube nets in an effort to understand what properties are common to all nets that form a cube. Students work hands-on with nets and are then pushed to use their experience to visually determine whether other nets will form a given figures.
