Reflection: Connection to Prior Knowledge Surface Area of 3D Solids - Section 1: Do Now

 

After teaching this lesson, I thought about how it could be interesting and beneficial to students if the Do Now was more student centered.  Instead of giving students the 3 questions, next time I will have students create and pose their own questions to their group.  This would be a "Who am I" activity.  I will instruct students to write a prompt describing a polyhedron.  Then, they will take turns presenting these questions to their group to see if they're able to identify the polyhedron.

This activity would allow students to check one another's understanding of polyhedrons.  Also, it would encourage student discussion.

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.
