=Moving Towards Proof Activity= Sketchpad can offer the opportunity to explore proofs in various ways. Students can first construct the proof starting with the given information. They can then explore it using the dynamic features of Sketchpad, and then use this information to create a formalized written proof. This method can also be used to provide counterexamples. The following activity can be used to help students explore how to construct a proof starting with the given information.

__Directions__

 * 1) Find a partner
 * 2) Open the following file: [[file:Rhombus Proofs Exploration Student.gsp]]
 * 3) This file contains 7 pages. Each page has a statement. Your goal is to determine whether the given information is enough to create a rhombus. Remember, you are to create dynamic constructions. You will have to use a variety of options for your constructions. Helpful commands will be under "Construct" and "Transform".
 * 4) Use hide/show buttons to help explain how you created your constructions

__**Reflection**__

 * 1) Here is the solution file: [[file:Rhombus Proofs Exploration Solutions.gsp]]
 * 2) What advantages and challenges might occur with a construction activity?
 * 3) How might you change this activity for your class?
