Each lesson consists of three parts, the **lesson
plan**, the **laboratory**, and the **solution**

** The lesson plan** **is designed for the
teacher** and consists of the following components:

- Lesson title with an optional introduction to
the topic.
- Existing knowledge that students are presumed to
have.
- The NCTM and/or the state strandards met by the lesson.
- The Learning objectives. The complexity of these
objectives will dictate the number of laboratories needed.
- Materials needed, if any.
- Suggested procedure
- Set attention getter
- Decide how to group the students, if a particular
method is recommended
- Assessment

- Optional review

The **laboratory **is designed for the
student and consists of:

- Lab title
- Team members’ names & file name
- Lab’s Goal(s)
- Investigation
- Consists of a guided procedure leading the
students through questions to investigate key properties, in every
stage of the construction, which propitiates the analysis of the
result under consideration.
- It should proceed through inquiry, and
take full advantage of the dynamic nature of this software promoting
as much as possible the
*“explore-discover-
conjecture-test-summarize”* model.
- Students should be asked to summarize in their
own words each property found.
- Further refining of these summaries
will contribute to improve their mathematical writing and to better
understand the properties.
- Whenever possible the labs should include
extensions designed to challenge the best students.
- Applications to real world situations
involving the property being study should precede or follow the
laboratory.

The **solution
****is** **designed for the teacher**; it aims to further clarify the
procedures and results that students are expected to find.
