DE Lesson Plan
Web 2.0 Lesson Plan
1. Title: Pythagorean
Theorem: What’s Your Angle Pythagoras?
2. Grade
Level/Subject: 8th Grade Math
3. Prerequisite
Knowledge: Perfect vs Nonperfect Square Roots; Simplifying and Estimating Radicals;
Solving two-step equations; Order of Operations (PEMDAS); Integer Rules
4. Approximate time
for the entire lesson: 1.5 weeks
5. Learning Objectives: The purpose of this lesson is for students to discover and formalize the
Pythagorean Theorem by investigating the relationship between the areas of the
squares constructed on each side of a right triangle. Students will also apply the Pythagorean Theorem to find
missing lengths in a right triangle and solve equations involving square roots
as it relates to the Pythagorean Theorem. Students will use prior knowledge of
square roots to make connections between the concepts. By the end of the week,
students will be able to demonstrate an enduring understanding of using and
applying the Pythagorean Theorem.
6. Relevant Standards:
M8N1: Students will understand
different representations of numbers including square roots, exponents, and
scientific notation.
M8G2: Students will understand and use the
Pythagorean Theorem.
7. The Web 2.0 tool
chosen to deliver the lesson: blog and wiki (PBworks)
8. Assessment to measure learning outcomes using this lesson: Learning task from Georgia Department of Education, “Comparing TVs” along with 5 real world based Pythagorean Theorem problems.

What is Web 2.0?
Web 2.0
Web 2.0 is an upgraded version of Web 1.0. It is known as the second generation of
web-based applications and services.
Web 2.0 makes it easy for users to create, distribute and share content,
often collaboratively. Web 2.0
tools include blogs, wikis, and social networking tools and applications. Web 2.0 allows digital information to
be created, shared, stored, distributed, and manipulated. One of the biggest benefits of using
Web 2.0 tools is that they are less expensive than traditional software; in
fact, in many cases they are free.
For example, Google spreadsheets is a spreadsheet tool that is very
similar to Microsoft Excel; however the benefits are that it is free, it’s
web-based so there is no need to install software (freeing up computer memory
space), and it’s collaborative so multiple users can work on the spreadsheet at
the same time. Another benefit is
that Web 2.0 is web-based so data can be accessed from anywhere.
I believe that Web 2.0 technologies can be used to change
the face of education. Because we
are teaching digital natives, people who were born during or after the
introduction of digital technology, educators can no longer teach in a
traditional manner (lecture based and teacher focused). Teachers must find a
way to keep today’s generation of students engaged in learning and Web 2.0
technologies are a great tool for student focused learning. My initial thoughts and concerns about
integrating Web 2.0 tools, as a strategy for teaching is digital access. In my school, we have 2 computer labs
with a class set of computers; however they may not always be available to use
when I need them. We also have a
mobile laptop cart; however the laptops and Internet functions are extremely
slow. In many instances, they get
stuck or simply shut down in the middle of lessons. We also don’t have wireless Internet service in my building
so allowing students to bring in their own laptops would pose a problem as
well. I also fear that not all of
my students will have Internet access at home and those that do (which will be
the majority) will not take the initiative to log in and learn from home.
