Introduction to Geometry
Geometry Foundations with Algebraic Expressions
Students explore geometry topics in connections with algebraic
expressions and equations.
GEOM.7A: Use one- and two-dimensional coordinate systems to
represent points, lines, rays, line segments, and figures.
Key Vocabulary: What key terms will my students need to understand?

Engage and Connect: How will I engage my students in learning? How
will I lead my students to mastery?

The teacher will project a slide of Kandinsky’s Composition VIII on the
board; students will look at the picture and list as many geometrical
objects as they can find in it.

We start off going over the concept of an undefined term. “Have you
ever come across a word you didn’t know and looked up its meaning in Projector
the dictionary? However, in that definition, there was another word
you didn’t know? When you looked up that one, the same thing
happened. If you continued the process, eventually, you would get to
a word that doesn’t have a specific definition, but can be understood
in context, like the word, ‘the.’’ I use this example to help students
relate to a word not having a definition. The three terms, point, line,
and plane, are building blocks for understanding geometry and can be
used to define other geometric terms.

of a point, line and plane.

Students write “Point,” “Line,” and “Plane” on the top inside section of for students
each tab. On the bottom section, students write a description of each
how to
term. Students are usually able to come up with their own descriptions make them,

based on prior knowledge. We go over their descriptions and add
paper
anything they may have left out.
In this section, students will create a graphic organizer to explain the
“undefined terms.” We then create a three-tab graphic organizer. On

Materials:
In this part of the lesson, students will read a passage, “What is
Geometry?” from the book, Timed Reading in Mathematics: Book 3 by
Glencoe/McGraw-Hill. This passage gives a good introduction to
Geometry. After they read, students answer reading comprehension
questions.
When the students finish answering the questions, we go over them. I
choose a student to read the question and their answer. Then we
discuss the validity of their answers. Another way to go over the
answers is to have the students write the letter of their answer on a
mini-whiteboard. By using the whiteboards, I am able to see each of
the students’ responses.
Exit Ticket:
What is Euclidean Geometry?
Differentiation: How will I scaffold and/or accelerate learning? For Whom? How will I
group my students?
Varied sources of problems, difficulty levels, open-ended questions
Accommodations/Modifications:
Zoom text, large print, read aloud. Use of multiple formats to present material and
gauge student understanding.
Homework:
Students will be asked to solve the following problems for homework:
