TRANSCRIPT
How do you tell the difference between a pentagon and a hexagon?
How do you know if a pentagon is regular or irregular?
Which is which?
In this lesson you will learn to identify shapes by looking at
the number of sides and angles that a shape has.

Let’s ReviewCore Lesson
Polygons are named for the number of sides AND angles they possess.
3 - Tri
4 - Quad
5 - Pent
6 - Hex
7 - Hept
8 - Oct
Let’s ReviewCore Lesson
When the sides and angles of a polygon are all exactly congruent, that shape is called
“regular.”
Regular Irregular
Let’s ReviewA Common Mistake
It’s easy to forget the different names of shapes.
5 – Pent(The Pentagon)
8 – Oct(octopus)
6 – Hex

Let’s ReviewCore Lesson
Name this shape. Tell whether it is regular or irregular.
Irregular Triangle
Let’s ReviewCore Lesson
Name this shape. Tell whether it is regular or irregular.
Irregular Hexagon
Let’s ReviewCore Lesson
Tell which of these shapes is a pentagon and which is a hexagon.
Determine whether the shape is regular or irregular.
Pentagon,Regular
Hexagon,Regular
In this lesson you have learned to identify shapes by looking at the number of sides and angles
that the shape has.
Let’s ReviewGuided Practice
Which of the following shapes are octagons?
Let’s ReviewExtension Activities
Draw at least 10 polygons. Name each polygon and tell whether or not it is regular.
Let’s ReviewExtension Activities
Describe a shape in writing. See if a friend can guess your shape based on the description.
Example:I am a polygon with 5 sides and angles. All of my sides are 3 inches long. What am I?
Answer: regular pentagon
Let’s ReviewQuick Quiz
Which of the following shapes can be classified as “regular”?
How do you know when a shape is a quadrilateral?
Lesson Slides Rubric
Use this rubric to ensure your lesson plan is great!
Math Rubric Criteria for Success Things to avoid
Storyline or Arc of the Lesson
There is a clear arc to the lesson. One slide leads naturally to the next so that there is a flow and a building of meaning
All the components of the lesson are there but they seem disconnected, as if the author wrote each without thinking about how they fit into the whole.
Hook Slide
The teacher poses a simple question that illicits the response, “yeah, I do wonder how that works…”
The question is short A relevant example is included when it is short and
further pulls the learner in The question mirrors what the student will learn,
then need to do later in the guided practice
The question seems formulaic, inauthentic, or overly “school-ish” (message: you have to learn this because you’re in school rather than, this is genuinely interesting)
The hook is overly-complicated and potentially confusing The question does not parallel the guided practice
questions
Objective Slide
The objective follows the form (you will learn X by doing Y)
Is concise and follows the form provided in the examples
Does not follow the form Is overly vague in describing either the X or the Y Is too long Is written for teachers but not students
Let’s Review
Reminds the student of how this lesson fits with other lessons (the lesson, however, should still be able to stand on its own)
Reminds the student of important vocabulary Is as concise as possible Uses visuals whenever possible
Is either too detailed or not detailed enough in connecting the lesson to other lessons
Leaves out important touch points Makes the lesson overly dependent on the other lessons
(student will be confused or feel like they’ve made a mistake, if they watch this lesson alone)
Common Mistake Points out a common mistake that students make Concisely explains the thought process that leads to
that mistake
Isn’t actually a mistake students make (too simple) Is confusing or vague
Modeling a Way of Looking at It
Clearly models a way to look at the standard Uses visuals as often as possible to show how the
way of looking works Is in “think aloud” format. The teacher is opening
up his/her thought process to the student Takes advantage of every opportunity to explain
why the math works the way it works Engages the learner by asking questions along the
way to build suspense Uses an an example to show the way in action Explains how this way of looking at it shows why
the common mistake (see above) is a mistake
Focuses on the algorhythm (or trick) instead of on showing a way of looking at the math
Fails to use visuals to show a way Fails to explain his/her thinking along the way. The
teacher effortlessly runs through the steps as if it’s all obvious and easy
Does not ask any questions along the way to pull the learner in
Misses opportunities to explain the why behind the math
Fails to explain why this way of looking at the math addresses the common mistake
Objective Review
Reviews the objective in a way which conveys, “we’ve come full cicle and now you see this objective with new eyes.”
Serves as a “let’s pull this all together” moment that helps organize the lesson in the learner’s mind
Creates abrupt feeling between the lesson and the reviewing (subtext: “we’re done with this lesson, let’s quickly bring it to a close.”)
Guided Practice Is at the same difficulty level modeled in the lesson Is connected to the initial hook question
Seem unrelated to the hook question Is at a different difficulty level than that modeled in the
lesson
Extension Activity Suggestions
Includes a suggestion for a struggling student who needs more opportunities for practice
Includes a suggestion for students who seem to get it but need more practice
Includes a suggestion for students who get it and are ready to be challenged further
Suggestions should clearly build from the approach in the core lesson
Does not include differentiation Does not thoughtfully connect or flow from the lesson Does not clearly build from the approach in the core
lesson Does not give a range of activities
Aesthetics
The slides use the correct colors (blue, green, red) in the correct sequence.
The slides use the correct fonts The slides use handwriting and the handwriting
appears as written in the right places The slides only use the headers/titles provided The slides use the provided visuals or include
visuals created by the author or LearnZillion The slides use animation, highlighting, and circling
to scaffold the learning, keeping the eye focused on what the teacher is introducing/explaining
The slides clean and uncluttered. The visuals and text do not exceed the maximum amount (see tutorial for example of maximum)
The slides use other colors or vary the order of the colors
The slides add new headers/titles that aren’t part of the template
The slides use clip art The slides are cluttered Animation is distracting and feels more like sizzle than
part of the steak
