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

SIX

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.

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

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
