Lesson Plan

Animation Principles Outline

Students will apply core animation principles—timing, squash and stretch, and anticipation—through guided examples and hands-on exercises, demonstrating foundational skills in a 30-minute individual session.

Understanding these principles helps students craft more engaging, dynamic animations and builds essential skills for future media & design projects.

Audience

10th Grade Students

Time

30 minutes

Approach

Guided examples followed by targeted practice

Materials

  • The 12 Principles of Animation, - Instructor’s Step-by-Step Guide, - Pose-Flip Exercise Worksheet, and - Reflection on Motion Cool-Down

Prep

Review and Setup

5 minutes

  • Review The 12 Principles of Animation to familiarize yourself with example visuals and talking points.
  • Skim the Instructor’s Step-by-Step Guide to plan pacing.
  • Prepare blank paper or digital drawing tool for the Pose-Flip Exercise Worksheet.
  • Have the Reflection on Motion Cool-Down prompt ready for distribution.

Step 1

Introduction to Principles

5 minutes

  • Briefly define timing, squash and stretch, and anticipation.
  • Use slides 1–5 from The 12 Principles of Animation to show visual examples.
  • Ask the student to note one real-world example of each principle.

Step 2

Guided Demonstration

10 minutes

  • Demonstrate a simple bouncing ball animation emphasizing squash and stretch and timing (slides 6–9).
  • Show how anticipation (slide 10) adds clarity to motion.
  • Pause to ask the student to describe what changes when timing is faster or slower.

Step 3

Pose-Flip Practice

10 minutes

  • Distribute the Pose-Flip Exercise Worksheet.
  • Instruct the student to sketch two poses for a simple action (e.g., jump) and flip between them to observe motion.
  • Guide them to apply squash and stretch in their sketches and note timing on each frame.

Step 4

Reflection and Cool-Down

5 minutes

  • Provide the Reflection on Motion Cool-Down prompt.
  • Ask the student to write or discuss:
    • Which principle was most challenging to apply?
    • How might they use anticipation in a longer animation?
  • Summarize key takeaways and next steps for further practice.

Slide Deck

The 12 Principles of Animation

Today’s Focus:
• Timing
• Squash & Stretch
• Anticipation

Welcome the student and introduce the session. Explain that although these are called the “12 Principles,” today we’ll focus on timing, squash & stretch, and anticipation. Point out how mastering these three builds a strong foundation.

What Are the 12 Principles?

  1. Squash & Stretch
  2. Anticipation
  3. Staging
  4. Straight Ahead & Pose to Pose
  5. Follow Through & Overlapping Action
  6. Slow In & Slow Out
  7. Arc
  8. Secondary Action
  9. Timing
  10. Exaggeration
  11. Solid Drawing
  12. Appeal

Briefly list all 12 principles so the student sees the big picture. Highlight our three in red or bold on the slide.

Principle: Timing

• “The number of frames for a given action”
• Controls speed, weight, and mood
• More frames = slower motion; fewer = faster

Define timing: the spacing of frames to convey speed and weight. Emphasize that good timing makes motion feel natural.

Timing Examples

• Fast vs. slow blinking eyelid
• Horse gallop: quick vs. languid pacing
• How does timing affect emotion?

Show two short animations or image sequences: a fast blink and a slow blink. Ask the student which feels heavy vs. light.

Principle: Squash & Stretch

• Deforming shape to show weight and flexibility
• Squash = flattening; Stretch = elongating
• Maintains volume for realism

Explain squash & stretch as the essence of life in animation. Note that volumes should remain consistent.

Squash & Stretch Examples

• Bouncing ball:

  • Contact: squash
  • Rising/falling: stretch
    • Character faces, limbs can squash/stretch too

Display a bouncing ball in its neutral, squashed, and stretched states. Point out the contact and apex frames.

Principle: Anticipation

• Small movement before main action
• Signals what’s coming next
• Example: wind-up before a pitch or crouch before a jump

Introduce anticipation as a preparatory action. Stress that it guides viewer expectations and adds clarity.

Anticipation Examples

• Throwing a punch:

  • With wind-up (clear)
  • Without wind-up (confusing)
    • Jump start: crouch vs. no crouch

Use side-by-side frame sequences: a character jumping with and without anticipation. Ask the student which reads better.

Bouncing Ball Breakdown

Key Frames:

  1. Contact (squash)
  2. Ascent (stretch)
  3. Apex (neutral)
  4. Descent (stretch)
  5. Contact (squash)

Frame spacing: 1–2 quick, 2–3 slow, etc.

Walk through a 5-frame bouncing ball that uses timing and squash & stretch together. Show how frame spacing changes impact speed.

Putting It All Together

Practice Tips:
• Flip two poses rapidly to test timing
• Apply squash & stretch to emphasize weight
• Add a small anticipation before each major action

Next: Complete the Pose-Flip Exercise Worksheet

Summarize how the three principles work together. Prompt the student to start the Pose-Flip Exercise next.

Instructor’s Step-by-Step Guide

Introduction to Principles (5 minutes)

Teacher (T): “Hi there! Today we’re going to dive into three of the most powerful animation principles—timing, squash & stretch, and anticipation. Mastering these will make your animations feel alive and believable.”

T (show The 12 Principles of Animation – Slide 1): “Here’s our focus for today. Let’s flip to the next slide to see all 12 principles at a glance.”

T (show Slide 2): “See how timing, squash & stretch, and anticipation fit into the bigger picture? Let’s find a real-world example for each.”

T (prompt): “First, squash & stretch—can you think of something you’ve seen flatten or elongate in real life? Maybe a water balloon? Share your example.”


T (listen, then follow up): “Great! That flattening really shows weight. Next, timing—where have you noticed a motion go super fast or creep along slowly? What feeling did that give you?”


T (after response): “Perfect. Finally, anticipation—think of a pitcher winding up before a throw. Why does that small movement help you understand what’s coming?”





Guided Demonstration (10 minutes)

T: “Let’s see these in action with a simple bouncing ball. We’ll focus on squash & stretch and timing, then add anticipation.”

T (show Slide 5: Squash & Stretch Examples): “Notice at the contact point the ball flattens—squash—and as it soars, it elongates—stretch. Both keep the same volume but convey flexibility and weight.”

T (show Slide 9: Bouncing Ball Breakdown): “Here’s a five-frame breakdown. Watch the spacing: frames 1–2 are quick for the pop off the ground, frames 2–3 slow at the apex. What mood or energy does this timing give the ball?”


T (after student answers): “Exactly—that slower midair pause feels more pronounced, like it’s floating. Now, let’s add anticipation.”

T (show Slide 6: Principle: Anticipation & Slide 7: Anticipation Examples): “See how a small crouch before the jump cues our eye? Which sequence reads clearer, the one with anticipation or without? Why?”


Pose-Flip Practice (10 minutes)

T: “Time to try it yourself. Here’s the Pose-Flip Exercise Worksheet.”

T (hand over worksheet): “In the left box (Pose A), sketch the crouch before a jump—exaggerate a squash in the legs or body. In the right box (Pose B), draw the stretch at the height of the jump.”

T: “When you’re done, flip quickly between the two sketches to test your timing. Think about how many frames you’d insert between them if this were a full animation.”

T (circulate, observe, and prompt): “Nice crouch! Want to push the squash further? How about stretching the body even more in Pose B to emphasize height?”





Reflection and Cool-Down (5 minutes)

T: “Great work—let’s reflect. Here’s the Reflection on Motion Cool-Down prompt.”

T (provide prompt): “Take a minute to write or talk about these questions:

  1. Which principle—timing, squash & stretch, or anticipation—felt most challenging?
  2. How might you use anticipation to improve a longer animation sequence?”










T (after sharing): “Thanks for sharing your thoughts. Remember, tweaking frame spacing and exaggerating your squash & stretch takes practice. Next time, try applying these principles to a walk cycle or a character action. You’re off to a fantastic start!”
