The Power of One: How One Small Change Can Make a Big Difference

Materials Needed

• Paper or a notebook
• Pencil, colored pencils, or markers
• Timer or clock
• Small household objects, such as a cup, spoon, toy, or book
• Optional: calculator, tablet, or computer

Grade Level

Grade 4 homeschool

Estimated Time

45–60 minutes

Learning Objectives

By the end of the lesson, the learner will be able to:

• Explain how one small action can create a larger result.
• Identify a problem in everyday life and suggest one practical solution.
• Use addition, multiplication, or a simple table to predict how a small change could grow over time.
• Design and explain a creative “one small change” plan.

Success Criteria

The learner is successful when they can:

• Clearly describe the problem they want to solve.
• Suggest one realistic action.
• Show, with numbers or examples, how the action could make a difference.
• Explain why their idea would be useful.

Introduction: The One-Minute Challenge

Hook: Ask, “What could you accomplish if you improved something by just one small step each day?”

1. Give the learner one minute to tidy as many objects as possible or organize one small area.
2. Count the number of objects moved or organized.
3. Ask: “If you did the same thing every day for a week, how many objects would that be?”

Discuss possible answers. For example, if the learner organized 6 objects in one minute:

6 objects × 7 days = 42 objects

Tell the learner:

Today we will investigate how one small action can grow into a much bigger result. You will become a problem-solver and design your own “Power of One” plan.

Vocabulary

• Action: Something a person does.
• Impact: The effect or result of an action.
• Habit: Something a person does regularly.
• Predict: To make a careful guess about what may happen.
• Solution: An idea or action that helps solve a problem.

Body: I Do

Teacher or Adult Modeling

Explain the following example:

“Suppose I decide to read one extra page every night. One page may not seem like much, but after 7 nights I will have read 7 extra pages. After 4 weeks, I will have read about 28 extra pages.”

Model the calculation:

• 1 page each night × 7 nights = 7 pages each week
• 7 pages each week × 4 weeks = 28 pages in one month

Think aloud:

My small action is reading one extra page. The result is that I can finish more books or learn more information over time. My action is easy to repeat, so it could become a habit.

Quick Check

Ask the learner:

• What was the small action?
• What was the larger result?
• Which operation did we use to find the total?

Body: We Do

Activity 1: Small Action, Big Result

Work together to solve these examples. The learner may use drawings, repeated addition, multiplication, or a calculator.

1. If you save $1 each week, how much will you save in 8 weeks?
2. If you pick up 3 pieces of litter each day, how many pieces will you pick up in 10 days?
3. If you practice a musical instrument for 5 extra minutes each day, how many extra minutes will you practice in one week?

After each question, ask:

• What is the small action?
• How often does it happen?
• What is the total result?
• Would this action be easy or difficult to repeat? Why?

Activity 2: Think, Pair, Share—or Think, Talk, Share

Choose one everyday area:

• Keeping a room organized
• Taking care of pets
• Helping the environment
• Improving health
• Learning a skill
• Helping family members

The learner thinks of one small action and completes this sentence:

If I __________________ once each day or week, then __________________ might happen over time.

If working with a partner, share ideas and give one helpful suggestion. If working independently, explain the idea aloud to an adult, stuffed animal, or imaginary teammate.

Body: You Do

Project: Design a Power of One Plan

The learner creates a one-page plan for a small action that could make a positive difference.

The plan must include:

1. The problem: What could be improved?
2. My one small action: What will I do?
3. My prediction: What may happen after one week, one month, or one year?
4. My math: Show the result using numbers, a table, repeated addition, or multiplication.
5. My explanation: Why is this action useful?
6. A picture or symbol: Draw the action or its result.

Choice Board

The learner may choose one of these project formats:

• Create a colorful poster.
• Make a three-slide digital presentation.
• Record a one-minute explanation.
• Write a short “Power of One” story.
• Build a simple model using household materials.

Possible Project Ideas

• Read one extra page every night.
• Use one less disposable item each day.
• Put away one item immediately after using it.
• Learn one new word each day.
• Do one kind act each day.
• Practice one math fact for five minutes each day.
• Save one dollar, coin, or small amount of money regularly.

Formative Assessment

• Listen for accurate use of the words action, impact, habit, and solution.
• Check whether the learner selects the correct operation in the practice problems.
• Ask the learner to explain their thinking instead of only giving an answer.
• Use the question: “How does your number show that a small action can grow?”

Summative Assessment

Evaluate the Power of One Plan using this four-point checklist:

Differentiation

Support for Learners Who Need More Help

• Use smaller numbers, such as 1, 2, 5, or 10.
• Provide the sentence frame: “I will do ___ each day. In one week, that equals ___.”
• Allow the learner to draw groups instead of writing multiplication sentences.
• Complete the project orally with an adult acting as a recorder.
• Use a calendar and place one sticker on it for each completed action.

Extension for Advanced Learners

• Compare two different plans and decide which has the greater impact.
• Calculate the result over 30 days, 6 months, or 1 year.
• Create a table or line graph showing growth over time.
• Consider whether the action is realistic and explain possible challenges.
• Design a plan involving a group, such as a family or community.

Real-World Application

Explain that people use this kind of thinking in many real-life situations. Saving small amounts of money can build financial security. Practicing a little each day can improve a skill. Recycling one item, helping one person, or making one healthy choice can contribute to a larger positive change.

Conclusion: Recap and Reflection

Ask the learner to complete these statements:

• One small action can create a bigger result because __________________.
• The action I would like to try is __________________.
• My action could make a difference by __________________.
• The math I used to predict my result was __________________.

End with this challenge:

Choose your one small action and try it for seven days. Keep track of what you do, what changes, and how you feel. At the end of the week, decide whether your one small action made a difference.

Optional Follow-Up

After seven days, review the learner’s record. Discuss:

• Was the action easy to repeat?
• What result did you observe?
• Did anything unexpected happen?
• Would you continue, change, or replace the action?
