The Amazing Number 1: Counting, Creating, and Finding One

Materials Needed

• Paper or a small whiteboard
• Pencil, crayons, or washable markers
• 10–20 small objects, such as blocks, buttons, toy animals, or coins
• Number cards from 0 to 10, handmade or printed
• One favorite toy or household object
• Optional: dice, tablet/computer, and a short counting song

Learning Objectives

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

• Recognize and name the numeral 1.
• Count out exactly one object when asked.
• Write the numeral 1 using correct formation.
• Explain that 1 means “one object” or “a single object.”
• Find examples of one object in everyday life.

Success Criteria

I can:

• Point to the number 1.
• Give or select one object.
• Write the number 1 at least three times.
• Tell or show an example of something that comes in a group of one.

Introduction: The Mystery of One

Hook: Place several objects on a table, but secretly choose one favorite object to hold behind your back.

Say: “I have a mystery object. I am holding just one object. How many objects am I holding?” Let the learner guess, then reveal the object.

Explain: “Today we are going to explore the number 1. The number 1 tells us that there is one object—not zero, and not two.”

Tell learners what they will learn: “We will find the number 1, count one object, write 1, and go on a one-object treasure hunt.”

Body: Learn and Practice

Part 1: I Do — Meet the Number 1

1. Show the numeral card 1.
2. Say: “This is the number 1. It is called one.”
3. Hold up one finger and say, “I have one finger up.”
4. Place one block on the table and count slowly: “One.”
5. Draw the numeral 1 in the air while saying: “Start at the top, pull straight down.”

Quick check: Ask:

• “What number is this?”
• “How many blocks are on the table?”
• “Can you show me one finger?”

Part 2: We Do — Find One

Place groups of objects on the table: one button, two blocks, three crayons, and no objects in another space.

Work together to identify the group with one object.

1. Point to one group at a time.
2. Count the objects aloud together.
3. Ask the learner to place the number 1 card beside the group with one object.
4. Mix the groups and repeat the activity.

Think-pair-share alternative: If another person is available, have the learner explain to a partner which group has one object and how they know. For homeschool use, the learner can explain the answer to a toy, stuffed animal, or adult.

Formative assessment: Show two groups—one with one object and one with several objects. Ask, “Which group shows one? How do you know?” Listen for the learner to count or explain that only one object is present.

Part 3: We Do — Number 1 Movement Game

Call out an action and the number of times to do it:

• Clap one time.
• Jump one time.
• Spin one time.
• Tap your head one time.

After each action, ask: “How many times did we do it?” Encourage the learner to answer, “One.”

Part 4: I Do, Then You Do — Writing the Number 1

Model writing the number 1 on paper or a whiteboard:

1. Start at the top.
2. Draw a straight line down.
3. Add a small slanted line at the top if that is the style being taught.

Have the learner practice using several methods:

• Trace a large numeral 1 with a finger.
• Draw a 1 in the air.
• Write 1 in sand, rice, or flour on a tray.
• Write three numerals 1 on paper.

Give specific feedback, such as: “Your line starts at the top and goes down. That makes it easy to recognize as 1.”

Part 5: You Do — One-Object Treasure Hunt

Invite the learner to search the home for objects that come in groups of one.

Instructions:

1. Choose one safe area of the home.
2. Find five examples of one object.
3. Bring each example to a checking spot or point to it without moving it.
4. For each item, say: “I found one _____.”

Possible examples include one lamp, one door in a room, one television, one pet, or one shoe placed by itself.

Choice and creativity: The learner may draw the five objects instead of collecting them. They may also create a “museum of one” by placing five single objects in a row.

Part 6: Creative Challenge — Make a Picture of One

Ask the learner to create a picture that includes exactly one main object, such as:

• One sun
• One tree
• One balloon
• One animal
• One house

The learner should write the numeral 1 somewhere in the picture and explain: “My picture has one _____.”

Real-World Connection

Explain that people use the number 1 every day. Examples include:

• Choosing one snack
• Reading page 1 of a book
• Using one key to open a lock
• Taking one step at a time
• Waiting for one turn in a game

Ask: “Where might you use the number 1 today?”

Conclusion: Tell What We Learned

Review the lesson by asking the learner to complete these sentences:

• “The numeral for one is _____.”
• “When I see one object, I can count _____.”
• “To write 1, I start at the _____ and draw down.”
• “One example of something I found is _____.”

Finish with a short chant:

“One means one, that’s what we say!
One little object starts our day!”

Assessment

Formative Assessment

• Observe whether the learner identifies the numeral 1.
• Ask the learner to select exactly one object from a group.
• Listen for accurate counting during the movement game.
• Check the learner’s number formation during writing practice.

Summative Demonstration

Ask the learner to complete all four tasks independently:

1. Point to the numeral 1 among three number cards.
2. Give you exactly one object.
3. Write the numeral 1 three times.
4. Show or name one example of an object found at home.

Suggested benchmark: The learner completes at least three of the four tasks correctly, with support provided for any remaining task.

Differentiation and Adaptations

For Learners Who Need More Support

• Use larger objects and groups of only one or two objects.
• Count aloud together while touching the object.
• Use hand-over-hand guidance for forming the numeral 1 if appropriate.
• Provide a dotted-line numeral 1 to trace.
• Repeat the lesson in short five-minute activities throughout the day.

For Learners Ready for an Extension

• Compare 1 with 0 and 2 using objects.
• Find the numeral 1 in a book, calendar, clock, or digital game.
• Write a sentence such as, “I have one red ball.”
• Create a number story: “There was one bird. Then one more bird arrived. How many birds are there now?”
• Look for the number 1 in the community on signs, addresses, or house numbers.

Optional Follow-Up Activity

During the next day, ask the learner to keep a “One Journal.” Each day, they draw one object, write the numeral 1, and label the picture. After five days, review the journal and have the learner explain how every page shows one.
