One-of-a-Kind Adventure: Learning the Number 1

Materials Needed

• Paper and crayons or markers
• One small toy, button, block, or household object
• Number cards or a handwritten card showing 1
• Several groups of objects containing different amounts, such as 1, 2, and 3
• Optional: a picture book about counting
• Optional: a tablet or computer for a short counting song

Learning Objectives

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

• Identify the numeral 1.
• Count one object accurately.
• Match the numeral 1 to a group containing one object.
• Trace and write the numeral 1.
• Find examples of “one” in everyday life.

Success Criteria

The learner is successful when they can:

• Point to the number 1 when shown several numerals.
• Give or select exactly one object.
• Match 1 with a group of one object.
• Write or trace a recognizable 1.

Introduction: The One-Object Mystery

Hook: Place one special object in front of the learner. Say, “I found a mystery collection! How many objects are here?” Encourage the learner to touch or point to the object while counting.

Explain: “Today we are going on an adventure to learn about the number one. One means a single object—just one!”

Tell the learner what they will do: “We will find one object, recognize the number 1, practice writing it, and search for things that come in ones.”

Body

1. I Do: Model the Meaning of One

Hold up one object and say slowly, “One.” Touch the object once as you say the word.

Show the numeral 1 and say, “This is the numeral 1. It tells us there is one object.”

Model the following:

1. Place one block on the table.
2. Touch it once.
3. Say, “There is one block.”
4. Place the number card 1 beside it.

Quick check: Ask, “How many blocks are there?” Listen for “one.” If needed, guide the learner to touch the block once while saying “one.”

2. We Do: One or More Than One?

Make several small groups of objects. Include a group with one object and groups with two or three objects.

Invite the learner to examine each group. Ask:

• “Which group has one object?”
• “Can you touch each object and count it?”
• “Which group does not show one?”

Play a movement version:

• Say “one clap,” and clap once together.
• Say “one jump,” and jump once together.
• Say “one tap,” and tap the table once together.

Think-and-share: Ask the learner to name one thing they can see. For example, “I see one chair.” If working with more than one learner, have partners take turns finding and naming one object.

3. We Do: Number 1 Treasure Hunt

Search the room or home together for things that appear as one. Possible examples include:

• One door handle
• One lamp
• One nose
• One sun in a drawing
• One book selected from a shelf

Each time the learner finds an example, ask them to say, “I found one _____.” They may draw one of their discoveries on paper.

4. I Do: Model Writing the Numeral 1

Use your finger to draw a large 1 in the air. Say:

“Start at the top. Slant down. Then make a short line at the bottom.”

Model writing the numeral on paper. Keep the demonstration large and slow. You may also make a 1 using a finger in sand, flour, or a tray of rice.

5. You Do: Number 1 Practice

Invite the learner to complete the following activities:

1. Build it: Use one block, one toy, or one craft item to make a small creation.
2. Match it: Place the number card 1 beside a group containing one object.
3. Trace it: Trace several large dotted numerals 1.
4. Write it: Write the numeral 1 independently several times.
5. Draw it: Draw one favorite object and label the picture with 1.

Offer a choice: “Would you like to practice with crayons, in the air, on paper, or in a tray of rice?”

6. Fun Application: The One-of-a-Kind Café

Pretend to run a café. The customer may order only one item at a time.

Give directions such as:

• “Please serve me one spoon.”
• “Please give me one pretend cookie.”
• “Please place one cup on the table.”

Switch roles so the learner becomes the café owner. Encourage complete sentences such as, “Here is one cup.”

Formative assessment: Notice whether the learner consistently selects exactly one item. Give specific feedback: “You counted carefully and chose one spoon.”

Differentiation and Support

For a Learner Who Needs More Support

• Use only two choices at a time: one object and a group with two objects.
• Use large objects that are easy to see and touch.
• Count slowly while touching the object once.
• Provide a dotted numeral 1 or hand-over-hand guidance if appropriate.
• Repeat the same activities over several short sessions.

For a Learner Ready for a Challenge

• Ask the learner to make groups containing one object and explain their choices.
• Invite them to find the numeral 1 in books, labels, or a calendar.
• Ask, “What happens if we add one more?” and introduce the idea that one plus one makes two.
• Have the learner create a page titled “One Things I See” with drawings and labels.

Assessment

Formative Assessment During the Lesson

• Ask the learner to point to the numeral 1.
• Ask the learner to give you exactly one object.
• Show groups of objects and ask which group contains one.
• Observe whether the learner touches each object once while counting.
• Check the learner’s tracing and writing attempts.

Summative Demonstration

Ask the learner to complete this “Number 1 Challenge” independently:

1. Find the numeral 1 among three different numerals.
2. Place exactly one object beside it.
3. Say, “One.”
4. Write the numeral 1.
5. Tell or draw one thing they found during the treasure hunt.

Suggested mastery goal: The learner completes at least four of the five tasks correctly, with support reduced as much as possible.

Conclusion: Tell What We Learned

Review the lesson by asking:

• “What number did we learn today?”
• “What does one mean?”
• “Can you show me one object?”
• “How do we write the number 1?”

Have the learner hold up one finger and say, “One means a single object.” Finish with one celebratory clap, one jump, or one high-five.

Optional Follow-Up Activities

• Read a counting book and pause whenever the number one appears.
• Make a collage using one large shape on a piece of paper.
• Take a short walk and photograph or draw things that appear one at a time.
• Place the number 1 on the refrigerator and look for it during the day.
