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

Materials Needed

• Paper and crayons or colored pencils
• Small objects to count, such as blocks, buttons, toy animals, or snacks
• Number cards or a handwritten card showing the numeral 1
• Paper or sticky notes
• A small bag or box
• Optional: children’s book about numbers or a song about counting

Learning Objectives

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

• Recognize and name the numeral 1.
• Count one object accurately.
• Show that the word one means a single object.
• Trace, write, or form the numeral 1.
• Identify examples of “one” in everyday life.

Success Criteria

The learner is successful when they can:

• Point to the numeral 1 when shown several numerals.
• Give exactly one object when asked.
• Match the numeral 1 with a group containing one object.
• Make or write a recognizable 1.

Introduction: The One-Object Mystery

Hook: Place several objects in a bag, but secretly choose only one special object. Say, “Today we are number detectives. Can you discover how many special objects are hiding in my hand?” Reveal one object.

Ask:

• “How many objects do you see?”
• “What word tells us that there is only one?”
• “Can you find one object near you?”

Tell the learner: “Today we will explore the number 1. We will find it, count it, build it, and write it.”

Body of the Lesson

Part 1: I Do — Meet the Number 1

Show the learner the numeral card with 1. Say, “This is the numeral one. The numeral is the written symbol we use for the number one.”

Place one block beside the numeral card. Touch the block once and say, “One.” Then point to the numeral and say, “This shows one.”

Model the difference between one and more than one:

• Hold up one toy and say, “One toy.”
• Hold up two toys and say, “This is more than one.”
• Return to one toy and say, “One means a single object.”

Quick Check: Show groups of one, two, and three objects. Ask, “Which group has one object?” Invite the learner to explain how they know.

Part 2: We Do — One or More?

Place different groups of objects on a table. Mix groups containing one, two, and three objects.

Work together through these steps:

1. Look at one group.
2. Touch each object while counting.
3. Decide whether the group has one object.
4. Place the numeral 1 next to groups containing exactly one object.

Use think-pair-share if another person is available. The learner first thinks silently, explains their answer to a partner or stuffed animal, and then shares the answer aloud.

Sample Questions:

• “Does this group have one object? How do you know?”
• “What happens if I add another object?”
• “Can you make a group with exactly one object?”

Part 3: We Do — Number 1 Movement Game

Call out a movement, and have the learner perform it exactly one time:

• Clap one time.
• Jump one time.
• Tap the table one time.
• Spin one time.
• Give one high-five.

After each action, ask, “How many times did you do it?” Emphasize that one action means the action happened a single time.

Part 4: You Do — Number Detective Hunt

Invite the learner to search safely around the home for examples of one. They may find:

• One front door
• One refrigerator
• One favorite stuffed animal
• One spoon
• One family pet or plant

For each discovery, the learner should say, “I found one ______.” They may draw the objects or place a sticky note labeled 1 beside them.

Part 5: You Do — Build and Write the Number 1

Demonstrate how to form the numeral 1:

1. Start near the top.
2. Make a short slanted line down.
3. Make a straight line down.
4. Add a small base line if desired.

Let the learner practice using one or more of these methods:

• Trace a large printed 1.
• Write 1 with a crayon or pencil.
• Form 1 with blocks, craft sticks, or play dough.
• Draw one object and write 1 beside it.

Give specific feedback, such as, “You started at the top and made one clear line down.”

Creative Choice Activity

Choose one project:

• One-Page Art: Draw one large object and decorate the page with the numeral 1.
• One Treasure Box: Put exactly one special item in a box and explain why it is special.
• One-Character Story: Create a short story about one animal, person, or imaginary character.
• Number 1 Collage: Find or draw pictures of things that appear one at a time and place them around a large numeral 1.

Assessment

Formative Assessment

During the lesson, check whether the learner can:

• Identify the numeral 1.
• Count one object without adding or skipping objects.
• Separate a group of one from groups of more than one.
• Follow directions involving one action.

Summative Demonstration

Ask the learner to complete the following independently:

1. Point to the numeral 1 among three different numerals.
2. Give you exactly one object.
3. Draw or build a group containing one object.
4. Match the group with the numeral 1.
5. Write or form the numeral 1.

Suggested benchmark: The learner meets the objective by completing at least four of the five tasks accurately. Repeat the activities with new objects if additional practice is needed.

Differentiation and Adaptations

For Learners Who Need More Support

• Use large, brightly colored objects and work with only one and two objects at first.
• Guide the learner’s hand while counting and touching one object.
• Use physical prompts, such as holding up one finger while saying “one.”
• Provide a dotted-line numeral for tracing.
• Repeat the same routine with different objects and movements.

For Learners Ready for More Challenge

• Ask the learner to find the numeral 1 in books, labels, or calendars.
• Compare one with zero, two, and three.
• Practice writing the word one.
• Create a simple story problem involving one object, such as, “One bird is in the tree.”
• Ask the learner to explain how they know a group contains exactly one object.

Flexible Learning Options

• Hands-on: Use household objects, blocks, or play dough.
• Digital: Use a drawing app or digital number-tracing activity.
• Auditory: Sing a counting song and pause on the word “one.”
• Movement-based: Use one-step actions such as one clap or one jump.
• Independent: Complete the number hunt and art project alone.

Conclusion: Tell What We Learned

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

• “The numeral that means one is ____.”
• “One means ____ object.”
• “I can show one by ____.”
• “One thing I found today was ____.”

Hold up the numeral 1 and say, “Today we learned that one means a single object. We practiced finding one, counting one, moving one time, and writing the numeral 1.”

Optional Follow-Up

Throughout the day, invite the learner to notice and record three examples of one. At the end of the day, review the examples and ask, “How did you know each example showed one?”
