Lesson Overview

Age/Grade: First grade homeschool

Suggested time: 30–40 minutes

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 a group of one using objects, drawings, or fingers.
• Write the numeral 1 with correct formation.
• Identify real-life examples of “one.”

Success Criteria

I can:

• Point to the number 1 when I see it.

Introduction: Hook and Objectives

Number Detective Challenge

Say: “Today you are a number detective! Your mission is to find things that come in groups of one.”

Invite the learner to look around and find three examples of one object, such as:

• One nose
• One chair being used
• One pencil in a hand
• One favorite toy

Ask:

• “How many objects are in each group?”
• “What number tells us there is just one?”

Explain: “Today we will learn about the number 1. One means a single object—not two, not three, but just one.”

Body

Part 1: I Do—Modeling the Number 1

Place one block in front of the learner. Touch it and say slowly:

“One block. There is one block.”

Show the numeral card labeled 1 and say:

“This is the numeral 1. We use it to show one object.”

Model writing the number:

1. Start at the top.
2. Make a short slanted line down.
3. Finish with a straight line down.

Say: “The number 1 looks like a straight line with a little beginning line.”

Quick Check

Show the learner the number cards 1 and 2. Ask:

• “Which card shows one?”
• “How do you know?”

Part 2: We Do—Build a Group of One

Place several objects on the table. Work together to make groups.

1. Ask the learner to place one block in a small group.
2. Have the learner touch the block and count: “One.”
3. Place the number card 1 next to the block.
4. Repeat with different objects, such as one button, one toy, or one crayon.

Use the sentence frame:

“I have one ______.”

Think-Pair-Share Alternative

If another person is available, ask the learner to think of one object, tell a partner, and explain why the group contains one. For homeschool practice, the learner can tell a stuffed animal or explain the answer to the adult.

Formative Assessment

Place two groups on the table: one group with one object and another group with two or three objects. Ask:

“Point to the group that shows one. How can you prove it?”

Part 3: We Do—Number 1 Movement Game

Play “Do One!” Give directions such as:

• “Clap one time.”
• “Jump one time.”
• “Tap your head one time.”
• “Take one step.”

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

For an added challenge, sometimes give an incorrect direction, such as “Clap two times,” and ask the learner to explain whether the direction matches the number 1.

Part 4: You Do—Number 1 Treasure Hunt

Invite the learner to find five examples of one around the home. The examples may be objects, pictures, or natural items.

For each discovery, the learner should:

1. Point to the object.
2. Say its name.
3. Say, “I found one ______.”
4. Make a tally mark or draw the object on paper.

Possible examples include one spoon, one plant, one clock, or one pet.

Part 5: You Do—Draw and Write

Ask the learner to complete the following page on paper:

1. Draw one large star.
2. Color the star.
3. Write the number 1 beside the star.
4. Practice writing the number 1 five times.

As the learner writes, remind them to start at the top and move downward. Praise effort and offer gentle feedback about starting position, direction, and size.

Creative Choice Activity

Let the learner choose one activity:

• One-Object Sculpture: Build a picture using one block, one toy, or one piece of craft material.
• Number 1 Story: Tell or draw a story about one character finding one special object.
• Snack Math: Place one snack on a plate and describe it using the sentence “There is one ______.”
• Number 1 Song: Make up a short song or cheer that repeats the word “one.”

Formative Assessment Questions

• “What number means a single object?”
• “How many objects are in this group?”
• “Can you give me one block?”
• “Which card shows one?”
• “Show me one finger.”
• “How do you know this group has one object?”

Summative Assessment: Show What You Know

Give the learner the following five-part challenge:

1. Circle the numeral 1 from a group of numerals.
2. Give the adult exactly one object.
3. Draw one object.
4. Write the numeral 1 independently.
5. Give one example of something that comes in a group of one.

Simple Scoring Guide

• 4–5 successful tasks: Secure understanding
• 2–3 successful tasks: Developing understanding; provide more practice
• 0–1 successful tasks: Reteach using concrete objects and movement activities

Differentiation and Support

For Learners Who Need More Support

• Use only two number cards at a time: 1 and 2.
• Use large objects that are easy to see and touch.
• Guide the learner’s hand while counting or writing, if appropriate.
• Repeat the phrase “one means just one” throughout the lesson.
• Allow the learner to answer by pointing, speaking, drawing, or showing one finger.

For Learners Ready for More Challenge

• Compare one with zero, two, and three.
• Ask the learner to find one object in each room of the home.
• Have the learner create and solve simple “one” story problems, such as “I had one apple and ate it. How many apples are left?”
• Invite the learner to write a short sentence containing the word “one.”

Conclusion: Recap and Reflection

Ask the learner to complete these statements:

• “The number that means one object is ______.”
• “One means ______ object.”
• “One thing I found today was ______.”

Hold up one object and ask the learner to explain what it represents. Then say:

“Today we learned that the numeral 1 represents one single object. We practiced finding one, counting one, moving one time, drawing one, and writing 1.”

Optional Follow-Up Practice

During the day, ask the learner to notice groups of one in real life. At bedtime, invite them to name three things they saw that came in a group of one.
