  • Crayon or washable marker
  • Number cards, including the number 1
  • Small objects such as blocks, buttons, toy animals, or snacks
  • One paper plate or small bowl
  • Play dough or clay
  • Optional: music for a movement game

Learning Objectives

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

  • Recognize the number 1.
  • Say the number 1.
  • Show one object when asked.
  • Trace or make the shape of the number 1.
  • Connect the number 1 with the idea of “one thing.”

Success Criteria

I can:

  • Point to the number 1.
  • Count one object.
  • Make a number 1.
  • Tell about one thing I have or see.

Introduction: “One Special Thing”

Hook: Hold up one favorite toy or object.

Say: “Look! I have one toy. One means just one thing. Can you show me one finger?”

Invite the child to show one finger and say, “One!”

Tell the child: “Today we will learn about the number 1. We will find one thing, move one time, and make the number 1.”

Body of the Lesson

1. I Do: Meet the Number 1

Show a large number 1 card.

Say:

  • “This is the number 1.”
  • “We say one.”
  • “The number 1 tells us there is one thing.”

Place one block beside the number 1. Touch the block and count slowly: “One.”

Show a group of two or three objects and say, “This is more than one. Let’s find the group with just one.”

Quick check: Hold up the number 1 and another number card. Ask, “Which card says one?”

2. We Do: Find One

Place several objects in front of the child.

Say: “Let’s take one object. You choose which one.”

Take turns:

  1. Ask the child to choose one object.
  2. Place it on the paper plate or in the bowl.
  3. Touch it and count, “One.”
  4. Return it and repeat with a different object.

Try playful examples:

  • “Can you find one red block?”
  • “Can you bring me one stuffed animal?”
  • “Can you put one button in the bowl?”

Think and talk: Ask, “What is one thing you can see in this room?” Accept answers such as “one chair,” “one lamp,” or “one window.”

3. We Do: Move One Time

Say: “We are going to move one time. Watch me.”

Choose one movement, such as one jump. Say, “One jump!” and jump once.

Invite the child to copy you. Try several actions:

  • One clap
  • One stomp
  • One twirl
  • One wave
  • One silly face

After each movement, ask, “How many did we do?” Help the child answer, “One!”

4. I Do: Make the Number 1

Draw a large number 1 slowly.

Say: “Start at the top. Go down. This makes number 1.”

Trace the number with your finger while saying, “Down for one.”

Make the number 1 in the air with your finger. Invite the child to copy you.

5. You Do: Number 1 Art

Give the child paper and a crayon or marker.

Offer these choices:

  • Trace a large number 1.
  • Draw a large number 1 independently.
  • Make the number 1 with play dough.
  • Decorate one large number 1 with stickers or dots.

As the child works, use simple prompts:

  • “Where do you start?”
  • “Which way does your finger go?”
  • “What number are you making?”

6. Real-World Number 1 Hunt

Say: “Let’s look for the number 1 in our home.”

Search together for the number 1 on a clock, book, calendar, toy, package, or keyboard. Each time the child sees it, say, “You found number 1!”

If the number 1 is not easy to find, make your own number 1 cards and place them around the room.

Formative Assessment

During the lesson, check understanding by asking the child to:

  • Point to the number 1 among two or three cards.
  • Give you one object.
  • Show one finger.
  • Do one clap or one jump.
  • Say the number shown.

Give specific feedback:

  • “You gave me one block. You counted carefully.”
  • “You found the number 1.”
  • “You started at the top and went down.”

Summative Assessment: “Show Me One” Game

Place several objects and number cards nearby. Ask the child to complete these challenges:

  1. “Show me the number 1.”
  2. “Give me one object.”
  3. “Show me one finger.”
  4. “Make one clap.”
  5. “Draw or build a number 1.”

The child is successful when they complete at least four of the five challenges with little or no help.

Differentiation and Support

  • For extra support: Use only two choices at a time. Physically guide the child’s finger while counting one object.
  • For visual learners: Use bright number cards and place one object directly beside the number 1.
  • For active learners: Practice one-step movements such as one jump or one stomp.
  • For children ready for more: Compare one with zero and two. Ask, “Which group has one? Which group has more?”
  • For digital learning: Display a large number 1 on a screen and let the child find one object nearby.

Conclusion and Recap

Hold up the number 1 and ask:

  • “What number is this?”
  • “How many things does one mean?”
  • “Can you show me one finger?”

Say: “Today we learned that the number 1 means one thing. We found one object, moved one time, and made the number 1.”

Finish with a short celebration: clap once together and say, “One is fun!”

Optional Follow-Up Activities

  • Put one toy in each room and go on a “one toy” hunt.
  • Read a counting book and look for groups with one object.
  • At snack time, count out one cracker, one fruit piece, or one spoon.
  • Sing a simple song about one little finger or one little duck.
