Counting with Fun

Objective

By the end of the lesson, students will be able to count, read, and write numbers 1 to 20, and understand the concept of quantity corresponding to these numbers, following Common Core State Standard CCSS.MATH.CONTENT.1.NBT.B.2: Understand that the two digits of a two-digit number represent amounts of tens and ones.

“I Can” Statements

• I can count numbers from 1 to 20.
• I can write numbers from 1 to 20 correctly.
• I can match numbers to quantities using objects.

Success Criteria

• Students accurately count aloud up to 20 without skipping.
• Students write numbers 1-20 legibly on their whiteboards or paper.
• Students correctly match number cards to sets of objects during an activity.

Materials

• Number cards 1-20
• Sets of 1-20 small objects (e.g., counters, beans, or blocks)
• Individual whiteboards and markers
• Counting song audio or video
• “Number Detective” hats (paper hats or headbands to motivate engagement)
• Visual number chart 1-20

Lesson Breakdown (35 min)

1. Warm-Up (5 minutes)

Activity: Counting Song & Movement

• Play a lively counting song from 1 to 20.
• Encourage students to sing along and use fingers to count.
• Incorporate movement: jump or clap on each number to engage motor skills.

Differentiation: For learners needing sensory input, allow tapping or drumming with hands instead of jumping.

---

2. Explicit Teaching (7 minutes)

Activity: Number Chart Exploration

• Display a large number chart 1-20.
• Point to each number as you count aloud together.
• Explicitly show the formation of numbers 1-20 writing on the board.
• Demonstrate recognizing quantities by grouping objects per number.

Differentiation: Use a pointer or scanner for visually tracking numbers; provide magnified number cards for those with visual impairments.

3. Guided Practice (10 minutes)

Activity: Number-Object Match Game - "Number Detectives"

• Distribute “Number Detective” hats to students.
• Divide students into pairs; give number cards 1-20 and corresponding sets of objects.
• Each pair practices matching the number card with the correct quantity of objects.
• Students take turns saying “I spy with my detective eyes…” and stating a number and quantity.
• Teacher circulates, offering positive feedback and guidance.

Differentiation:

• For advanced learners, encourage counting objects beyond 20 or simple addition of two sets.
• For emerging learners, reduce the number range to 1-10 and provide guided scaffolding.

---

4. Independent Practice (8 minutes)

Activity: Whiteboard Number Writing

• Each student uses a whiteboard to write numbers 1 to 20 as teacher dictates.
• Teacher calls out numbers randomly for students to write.
• After writing, students hold up boards for quick formative assessment.

Differentiation:

• Provide number tracing templates for students needing fine motor help.
• Challenge higher-level learners to write numbers in reverse order or write a simple number sentence (e.g., “10 is 5 and 5.”)

---

5. Closing & Assessment (5 minutes)

Activity: “Count & Tell” Circle

• In a circle, each student says a number between 1 and 20 and shares a fact about it (e.g., how many fingers it is, or something they like that number of).
• Teacher uses anecdotal notes to assess understanding and engagement.

---

Assessment

• Informal observation during activities for accurate counting and matching.
• Whiteboard writing for correct numeral formation.
• Participation and ability to express quantity-number relationships verbally.

---

Teacher Reflection & Notes

• Adjust pacing based on student engagement and understanding.
• Use positive reinforcement and praise during “Number Detective” activities.
• Consider recording the counting song for students to practice at home.

---

Additional Differentiation Strategies

• Use tactile number cards (sandpaper or textured) for sensory learners.
• Include peer buddy support for ELL or students needing language assistance.
• For students with high energy or attention needs, incorporate small body breaks by standing up and acting out numbers.

By following this lesson, 1st graders will build foundational number sense with multi-sensory engagement, aligned tightly with CCSS standards and employing differentiation to meet a variety of learning needs.
