Counting Fun Together

Overview

This is the first lesson in the 12-lesson unit "Math Adventures in First Grade." The focus is on introducing counting aloud and recognizing numbers from 1 to 20 using hands-on, cooperative learning. Activities are designed to engage young learners in collaborative ways using Kagan strategies, with scaffolding to meet diverse learning needs in a behavior K-2 classroom.

Standards Alignment

Common Core State Standards (CCSS) - Mathematics:

• CCSS.MATH.CONTENT.K.CC.A.1
  Count to 100 by ones and by tens.
  (This lesson begins foundational counting skills toward this standard.)

• CCSS.MATH.CONTENT.K.CC.B.4
  Understand the relationship between numbers and quantities; connect counting to cardinality.

• CCSS.MATH.CONTENT.K.CC.B.5
  Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle.

Learning Objectives

By the end of this lesson, students will be able to:

• I can count aloud from 1 to 20 with my friends.
• I can recognize and show numbers 1 to 20 using objects and number cards.
• I can work together as a team to count objects in groups.

---

Success Criteria

• Students accurately count aloud in groups using a variety of objects.
• Students can match counted objects to the correct number card from 1 to 20.
• Students demonstrate cooperation and take turns during Kagan cooperative learning activities.

---

Materials

• Number cards 1–20 (large and colorful)
• Small objects for counting (e.g., blocks, counting bears, buttons)
• Large floor number mat (1 to 20 arranged visually)
• Whiteboard and markers
• Counting buckets or plates
• Visual aids with numbers and dots representations (dyslexia-friendly fonts such as OpenDyslexic)
• Timer or stopwatch (for timed activities)

---

Lesson Breakdown (60 minutes)

1. Warm-Up (5 minutes) — Counting Song & Body Movement

• Sing a counting song together (e.g., “1-20 Counting Chant”) with hand claps or stomps to engage multiple senses.
• Encourage students to count aloud and move their hands/body to different numbers (clap once for 1, twice for 2, etc.).

Purpose: Activates prior knowledge and warms students up to verbal counting.

---

2. Mini-lesson (10 minutes) — Hands-On Number Exploration

• Show number cards 1–20 one at a time; ask students to “read” the number aloud.
• Demonstrate counting with objects by placing the exact number of items on a plate or bucket matching the card.
• Use the floor number mat for students to place objects on corresponding numbers.

Teacher Scaffold: Use visual cue cards with dots/numbers in dyslexia-friendly font. Repeat and model wording.

---

3. Kagan Team Activity: “Number Line-Up” (20 minutes)

• Divide students into pairs or groups of 4 (4 groups for 8 students).
• Each group receives a mixed set of number cards and counting objects.
• Using “Round Robin” strategy, one student pulls a number card, the partner counts out the matching number of objects, then they switch roles.
• After several rounds, groups combine to place all number cards and object groups on the floor number mat in order from 1 to 20, assisting each other.
• Encourage “Showdown” where one student shows a card and the group counts aloud together to confirm correctness.

Differentiation:

• For students who need extra support, provide pre-counted sets or limit numbers to 1–10.
• For advanced learners, challenge grouping objects into tens and ones (e.g., 14 as 10 + 4 objects).

4. Center Rotation: Counting Stations (20 minutes)

Set up 2–3 hands-on centers. Each center allows for scaffolded counting practice:

• Center 1 - Object Counting: Students count and place objects on plates to match numbers shown on cards.
• Center 2 - Number Match: Students match physical number cards with drawn dots on a board or worksheet in dyslexia-friendly print.
• Center 3 - Movement Counting Game: Students hop, jump, or clap the number of times shown on a card (physical engagement is great for behavior management).

Students spend about 6-7 minutes per center with teacher or aide support.

---

5. Closing & Assessment (5 minutes)

• Gather students in a circle. Use a “Flash Count” quick activity: flash number cards from 1 to 20 randomly, students shout out the number and show fingers to match.
• Use thumbs-up or nodding to check student confidence.
• Ask students to share one thing they learned or liked (“I can count to 20” or “I liked counting blocks with my friends”).

---

Differentiation Strategies

• Use paired peer support with buddy reading and counting for students needing extra guidance.
• Visual supports and manipulatives to connect numbers with quantities.
• Step-by-step modeling and check-ins for students with attention challenges.
• Reduced number range (1–10) for beginning counters.
• Use dyslexia-friendly fonts, high contrast colors, and uncluttered visuals.
• Small group instruction for students struggling with counting/routines.

---

Extension Activities (Advanced Learners)

• Count backwards from 20 to 1 together.
• Practice simple addition using counted objects (e.g., 7 + 5 objects).
• Introduce skip counting by twos using groups of objects or fingers.
• Create their own “number stories” to explain groups counted.

---

Reflection Notes for Teacher

• Monitor engagement and interaction in teams; adjust groups as needed to support behavior and learning levels.
• Reinforce positive teamwork and celebrate counting milestones.
• Use formative assessment during centers to plan next lesson focusing on number relationships and place value concepts.

This lesson offers a rich combination of multisensory, cooperative learning and scaffolding to ensure all students, including those with behavioral and learning challenges, access foundational counting skills aligned with Common Core standards. It promotes a joyful math environment filled with collaboration and movement—perfect for young learners’ development!
