Counting with Strokes

Overview

Grade: 1 & 2
Duration: 45 minutes
Class size: 18 students
Unit: Understanding Numbers to 100
Lesson 1 of 4: Introduction to Numbers
Common Core Alignment:

• CCSS.MATH.CONTENT.1.NBT.A.1: Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
• CCSS.MATH.CONTENT.2.NBT.A.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones. (Begin with smaller numbers like up to 20 for foundation)
• CCSS.MATH.PRACTICE.MP2: Reason abstractly and quantitatively
• CCSS.MATH.PRACTICE.MP7: Look for and make use of structure

Learning Objectives

By the end of this lesson, students will:

• Represent numbers up to 20 by drawing strokes and grouping them into bundles of 5
• Count aloud confidently to 20 and show understanding of quantity through visual representation
• Understand the idea of “groups” or “bundles” as a precursor to place value foundations
• Develop fine motor skills by drawing and grouping strokes

---

Materials

• Whiteboard and markers
• Student individual whiteboards or drawing paper
• Pencils or crayons
• Bundled sticks/manipulatives (e.g., popsicle sticks or pipe cleaners bundled into 5s)
• Number cards (1-20)
• Chart paper: pre-drawn number bundle example (five groups of five strokes each for the number 25 as a reference)

Lesson Timeline

Time	Activity	Details
0-5 min	Warm-up Counting Game	Engage students in a “Counting Around the Circle” activity: Each child says the next number from 1 to 20, encouraging fluency and group participation.
5-10 min	Introduce Strokes and Bundles Concept	On the whiteboard, demonstrate drawing strokes (
10-20 min	Guided Practice with Drawing	Each student draws the number 7 (for example) using strokes, then groups them into one bundle of 5 and 2 single strokes. Teacher circulates to provide help and encourage discussions about grouping. Repeat for a few other numbers: 11, 13, 18, emphasizing bundles of five and extra strokes.
20-30 min	Manipulative Activity - Bundle Building	Give each student a set of sticks or pipe cleaners. Call out numbers between 1 and 20, allowing students to build bundles of five sticks plus any extras. Pair students for peer-checking, sharing how they grouped their sticks. Discuss how this relates to what they drew.
30-40 min	Number Representation Matching Game	Display number cards (1-20). Students match their drawings or bundle builds to these cards. Each chooses a card, then either draws or uses sticks to represent that number accurately. Share with a peer or in small groups to explain how they represented their number.
40-45 min	Review & Exit Ticket	Ask each student to draw the number 14 using strokes and bundles on their whiteboard. Collect their work as an exit ticket to assess understanding. Use this time for quick individual checks. End with a recap emphasizing the usefulness of bundles for easy counting and preparation for place value concepts.

Differentiation & Support

• For students who excel: Challenge them to create numbers beyond 20 using multiple bundles.
• For students needing extra help: Use larger bundles (groups of 2 or 3) for initial counting before moving to 5s. Pair with attentive peers.
• Use tactile manipulatives for kinesthetic learners.

---

Assessment & Reflection

• Informal assessment through observation during activities, listening for correct counting and grouping.
• Exit ticket drawing (number 14) to check ability to represent numbers with strokes and bundles.
• Teacher notes on student verbal explanations and peer discussions to evaluate conceptual understanding.

---

Extension Ideas

• Connect bundles to tally marks for future lessons.
• Use simple stories or counting rhymes to incorporate bundle counting in everyday contexts.
• Digitally explore interactive apps or tools that simulate bundling strokes for at-home reinforcement.

---

Teacher Tips

• Encourage students to verbalize their thinking aloud as they group strokes. E.g., "I made one group of five sticks and two more sticks, so that's 7."
• Celebrate mistakes as learning moments to deepen conceptual understanding.
• Keep manipulatives accessible after the lesson for continuous exploration.

This lesson balances concrete and visual learning, setting strong foundations aligned with Common Core standards for place value and number sense, engaging young learners through multimodal representation and active participation.
