Price Tag Creation

Overview

In this 30-minute interactive lesson, 1st grade students will engage in a hands-on activity to create price tags for items in a mini market setting. By practicing simple addition and number writing, students will connect numerical values with real-world objects, developing early math skills aligned with the Common Core State Standards.

Standards Alignment

Common Core State Standards (CCSS) – Mathematics

• 1.OA.A.1: Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions.
• 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.
• 1.NBT.C.4: Understand that the two digits of a two-digit number represent amounts of tens and ones.

---

Learning Objectives

By the end of this lesson, students will:

• Write numbers up to 20 clearly on price tags.
• Solve simple addition problems related to item prices (e.g., 3 + 2 = 5).
• Associate numerical prices with physical objects in the mini market.
• Demonstrate understanding of value and number representation.

---

Materials Needed

• Mini market objects (toy fruits, snacks, household items, etc.)
• Blank price tags or cardstock pieces (1 per student or per item)
• Pencils, crayons, or markers
• Addition problem cards with simple sums up to 20
• Whiteboard or large chart paper
• Number line (1-20) displayed visibly in the classroom

Lesson Timeline

1. Opening (5 minutes)

• Engage: Gather students in a circle; briefly revisit last lesson’s concept of items in the mini market.
• Objective Sharing: Introduce today’s goal: "Today, we’re going to make price tags by solving addition problems and writing numbers!"
• Quick Counting Warm-up: Count aloud together from any number up to 20 to get comfortable with numbers.

2. Guided Instruction (8 minutes)

• Demonstration: Teacher shows a mini market item (e.g., toy apple) and an addition problem card, e.g., 4 + 3.
• Think Aloud: Solve the problem on the whiteboard; write the answer “7” and discuss what it means as a price.
• Model Writing: Show how to neatly write “7” on a price tag and attach it to the item.
• Class Practice: Repeat with 2-3 more examples, asking students to suggest solutions and numbers aloud.

3. Collaborative Activity (12 minutes)

• Task: Students work in pairs or small groups with a set of mini market items and addition cards.
• Instructions:
  • Solve the addition problem on the card.
  • Write the sum clearly on a price tag.
  • Attach the price tag to the correct item.
• Teacher Role: Circulate, prompt with questions (“How did you find the answer?”, “Can you show me the number on the number line?”), and support where needed.

4. Sharing and Reflection (4 minutes)

• Invite a few groups to present one item and their price tag, explaining how they figured out the price.
• Reinforce correct addition strategies and number formation.
• Ask students how they think prices help when buying things (linking math to real life).

5. Closing and Assessment (1 minute)

• Quick thumbs-up/thumbs-down: “Do you feel confident writing numbers for prices and adding numbers?”
• Collect price tags for informal assessment or have students place price tags on a display “mini market” corner to revisit during the unit.

Differentiation Strategies

• For students needing extra support: Provide number lines or counting manipulatives (like counters) to physically model addition.
• For advanced students: Include addition problems with sums up to 30 or introduce simple story problems related to the mini market.

Teacher Notes

• Encourage neat handwriting to support foundational numeracy skills.
• Connect math language to everyday shopping vocabulary (price, cost, add, total).
• Use positive reinforcement and celebrate all attempts to build confidence.
• Consider photographing the mini market with labeled prices as a visual reminder for students.

---

Assessment

• Informal observation during paired work and discussions.
• Check accuracy and legibility of written sums on price tags.
• Evaluate students’ ability to explain their addition process during sharing.

By integrating hands-on practice with addition and number writing, this lesson creates an immersive, meaningful experience in math that young learners will enjoy and remember. The direct connection between numbers and their use in the mini market empowers students to see math as part of their daily world.
