Addition with 10 Frames

Overview

Grade Level: Kindergarten - Grade 2

Subject: Math

Duration: 20 minutes

Curriculum Link: Common Core State Standards for Mathematics (CCSSM)

• Kindergarten: K.OA.A.1 — Represent addition with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
• Grade 1: 1.OA.A.1 — Use addition within 20 to solve word problems involving situations of adding to, putting together, and comparing.
• Grade 2: 2.OA.B.2 — Fluently add within 20 using mental strategies.

Objective

Students will develop an understanding of addition up to 20 using 10 frames, enhancing their computational skills and visualizing mathematical concepts.

Materials

• 10 Frames (laminated or on paper)
• Counters or small objects (e.g., buttons, coins)
• Whiteboard and markers
• Visual aids illustrating real-life scenarios for addition
• Number cards (1-10)

Lesson Activities

1. Introduction (3 minutes)

• Objective: Engage students by relating addition to real life.
• Activity: Begin with a simple story about sharing candies. Draw two baskets on the board and ask students how many candies in both baskets if one has 5 and the other has 3.

2. Demonstration (4 minutes)

• Objective: Visualize addition using 10 frames.
• Activity:
  • Display a 10 frame using a large visual aid.
  • Place 5 counters on the 10 frame. Ask students how many more are needed to make 10.
  • Gradually add more counters and ask students for the new total each time.
  • Highlight that 10 frames can help visualize addition as a sum of parts.

3. Guided Practice (6 minutes)

• Objective: Practice addition within 20 using hands-on activities.
• Activity:
  • Group Task: Divide students into pairs. Give each pair a 10 frame and a set of counters.
  • Scenario: Present scenarios, e.g., "You have 6 apples and find 4 more. How many apples do you have now?"
  • Pairs place 6 counters, then add 4 more and count the total.
  • Encourage students to switch roles between placing counters and counting to engage both partners.

4. Independent Practice (4 minutes)

• Objective: Allow students to explore on their own.
• Activity:
  • Distribute number cards.
  • Have each student pick two cards and use the 10 frame to add the numbers.
  • Encourage students to share their results with a partner and discuss their strategies.

5. Conclusion (3 minutes)

• Objective: Reinforce the day's concepts.
• Activity:
  • Bring the class together and review the key concept of using 10 frames.
  • Ask a few students to share what they learned.
  • Pose a final problem: "If we start with 9 and add 6, how might we break this into parts to use our 10 frame tool?" Encourage creative thinking and allow students to discover: “9 + 1 and then +5”.

Assessment

• Observe student participation during pair activities.
• Assess understanding through the independent practice.
• Provide feedback and correct misconceptions during class discussions.

Differentiation

• Support: Offer additional guidance by modeling each step for students who need more help.
• Challenge: For advanced students, introduce subtraction using the 10 frame or expand problems beyond direct addition (e.g., simple word problems).

Reflection

• Post-lesson, reflect on which students grasped the concept and who may need targeted support in the next session.
• Consider alternative methods or tools to enhance understanding if necessary.
