Making Sets of 3

Introduction

Objective:

Students will understand the concept of grouping objects into sets of three, improving their counting skills and understanding of basic number concepts.

CA Education Standards:

• Mathematics: K.CC.4 - Understand the relationship between numbers and quantities; connect counting to cardinality.
• Mathematics: K.MD.3 - Classify objects and count the number of objects in each category.

Materials:

• Counting blocks (at least 72 for individual work)
• Picture cards with images of objects (e.g., animals, fruits, toys) in various quantities
• Small bins or containers to hold sets
• Whiteboard and markers
• Crayons and paper

Lesson Outline

1. Warm-Up (5 minutes)

Activity:

• Greeting and Group Counting: Start the lesson with a greeting song. Then gather students in a circle on the carpet.
• Choral Counting: Together, count out loud from 1 to 10 using your fingers to show each number.
• Introduce Sets of 3: Explain that today’s activity will be about grouping objects into sets of three. Show an example using the counting blocks.

2. Direct Instruction (5 minutes)

Activity:

• Demonstration: On the whiteboard, draw three apples. Count them out loud: "One, two, three apples. This is a set of three."
• Visual and Verbal Cues: Show picture cards with objects grouped in threes. For each card, count the items together with the students.
• Engaging Question: Ask, "How many items do we need to make another set of three?" Encourage responses and affirm correct answers.

3. Guided Practice (5 minutes)

Activity:

• Individual Hands-On Practice: Give each student a small bin of counting blocks.
• Instructions: Ask students to create as many sets of three as they can using their blocks. Move around the classroom, assisting students who need help.
• Count Together: Once a few sets are made, pause and have students count with you: "One, two, three blocks. One set of three!"

4. Independent Practice (5 minutes)

Activity:

• Picture Sorting: Distribute picture cards among students.
• Pair Work: In pairs, students sort cards into sets of three images. Each pair uses a bin to hold their sets.
• Share with Class: Ask a few pairs to share their sets of three with the class, explaining what they grouped and counted.

5. Conclusion (3 minutes)

Activity:

• Reflective Discussion: Gather students back in a circle on the carpet. Discuss what they learned about making sets of three.
• Question & Answer: Ask, "Can someone tell me what a set of three is?" Encourage responses and validate learning.
• Praise & Positive Reinforcement: Celebrate students’ efforts with praise and maybe a fun sticker.

6. Cool Down (2 minutes)

Activity:

• Colouring Activity: Provide each student with a colouring sheet containing groups of different objects. Ask them to colour sets of three objects using their favourite colour.
• Wrap-Up Song: End the session with a short and fun song related to counting or numbers.

Additional Notes

• Classroom Management: Ensure students are engaged by varying the tone of your voice and maintaining a lively pace.
• Differentiation: Provide additional support to students who struggle with counting by offering one-on-one help or allowing them to work with a peer.
