Lesson Plan: Bead Combinations (Decomposing Numbers)
Subject: Mathematics
Grade Level: Reception / Kindergarten
Duration: 30 Minutes
Topic: Bead Combinations (Decomposing Numbers)
Objectives
By the end of this lesson, students will be able to:
- Understand the concept of decomposing numbers using bead combinations.
- Create different combinations of beads to represent the same number.
- Develop counting and addition skills through hands-on activities.
Materials Needed
- Beads in various colors (Red, Blue, Yellow, Green)
- String or pipe cleaners (to make bead combinations)
- Chart paper or whiteboard
- Markers
- Worksheet for homework
Introduction (5 Minutes)
-
Engage the students: Start by showing the students a group of beads. Ask:
- "What colors do you see?"
- "How many beads do we have?"
-
Explain the concept: Introduce the idea of combining numbers. For example, explain that 3 beads can be made up of 2 red and 1 blue bead, or 1 red and 2 blue beads.
Direct Instruction (10 Minutes)
-
Demonstrate: Use the chart paper to illustrate number combinations. Write out a number (e.g., 5) and have students help you break it down into different bead combinations:
- 5 = 1 + 4
- 5 = 2 + 3
- 5 = 0 + 5
-
Use beads: Invite students to come up and use the beads to show these combinations with the beads they have.
Guided Practice (10 Minutes)
- Team Activity: Divide students into small groups and give each group a set of beads.
- Task: Ask them to create all the different combinations for a number you choose (start with 4, then progress to 5). Encourage them to work together and take turns.
- Share: After 5-7 minutes, have each group share one of their combinations with the class.
Independent Practice (5 Minutes)
- Worksheet Distribution: Hand out a simple worksheet where students must draw beads or color combinations for the numbers 1, 2, 3, and 4. Provide space for them to write out different combinations next to each number.
Closing (5 Minutes)
- Review what they learned about decomposing numbers into bead combinations.
- Ask a few students to share what they created on their worksheets.
Homework
Complete the worksheet at home. Tasks include:
- Draw beads to represent each number (1 through 5).
- Write down combinations for each number.
Homework Worksheet Sample

1 =
- Combination: "1 blue"
- Drawing: [draw a single bead]
-
2 =
- Combination: "2 red"
- Drawing: [draw two beads]
-
3 =
- Combination: "1 red + 2 blue"
- Drawing: [draw three beads]
-
4 =
- Combination: "1 green + 3 yellow"
- Drawing: [draw four beads]
-
5 =
- Combination: "2 blue + 1 red + 2 green"
- Drawing: [draw five beads]
Answers for Homework
- 1: 1 blue
- 2: 2 red
- 3: 1 red + 2 blue
- 4: 1 green + 3 yellow
- 5: 2 blue + 1 red + 2 green
This lesson plan encourages hands-on learning through bead combinations while reinforcing counting and addition skills essential for kindergarten students.
