Lesson Script: Addition Using Concrete Materials to Make 10
Objective
Students will understand and apply the concept of addition through the use of concrete materials, enabling them to combine quantities to make a total of 10.
Duration
30 Minutes
Materials Needed
- Ten blocks or counters (e.g., Unifix cubes, counting bears, or similar)
- Whiteboard and markers
- Worksheets with addition problems
- Number cards (1-10)
- Small containers or bags for grouping materials
Lesson Outline
Introduction (5 minutes)
-
Greeting & Setting the Scene
Welcome the students and explain that today we will explore how to add numbers using physical objects.
-
Explain the Concept of Addition
Introduce addition as putting together two or more quantities to find a total. Use a simple description: “When we have some apples and we get more apples, we want to know how many apples we have altogether.”
Direct Instruction (10 minutes)
-
Demonstration with Concrete Materials
- Gather students around the workspace.
- Show the blocks or counters to the students. Place a group of blocks on the table.
- Start by placing 4 blocks in a container. Ask the students how many blocks are there.
- Next, add 6 more blocks to the initial 4 blocks.
-
Visual Representation
- Write the addition sentence on the whiteboard: 4 + 6 = 10.
- Explain that we started with 4 and added 6 more to make a total of 10.
- Emphasise that the blocks helped us see how the two groups come together to make one whole group.
-
Hands-On Practice
- Distribute 10 blocks to each student or pair.
- Instruct them to make different combinations that add up to 10 (e.g., 5 + 5, 3 + 7).
- Encourage them to represent this on the whiteboard as well.
Guided Practice (10 minutes)
-
Group Work
- In small groups, ask students to find all the possible ways to add blocks that make 10. Each group writes down their combinations on paper.
- Circulate among the groups to provide assistance and observe their understanding.
-
Share Discoveries
- After 5 minutes, bring the class back together.
- Ask each group to share one way they combined their blocks to make 10.
- Write these combinations on the whiteboard for visual reinforcement.
Independent Practice (5 minutes)
-
Worksheets
- Hand out a worksheet that requires students to fill in missing parts of addition sentences (e.g., 2 + __ = 10).
- Encourage them to use their blocks if they need to count for support.
-
Encourage Self-Checking
- Remind students to check their answers with their blocks as a way to verify their calculations.
Closure (5 minutes)
-
Reflect on the Lesson
- Gather students' attention to summarise what they've learned today about addition.
- Discuss how adding tiles or blocks made it easier to find totals.
-
Preview Next Steps
- Explain that in the next lesson, we will take these skills and apply them to number lines and other tools, bridging the use of concrete materials to abstract numbers.
-
Final Questions
- Open the floor for any last questions and thank students for their participation.
Assessment
- Observe student participation during group activities and discussions.
- Review completed worksheets for understanding of addition concepts and accuracy.
Additional Notes
- Provide additional support for students who may struggle by offering them extra time and one-on-one assistance.
- Consider adapting materials or methods for students with diverse learning needs.
By ensuring an engaging, interactive, and hands-on approach, students will better grasp the concept of addition as they work towards the goal of making 10 using concrete materials.
