Embedded Core Skills:

• Communication and Collaboration
• Critical Thinking and Problem Solving
• Creativity and Imagination

Learning Materials:

• Reference book: Lagos State Scheme of Work
• Picture charts showing objects of different lengths

Instructional Materials:

• Whiteboard
• Marker
• Visual aids of different lengths

Content: Today, we will learn about length and how to compare it. We will identify objects as short or long/tall and measure them using non-standard units like our index fingers or hand spans.
