Lesson Keywords

• Gadget – a small, special tool or device.
• Camera – a device that takes pictures or videos.
• Doorbell – a button that makes a sound when pressed, usually at a door.

Differentiation

• Extension: For pupils who grasp the concept quickly, the teacher can ask them to identify other security features they see around the school or their community (e.g., a fence, a gate, a lock on a door). They could also draw a picture of their favourite security gadget.

Note for teachers using this lesson plan

Prepare the instructional materials, especially the real or toy doorbell and security camera, before the lesson. These concrete objects are crucial for Pre-School Level 4 pupils to understand abstract concepts like “gadget” and “security.” Emphasize that these gadgets are there to help keep them safe, not to scare them. Encourage pupils to share examples from their own homes, but ensure the discussion remains positive and focused on safety. Observe if pupils can point to the gadgets and explain their basic function in their own simple words. Repetition of the rhyme and key terms will aid retention. For safety, always supervise when handling any real objects.
