Detective Agency

Materials to prepare

• Connect your computer to the classroom screen and speakers. Check sound before children arrive. Internet is needed.
• Preview the activity and writing sheets. Print enough for your group, prepare word cards and an exit check, and keep the teacher guide nearby. Cut cards and print the matching spaces at the same scale.
• Prepare six paper letters f, l, a, n, i, p and the fan/lip pictures. Cut cards before class. No magnifier or working fan is needed; seated gestures are enough.
• Keep the lesson slides ready if a video does not play. Read the English notes and model the action yourself.
