Hook: The Case of the Missing Treasure Map

Scenario Set-Up:

As the students enter the classroom, they notice something intriguing on their desks – a sealed envelope marked ‘TOP SECRET’. The envelope contains a message from a fictional character, Detective Algebra, who needs their help to solve a mathematical mystery!

Dear Brilliant Mathematicians,

I, Detective Algebra, need your keen minds to help me recover a missing treasure map! The only clue I have is a code that involves expansion and factorisation. Without the map, I cannot locate the treasure of knowledge hidden in the Castle of Mathoria!

Your mission, should you choose to accept it, is to decode the clues I’ve left behind. Are you ready to crack the case?

Sincerely,
Detective Algebra

Activity: Decoding Clues

Instructions:

1. Group Formation:

   • Divide students into small groups of 4-5. This encourages collaboration and discussion.

2. Distributing the Clue Sheets:

   • Each group receives a clue sheet that presents problems requiring expansion and factorisation. For instance:
     • Clue 1: Expand the expression ( (x + 3)(x - 2) ).
     • Clue 2: Factor the expression ( x^2 - x - 6 ).

3. Decoding Process:

   • After solving the problems, groups must write down the answers in the order they were presented.
   • Each answer corresponds to a letter (A=1, B=2, C=3, etc.) to form words related to mathematics or the treasure itself.

4. Discussion:

   • Once decoded, each group presents their findings and discusses the importance of both expansion and factorisation in solving real-world problems and how these concepts are connected to various mathematical ideas.

Transition to Lesson

Conclude the activity by highlighting how expansion and factorisation are powerful tools not just for solving puzzles, but also for tackling complex mathematical problems in algebra. Today, we will explore these concepts in depth and equip ourselves with the skills needed to help Detective Algebra find the treasure!
