Use inference and problem-solving skills to decipher the puzzles and uncover the hidden code.
Do You Have Your Library Card?
It’s Mateo’s first day at a brand new school and he’s already lost his library card.
Lucky for Mateo, the school librarian has crafted a clever way he can recover his card number and borrow his books.
Help Mateo Find His by Solving the Clues
Divide students into pairs or teams and provide each with a Study Book. Each book contains four challenges that reveal a shape and a number that students will use in the final maze to retrieve Mateo’s student number.
Interactive Final Clue
This resource also includes an interactive PowerPoint that is intended to be used as the final part of the mystery.
- Display the PowerPoint on a screen in the classroom/library as the students are completing the clues.
- Once students have completed all four clues and think they have Mateo’s correct student number, they can attempt to enter it into the keypad to see if it is a success.
- The PowerPoint easily resets to allow multiple students to take turns seeing if their code is correct.
Scaffolding + Extension Tips
We’ve designed this activity with differentiated versions of the Study Books to accommodate individual students’ abilities. Shapes on the front cover identify the three versions as follows:
- circle version—literal comprehension
- triangle version—inferential comprehension, halving single-digit numbers
- hexagon version—inferential comprehension, basic maths operations.
Note: all versions of the Book Shelves activity require students to sort books into fiction and non-fiction based on their titles.
