class 8 NCERT bridge course Answers Activity W2.2: A Mathematical Tambola

 Activity W2.2: A Mathematical Tambola

Each student gets a tambola ticket with 15 numbers randomly selected from 1 to 90. 

 Instead of directly calling out numbers, the host will give a math-based clue for each number. 

For example, instead of saying 2, it may be said ‘An even prime number’. 

 Players are required to solve the clue to mark the correct number on their ticket. 

 Winning rules: 

1. Early five: first to mark any 5 numbers. 

2. Top row/middle row/bottom row: First to mark all numbers in a row. 

3. Full house: first to mark all 15 numbers. 

4. Students will mark question numbers on each strike out for later verification
