Here is a little maths problem for you!
Add these together:
1. The number of children in your class
2. The number of children sitting at the Brave lions table
3. The number of days you go to school each week.
Then add these together:
1. The number on our classroom door
2. The number on Mr. O Reilly's door
3. The number on Ms. Shanahan's door
Then take the first answer away from the second answer. Write it on a piece of paper and bring it to me in the morning to claim your prize!
