students are in fourth grade?

you know your answer is correct.

Thanksgiving Math Challenge

Jack was scared as he knocked on the door. A low voice said,
"Before I open the door, you must say the secret number."

Here are some clues:

• It is less than 325.
• If you count by 5's, you say its name.

on a piece of paper and give it to Ms. Earl on Tuesday.
Happy Thanksgiving!
