Morning Message for April 3

Good Morning Mathematicians! Are you ready to receive your first springtime stumper? I’ve been waiting two weeks to bring this one to you!

Love, Mrs. Gibbs-Wilborn

On the first day of spring, I went outside and gathered some objects for my nature box. I found one rock, a tree branch, a leaf and a log. Can you guess which object might have been:

The longest?

The heaviest?

The roundest?

The lightest weight?

What made you think this?
