Give the kids each a pen, some floral green tape and a silk flower.  They can make pens for their moms that will have a flower on top.  That way no one will take their mom's pen away from her desk!!!  You cut the silk flower off leaving a stem that is a couple inches long, then you hold the silk flower so that it sticks out and becomes the top of the pen and then you wrap it with green floral tape.
 

Attach the following poem:

My Mom’s Pen

This pen has a flower
For everyone to see
So don’t take it!
Don’t move it!
It’s mom’s, to her from me!
Mom will always find her pen now
Because it’s plain to see
Mom’s pen has flower
And I put it there from me!
