My First 3-Act Task

I've loved going into classrooms and modeling 3-act tasks. Graham Fletcher has some amazing 3-act tasks on his website. https://gfletchy.com/3-act-lessons/

But I felt like it was time to try my hand at it and make a few of my own.  Since Valentine's Day is coming up soon, I decided that this was the perfect theme for the 3-act tasks I would create.

Disclaimer: Please be kind- these as my first attempts...
