Frankie Sparks uses her inventing skills to trap a leprechaun in this fourth chapter book in the STEM inspired Frankie Sparks, Third-Grade Inventor series.

It’s springtime in Ms. Cupid’s class, and the entire class is excited to build their very own leprechaun traps. Maybe, if they catch one, they will all get the gift of good luck!

And after a few magical clues, it looks like there might be a leprechaun on the loose in Frankie Sparks’s house! Her best friend, Maya, is convinced the leprechaun exists, but Frankie has her doubts—especially when it feels like every trap she designs fails! Will Frankie and Maya find their lucky charm, or figure out how to create some luck all on their own?
