Frankie Sparks and the Big Sled Challenge (Frankie Sparks, Third-Grade Inventor, Bk. 3)

Frankie Sparks can't wait to enter the town-wide sled design contest! And there are prizes! But even though Frankie might know a lot about building a sled, it turns out she still has a lot to learn about building a team.

With lots of twists, turns, and big bumps along the way, can Frankie and her fellow super sled designers create a dream machine - and a dream team?
