Frankie Sparks and the Big Sled Challenge (Frankie Sparks, Third-grade Inventor)

Frankie Sparks uses her inventing skills to build the best sled ever in this third chapter book in the STEM inspired Frankie Sparks, Third-Grade Inventor series.

Frankie Sparks can't wait to enter the town-wide sled design contest. With the help of a team, she must design and build a sled using only cardboard and duct tape. And there are PRIZES!

Each team in the contest will be judged on:
1. Best looking sled.
2. Fastest sled.
3. Most team spirit.

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?
