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? | Frankie Sparks and the Big Sled Challenge by Megan Frazer Blakemore, Hardcover | Indigo Chapters
