The "Save Sammy!" challenge sounds like a fantastic hands-on activity for your 5th graders. It's a great way to develop problem-solving, teamwork, and critical thinking skills. Students must work together to "save" Sammy, who has fallen out of his boat and needs to get his life jacket on before getting back into the boat. The twist? They can only use paper clips to move Sammy, the boat, and the life jacket—no hands!
