Gerrymandering is a unique topic for history teachers to teach and can bee difficult for some students to grasp. It is mixed in with the electoral collage and looking at how votes are counted inside of a district. One of the best tools I've found to teach this concept to my students was not even an educational tool it was a game on the google play store! The app is called Gerrymander: Rig The Election. It's bright and colorful with a built in tutorial that teaches the basics and introduces students to the idea of drawing district lines.
I introduced this to students by simply showing them the app first and giving them 10 minutes to play. After that we grouped back up and had a conversation about what they saw as the objective in the game and discussed whether we thought it was fair or not. This was my first time teaching the concept but I thought it went really well overall. I was very happy with how engaged the students were. I was worried concerning the topic would be dry and unappealing but this was a way that really worked well for them.
