As a dungeon master, I run games for new players often enough that I went ahead and made a Dice Label Table. It can be overwhelming trying to remember all the different types of dice. I tried to make this as simple as I could. Print it out, cut it up, and then put out the dice. The shapes and labels will help players find the dice faster leading to less frustration on all sides. Let me know how it works for you!
Update: I made a rainbow version too!
