It’s important to note that you don’t HAVE to do presentations in school if you have a stutter. Communicate with your teachers and/or the disability office early on. Since it’s a bit late for this approach, I would just let your teacher and partners know the situation. Practice your three slides until you have them memorized. Slowwwww your speech down and relax I have to give work presentations now and I just talk as slow as possible. It keeps me from rushing and doesn’t make it as apparent should I have a block.
