You'll likely encounter different learning styles. Some people will do just fine with written or verbal instructions. Others will need to do the thing to understand. You might have to sit beside some people and talk them through the movements, or 'hand over hand' with them until they memorise the action of knitting. Some people will do better with big, chunky needles and yarn, others will do better with smaller. Some people will struggle to co ordinate movements that need both hands. Just try and see what people are struggling with and tailor your help accordingly. Some people actually learn better from videos that they can stop, start and rewind as needed. Knitting Help is great for this, it has great, free instructional videos that are good quality but not massive.

Also, even if you're learning, sometimes it's disheartening to just make things for practice. Choose a project like a garter stitch scarf, dishcloth, or potholder that is super basic but gives an actual, practical article at the end.
