I find that when it comes to writing my children mix up their homophones all the time. I have poster up o the walls, dictionaries available and of course specific homophone reviews and still they struggle. What I have done this year is create a mini homophone paper that students can keep with them. I tape them to each students desk (near their name tag), so that it is easily accessible when they are writing. My co-worker has them glued into each students work book. Either way, they have made a big difference in reducing homophone issues in our students writing. and now, I have made it available for you! Enjoy!
