Some words sound very much the same, but have different spellings. We call these words homophones. An example of this would be their and there. Though most speakers pronounce these words exactly the same way, these two words have completely different meanings. Their shows possession or ownership. There shows location. Knowing the difference between their and there isn't really that important when you are speaking, but it is very important when you are writing. Things can get pretty confusing for readers when a writer chooses the wrong the word from a set of homophones.
Common Core State Standards specify that students have to master word choice. That means that a student must be able to recognize when the word steal should be used instead of the word steel, and literally hundreds of more pairs like steal and steel. So how can students get prepared for this? The same way that one gets to Carnegie Hall: practice, practice, practice! To help with this, I've created a bunch of resources on homophones and word choice and posted them below.
These terms can be quite confusing, but if you know the meanings of the word roots, it is actually quite easy to remember.
