Homonyms are words that sound the same but that have different meanings. There/their/they're and to/too/two are sets of homonyms that are commonly used (and confused) by students, but there are many others in the English language. The following resources provide a list of lesson plans teachers can use to introduce homonyms to students as part of the language arts curriculum.
Homonyms are generally introduced to students at the middle school level, although many students may be familiar with homonyms simply from everyday speech. While most people can easily identify common homonyms, there are some uncommon homonyms that are not recognized as frequently.
The following links contain lesson plans designed to help teach the concept of homonyms to students of various grade levels, or to give students additional practice with homonyms. Most of the resources are printable, although some of the links are links to online sources of homonym quizzes that can be used to create your own printable worksheets.
