Consider which educational philosophy you want to teach your child or class. Most public schools use traditional methods, while many homeschoolers use a progressive or child-led approach. A traditional education is where teachers set forth specific goals for their class to meet, while a progressive education encourages the children to set their own goals.
Assess the skill level of your child or class. Teachers must assess the reading and math skills of their students, and you may need to work on remedial studies before starting a new curriculum. Typically, third graders need to know how to read and write clearly, and to learn their multiplication tables, addition, subtraction, and more.
Address any issues that specific students may have, such as reading difficulties or not knowing multiplication tables. Set aside time for these students during or after school to meet their needs.
Browse the Internet for suitable curriculum for your class. Use a search engine to locate the right materials. If you already have a curriculum in mind, you can search for extras, such as science experiments or third grade activity ideas. Be sure to keep the age and skill level of your students in mind when choosing which websites to use. Also, choose sites that are reputable, such as those that are associated with universities, other elementary schools or non-profit organizations.
Try out lesson plans found from the Internet on your class. You can also supplement what you found from the Internet with books from the library or other third grade teachers. Once you find a good resource online, check the website for recommended links for you to find other third grade lesson plans.
