I will note that my child is slightly advanced and a "typical" first grader may not be ready for this work, but that doesn't mean you can't be successful. Truly, this is my daughter's second year of formal education as I started her on formal work during Kindergarten. If your child can read a little bit, hold a pencil and understand basic math (addition and subtraction), then this is the first grade program for you.
This year we will master reading and writing. We will also be doing an extensive investigation into U.S. History, geography concepts, biology, earth science, physics, chemistry, and anatomy. Other topics will be approached. You can take a look at the curriculum here. It is also in the drop-down menu under Educate.
