The first step is to consider your child. Although every child needs to know the basics, every child is also unique in his abilities and interests. Before implementing a specific curriculum, observe your child. Try to determine what direction your instruction might take in response to your child's personality.
Every child has a unique combination of strengths and styles, but generally learning styles fall into one of three styles. A visual learner tends to process information through sight, an aural learner processes information through hearing and a tactile (kinesthetic) learner processes information using touch and movement.
Research different curricula. There are hundreds of ready-made curricula available. Talk with other homeschoolers to see what they have found works, what they like and what they dislike. A complete curriculum can make the job easier by providing everything that is needed and guiding you along, but they can be costly. Look for curriculum companies that offer trial periods. Also look for used curricula. Other homeschoolers may have purchased curricula that didn't work for them and will sell them at a good price.
Many homeschoolers find that as they progress in their homeschooling process, they begin to create their own curriculum. Remember, homeschooling can be what you make of it. Find some resources that give you an idea of what a child should learn at each age, then feel free to create lessons that fit your child and your family.
As your child progresses, remember that it is important for your child to master the basics no matter what style or process you decide to use. The ability to read, write, speak properly and do basic math will be important no matter what or how your child studies.
Keep in mind that what works now, may not work next year. A child may need freedom to explore and enjoy the world when she is younger, but need more structure as she gets older. One child may read early and love it, another may take much longer to get the hang of it. Be flexible, and enjoy the journey.
