List what you want to cover for social studies, science, history, language arts, and whatever other subjects you may want to cover.
Step 2: Breaking everything down. For example, you are going to homeschool for 36 weeks in the year. That would be roughly six weeks per continental study if you wanted to give each the same amount of time.
I would want to cover specifics about each such as foods, and traditions, and customs.
The curriculum timeline is the order in which topics will be taught. Sometimes there is a natural progression, but other times you have a lot of flexibility.
I use our library for 95% of our homeschool resources. YouTube is a great resource, as are the streaming services available now. Museums, science centers and such are amazing field trips opportunities.
We often read or watch something and then have a discussion about it.
