My first experience with Thinkport was doing their online interactive "Pathways to Freedom: Maryland & the Underground Railroad." It was an amazing resource to use while teaching slavery and the Civil War. I used it both when I taught 3rd grade and a few years later at another school when I taught 5th graders and it fit once again in the curriculum.
But this is just a fraction of what is available over at Thinkport. If you have never investigated this resource, put it on your list for the year ahead. Learning resources abound! Be sure to browse by the grade level bands. Within each category you will find an assortment of activities under these topics:
literacy, math, science, social studies, and STEM. You might also find some additional topics such as social & emotional skills, digital tools, digital literacy, or resources for teachers, depending on the age level.
Primary Sources Inquiry Kits for Middle and Upper School for US History and World History. There are also some other great primary resources to other websites along Thinkport's right hand sidebar.
