This is a spin off based on the FOSS curriculum that I have taught with for the last few years. The package includes the interactive workbook pages, a safety contract, an easy to use table of contents, all 4 i- checks, color coded vocabulary cards, and posters to help provide visuals to the key concepts, and a glossary that can be traced to help with building vocabulary knowledge. I also included a sound sort, which my students loved to do.
