⭐️⭐️⭐️⭐️⭐️ Beth said, “My students love a great graphic organizer to study the overall formula list. This resource gave LOTS of options for me to use with them! I love that there are blank sheets as well as sheets that are filled in. It is also great to have a black/white option to make copies, but I printed to color copy to have in my classroom!”
