GRADES 7 and 8

Suggestions for Getting Started

Click on a prompt to get either (1) an enlarged pdf that you can display or copy, or (2) a page of supporting notes. I am working on writing supporting notes for every prompt, but this will take time. Feel free to request prompts that you would like me move to the top of my list!

Notice that

*Creative Math Prompts*do not have directions. You and your students decide what questions to ask. Prompts that have supporting notes will give you some ideas, but don’t be afraid to explore the prompts that don’t have notes yet!Watch for prompts that make connections across topics. They appear in more than one content category.

Explore beyond your grade level. Depending on your students and your curriculum, prompts from one or even two grades before or after the grade you teach may sometimes work better than the ones listed here! Also, the prompts are very open-ended, so you may be able to continue using prompts that have already been used by teachers at earlier grade levels!

Please contact me if you have a new idea for a Creative Math Prompt, especially for the few content areas that lack one. I will give you credit!
