Hi, Rachel.

Thank you for your post. I am sorry for the delay in responding. I am a bit behind as I have been away working several homeschool conventions.

For Level F, you will need most of the manipulatives, but not all.

Level F will use the Geometry Solids in two lessons, the Geometry Panels in two lessons and will use the math balance in five or more lessons.

I hope that helps you make a decision on what to purchase.

Let us know if you have any further questions!
Rachel

Yes. That is helpful. Thank you!

My pleasure, Rachel!
