Hello,
I have set up a year schedule for my son. He was trying to check off work he has done and noticed that in the 7th grade Math section under Scientific Notation there is a listing for a lessons or activities called
Let Me Try: Scientific Notation
Reteach: Scientific Notation
Let Me Practice: Scientific Notation

We do not see where these are present in the Scientific Notation lessons. Are we missing where this lesson or activity is within the 7th grade Math section?
