Hi John,

I believe what you're referring to was part of the old teacher dashboard, which was removed ~3 years ago. From the current teacher interface, there is not a way to view the number of energy points that students have earned within a specific time period. This was removed because energy points were not a very good measure of mastery progress or activity.

As a replacement, the Activity Overview tab was added to the classes to allow teachers to view their student's recent activity and total active learning minutes. For more information on this report and what it shows, please see this article.

I hope this helps! Please let me know if you have any additional questions!
