Adding existing output column to a current query

In the following code, I have need to develop an output column that shows the number of [ActivityName] for each activity.  That new output column would be called [ActivityCount] This needs to be done without losing the existing output.  Essentially if basketball is listed 5 times, then each row for ActivityCount would say 5 in it.

With CTE_Hours as
( select distinct H.AgencyID, H.Agency, H.Classification, H.Objectives, H.Advocate, H.AdvocacyType, H.ActivityID, H.RegID, cast(H.ActivityDate as Date) ActivityDate, H.Fiscal 
  from tblOrgHours H 
  inner join tblOrgRegistrations R on H.Regid = R.RegID and R.AgeCurrent between 11 and 999
  where H.[Hours] > 0
  And H.Agency = 'Administrator'
  And H.Fiscal = 2018
  And H.ActivityDate >= '20170101'
  And H.ActivityDate < '20180101'
) 
select  H.Agency
       ,A.ActivityName
	   ,H.Classification
       ,H.ActivityDate
	   ,H.Objectives
	   ,H.Advocate
	   ,H.AdvocacyType
,max(I.[Tot Individuals for Activity]) [Tot Individuals for Activity]  -- total distinct ID's
       ,Count(H.RegID) as [# individuals]                                            
       ,SUM(CASE when R.AgeCurrent >= 11 and R.AgeCurrent <= 13 then 1 else 0 end) as [Ages 11-13]
