Hi Shelia,
See page 14 in the manual. Others might be able to add their input in regards to how long interventions take. Many people have allotted times for interventions and possibly add generalized practice if they need additional activities.
Please let me or others know if you need additional details.

I had a question about length of interventions. Is there recommended times for each of the interventions? This was brought up during a conversations related to intervention integrity.
