When is the appropriate time to shift activities

Scenario:
I feel that too many shifts in activities may lead to an overload for my student. I am struggling to find the right time to make an activity shift because I don’t want my student to get frustrated. I am also worried though, that if I constantly shift to new activities that I may not be spending enough time on any one objective.

Possible Strategies :
A shift in activity is beneficial only if each different activity is reinforcing the same language concept. It can become “overload” material if each activity shift is teaching something different, so be sure that your shifts are designed to reinforce what you have been working on in an different manner rather than trying to switch the entire focus of the lesson. It is important that you concentrate your efforts and target specific skills.
