The maximum number of pages a student can manage is default to 5. An Administrator can change this default by navigating to Configuration-> Working environment and change the "number of pupil pages".
Managing Student pages is a 3 step process
Step 1 is setting up Student Pages by navigating to Configuration ->Pupils & Groups. Select Year Group and Student in year group. Please make sure you set "Publish Page" to status "Approve" for the Teacher to have final publishing rights
Step 2 is for Students to login via the Student Portal and to add content to their pages. Each Student will have their own pages.
Step 3 is for the Teachers to approve pages and contributions made by Students by login in to the Teacher Dashboard
