Why the filter in the CMS-page is not changing when I visit other page of the collection?

Hello I have a special question…

I created a schoolyear of 3 trimesters… but there are activities in each trimester.
so I want to filter for each page the activities form a CMS-collection that contains ‘alle activities’

(Is it only possible when you create CMS collection ’ activities trimester 1’ ‘… 2’ ‘… 3’
So maybe somebody knows a solution to dynamicly filter when you change the CMS-page.

also this : the classes that the teacher have… should be filtered on their ‘teacher-page’.

My project I’m working on:
