Please fill in your availabilities for our second common math hike in elu-participants. i created five columns for that and for each day you should write the time-frames when you can play the trail at its location which is not far from the location of the previous trail but not too close either. Free parking is available close to that trail though. That trail is created by the same math teacher who arranged the competition for students of math and integrated sci on 20221108. i have chosen these days because katriin is going to be available during these days.
