This is my first post on here and I'm hoping some experienced EYFS teachers can share some wisdom or ideas to help me with my Reception class this year. I am still fairly new to teaching having completed my NQT year only a few years ago. My class this year have a lot of complex needs but in terms of behaviour for learning I haven't really had a problem in general in terms of lessons like phonics, maths or topic. They are all engaged during activities and most show good attention during carpet time because they enjoy the activities and I have used a lot of positive praise to excite their interest in learning. However I am finding specific areas of the day (perhaps less related to academic learning) incredibly challenging with this particular class that I have not encountered previously. For example during Tidy up time, I always have a large group of children who will be fully engaged in an activity but as soon as I stop the class and tell them it is time to tidy up, decide to jump on eachother in the middle of the classroom. I have used lots of positive praise, singing songs to promote tidying and praise those who are helping, had circle times about the importance of tidying up and I have even given these children jobs during this time to keep them busy. But the second my back is turned or I am talking to another child they have abandoned their task and are on top of eachother again. I am fed up and frankly exhausted spending these moments with my eyes on them constantly to make sure they are on task. The second part of the day I am finding challenging is during the end of the day when my TA goes on a 15min break and the children are given fruit and sat down to watch a video on the interactive whiteboard while I read with a small group of them. It is almost like because I am at the back of the class they think I cant see them. Whilst I am at the front the behaviour is not a problem because I can nip any low level disruption in the bud before it escalates. But when I am reading with a group and they cant see me directly some of them start to wrestle and jump on eachother. I really struggle having a solid 15mins with my group without being interrupted by silly and unsafe behaviour from the rest of the class. Again I am exhausted reminding them on a daily basis that I am still there and the expectations for behaviour. I have had the same structure in previous years and this 15min reading time has never been a problem. In addition I have been told that during my PPA, and on occasions my class has been covered by another adult, the wrestling and jumping on eachother behaviour happens more often and other teachers do not know how to manage it. They remind the children about expectations and they stop, but 10 seconds later they do the same thing. Cover teachers have asked for my advice but I am not sure how to get the children to understand they need to respect other adults when I am not there. Does anyone have any ideas to keep the children on task in these moments, and to instil an understanding of why they shouldnt jump/ wrestle in the classroom at any time. I should add that my TA has taken a 6 week leave of absence and I have had a revolving door of supply TAs since October. The inconsistency of additional adults in the classroom has absolutely contributed to the decline in behaviour when I am not there but I am unsure how to tackle this. Like I have said, phonics lessons and maths lessons are great. It just seems to be when there isn't an activity to engage them. Of course we still need moments like tidy up time, guided reading and fruit time during the day so I am at a loss and would appreciate any advice from you lovely and more experienced lot. Thank you for any helpful response and I apologise that I went on a little rant there.
