Any one got any good ideas how to teach this. I have been using new collins primary maths and my kids just not getting the recording. They can tell me that 20+23 is double 20 and 3 more (eventually) but recording it has totally driven me mad today. They all did it on the board, we did it practically yesterday and this morning, i drew it and they could do that but once asked to record other q's (double 10 and 20 for HA, and double 5 for LA)some just couldnt get it. I have 2 EAL chn and they managed to get it. The trouble is they just chat constantly. They tell me what they have to do but by the time they go and sit down, have a chat to a few people on the way, have a gorp out of the window, talk to someone else on the table and actually come to get on with the question, they have forgotten what it is they were supposed to do. Then they come back to me and interrupt while im trying to help someone else. I constantly stop the chn and demonstrate again, have various examples on the board showing them exactly how to set it out, which they then ignore. I felt like I was banging my head against a brick wall today, with no in class support either. The chn who got it, were then having to wait around for the other chn to finish, so worked in role play and small world area, but they got noisy so i had to keep asking them to be quiet so the other chn could work! What a day and I just dont know how we can move on to the next lesson if they are still unsure! HELP PLEASE!!!
