Englis access course 2nd class

On Monday, I had my second class with these special students from the English access course. I said special because they are wonderfull on carrying out the activities. I got a little late because I had classes before and then I had to run to the rooms that are in the court, but I got there to do my job. I had planned a warm-up activity which at the last moment I did not do.. I change it and the new one worked really nice as students  were eager and enthusiactics carrying out the activity.I developed some activities by using  a song called "because you loved me" which was very useful for me as my topic was irregular verbs and it contains mane of them. While doing a fill in activity, I could notice some students were singing the song, so at the end I had them sing the song. I divided them into two groups, each of them were to sing a stanza each, and it worked nice. They really liked it. The only problem was that I took   too much time on this, and it was marked in the feedback part. The activities I developed were to have students practice in an oral and written form the irregular verbs in the simple past form, so I planned activities for them to write the verbs, and then I had them say the verbs. There was another activity in which students were to say a sentences by using the verb I provided. They actually did it but in the feedback I was suggested to do it in a different way which I consider can be more benefitial for the teacher and for the students as well.  This suggestion was to give students a verb, given them time to think and write the sentence, and at last to have them say their sentences..
