I have struggled with getting my second graders to understand the concept of a sentence. They either write one sentence that begins at the beginning of the page and ends with the period at the end of the paper or they or they write 2-3 words that are not a sentence but turn it into one by using a capital letter and period. Besides individual conferencing and whole group instruction any other good ideas? I'm finding individual conferencing involves mostly me editing and the student nodding and watching. I know they are truly not understanding the concept this way either. Help!!!
