I use this in the very first unit of my 8th grade math class. We are focusing on writing about mathematics and this is a support that I have seen a lot of student growth from. Students are first given time to solve the problem with pencil and paper. Then we check it as a class. Next I show the students my example (which is the file attached). I read them my paragraph out loud. Then I scroll down to show two duplicates of the response. The first one has all the vocab highlighted and the second one shows the sentence starters I used in red. This provides students an example of what level of writing I want to see and how to incorporate the vocabulary and sentence starters.
These supports are especially key for English Language Learners and students that just have a hard time explaining their work. After sharing my example I give the students time to work and then we strategically select students to share out over the class. We also practice how to give peers feedback during this activity as well.
Usually I project my response on the smart-board and then give them a blank version of this worksheet through google classroom.
