The teacher designed the station so that it would keep going over time by placing small packets of multiple labeling sheets stapled together in the station bucket.
When students go to the station, they take out their packet, choose the sheet they want to label. Then they label the picture, color it, and write a story about what they labeled. Early in the year, students may only write a sentence about the picture they labeled, but as the year progresses, they would be able to add more to their writing. The students work at their own pace and finish what they can during their station rotation. Also, allowing students to choose which picture they want to label from the packet gives them choice, which makes the work more engaging.
Here is a sample of a page from Jennifer's Brown Bear labeling packet.
Check out Jennifer's TPT store, for more labeling packets. Each packet costs about $3 and contains at least 11 labeling sheets. She has packets for fairy tales, fall, and Halloween. Her Label it Mats is a great one to start with because it is basic pictures rather than seasonal items.
