Last year I bought the apple peeler from Bed, Bath and Beyond for around $15. It is really easy to use and is suctions to the table. I bought the clear cutting mats from the Dollar Store and used disposable plastic knives for the kids to dice the apples with.
Each child peeled and cut an apple to add to the crockpot. We used a variety of apples. I had asked students to bring in apples the week before. We had Granny Smith, Red Delicious, Gala, Fuji and a few others. Once all the apples were added. (I added a few more about 25 total) I added about 1 cup water and a tablespoon of sugar. I then turned the crockpot on high. I stirred the apples about every hour. This year I had to leave school early, so I place the crockpot into a plastic file crate, it fit perfectly, and took it home to finish cooking. I used my Braun hand blender to puree the sauce once the apples had cooked.
I rotated the students through the applesauce making station. When they weren't busy peeling and dicing apples, they were busy tearing and gluing paper to make their torn paper apple.
I am so happy with how these came out and my kids had fun making them.
If you would like to make them, just grab the pattern and directions for free from my TpT store.
