This is a great sensory activity. So many opportunities to build and use language and math skills. Great for exploration. My three year old son loves it. Theres a variety of activities you can use them for.

We purcahsed these for our classrooms in our Child care facility. They are a fun addition to our science/sensory area. They are pretty sturdy too. The children teachers like them.

Got these to use in kinetic sand in preschool groups. Realistic.

The kiddos love these for all kinds of activities: sorting, counting, art.... They are great in our sensory tables as well! Great purchase!

I had been looking at these for some time in a nature catalog. I decided to purchase through Lakeshore because I am always happy with the quality of their products. Shells are well made and serve well as sensory materials. They clean easily and can be used to make prints in sand, in paint, etc. Good amount, multiple sizes and textures, etc.-happy with the product in my preschool classroom.
