Free Rock Activities for Preschoolers Plus Free Preschool Lesson Plans

Preschoolers are fascinated by rocks! My son has pocketed more rocks from the ages of 2-5 than I could possibly count. Actually, I probably could since they end up in the washing machine on a regular basis!
Rocks are so interesting to young children because they come in so many different sizes, shapes, textures, colors, and even levels of hardness. When my son (he was four at the time) discovered that he could use a rock like a piece of chalk to write his name on the driveway, he was over the moon. So when it comes time to teaching this theme in my preschool, kids are always so excited and ready to begin!
Teaching a preschool rock theme is great learning for any time of the year, especially when the weather allows you to get outside on a rock hunt!

FAQ About a Rocks Preschool Theme
You may have a few questions about teaching this preschool theme! Check out these frequently asked questions for how to teach your preschoolers about rocks.
Preschoolers have lots of questions about rocks! Some concepts kids can learn about rocks include the names for different sizes of rocks (pebbles, rocks, boulders, etc), the properties of rocks (such as textures, colors, and hardness level ), and learning about whether rocks sink or float. Of course, feel free to dive into this topic as much as your preschoolers like including learning about gemstones and minerals.
In addition, learning to compare and sort by shape, size, type, or texture or weighing them on a balance scale is a great way to incorporate fun learning into your rock theme.
Learning about rocks in preschool is not only fun but it sets young children up to learn more about the earth and the world around them. Studying rocks introduces children to earth science and invites them to learn more about the evolution of rocks and how rocks can change over time.
Learning about rocks naturally lends itself to discovering more about the earth, environment, and science experiments. Incorporate rocks with this fun gravity experiment or using some pre-k favorite STEM tools to explore.

Literacy Activities for a Rocks Preschool Theme
Pebble Letter Formation – Gather some small pebbles or rocks and print these alphabet formation cards. Invite your preschooler to form the letter by lining up the pebbles to create the letter. Model starting from the top and following the arrow down as you lay the pebbles down. Start by building your preschooler’s name first and then choose random letters. Invite him/her to share the sound that the letter makes and think of a word that begins with that sound.
Letter Stones – Grab 26 stones from the craft store or on your nature adventures. Using alphabet stickers or a permanent marker, label each stone with each letter of the alphabet. Use these stones to label the beginning sounds of things outside, make names, practice short words, or put in ABC order. These are a blast to play with and stack too!
