Good for many ages and both genders
I'm a homeschooler constantly trying to find ways for my 3 year old to be entertained while adding educational value. This was perfect for her (and would be appealing to either gender). Keeps her entertained forever, she loves playing with the jewels, uses shapes, colors, and hand eye coordination. The "rocks" easily snap together by you or your child and hold the gems, they wedge the screwdriver in the hole and bop it with the hammer. The rock "cracks" open to reveal the gem. Well done! I love this brand. Even my 8 year old boy played along.

Fun, Educational, and Perfect for Early STEM Skills
The Learning Resources Rock 'n Gem Surprise Activity Set is a fantastic learning tool for young children. It’s engaging, colorful, and provides a hands-on way for kids to develop sorting, matching, and counting skills. My 2.5-year-old daughter loves it, and I can see how it helps her build important cognitive abilities while having fun. Pros: Bright and Engaging Design: The vibrant colors and shiny "gem" pieces immediately capture a child’s attention. The different shapes and sizes of the gems make sorting and matching activities exciting and visually stimulating. Educational and Developmental: This set is great for teaching early math skills like counting, sorting, and comparing. It also introduces patterns and sequencing in a fun and interactive way. Durable and Safe Materials: The pieces are made from sturdy, high-quality plastic that feels durable and safe for little hands. There are no sharp edges, and the gems are large enough to prevent choking hazards. Versatile Learning Opportunities: In addition to sorting and counting, we’ve used this set for imaginative play. My daughter loves pretending she’s a treasure hunter or jeweler, which adds an extra layer of creative fun. Compact and Easy to Store: With just 19 pieces, the set is easy to store and doesn’t take up much space. It’s also lightweight, making it perfect for travel or playdates. Cons: Limited Number of Pieces: While the 19 pieces are sufficient for basic activities, adding a few more gems or additional shapes would increase the variety and extend playtime. Slightly Simple for Older Kids: For children closer to the upper age range (5+), the activities might feel too basic. However, you can introduce more advanced concepts like simple addition or subtraction to keep it challenging. This activity set has quickly become a favorite in our home. My daughter enjoys sorting the gems by color and shape, and I’ve noticed her improving her counting skills. We also play matching games, which keep her entertained and focused. It’s a great toy for independent play as well as parent-child interaction.

Exciting, Educational, and Mess-Free Fun!
This Rock ’n Gem Surprise set has been a fantastic addition to our playtime! My child loves using the play hammer and chisel to crack open the reusable geodes and discover the colorful gems inside. It’s a fun way to introduce sorting, matching, and counting skills, as each gem comes in different shapes and colors. The set also offers a gentle introduction to geology concepts without the mess of real rocks and geodes. The included drawstring bag makes cleanup and storage a breeze. Highly recommend this engaging and educational toy for young learners!

Great toddler toy
Bought these for my 2 year olds birthday and he LOVES them! His occupational therapist uses them so I knew I couldn’t go wrong. But seriously, such a cute toy and keeps my son actually entertained. The gems are small so you definitely have to keep an eye on smaller toddlers, but I’m sure that’s why the age says 3+. They’re very durable and great quality. My son loves the vibrant colors and shapes.

Kid Approved
My kids are obsessed—this has turned into nonstop playtime since we got it. They love hiding other small items inside and discovering them again, which keeps them engaged for ages. It’s great for color matching and really helps with understanding cause and effect in a fun, hands-on way. Educational without feeling like “learning,” and honestly one of the toys they keep going back to. Highly recommend!

Great product!
Update 12/26: Christmas has come and gone, and this set has got PLENTY of play! It was a huge hit for my son, who is extremely picky about his toys. He has sat and played with this for hours, usually 30 to 45 minutes at a time. He loves using the tools, and prefers to identify the shapes rather than colors right now, but he still keeps them matched up correctly. I highly recommend this awesome and incredibly fun toy. You and your child both will have a blast playing with this set! I bought this set as a Christmas gift so it has not yet been played with, but I already know my (almost) 4 year old is going to have a blast with it! There are so many ways we'll be able to play with this, while educating him. Since he is not going to preschool, at-home education is very important to us, and fun props are always welcome! Every piece in this set is large and chunky, making it easy for hands of all sizes to manipulate the pieces, however, using the pick to open the geodes helps with fine motor skills. Each gem's color matches the inside of a geode so it's great for color matching. Could work as a memory/matching game, and could work for teaching about actual geodes, too! So much potential for learning, in such a fun way! Everything seems to be made extremely well, the colors are perfect and vibrant, and the little bag for storage is very much appreciated! Of all the Christmas presents we've bought this year, this one has got to be my favorite.

One of the best learning resources toys!
The Learning Resources Rock 'n Gem Surprise set is a gem in our home learning, captivating my daughter with its blend of colorful gems and educational activities. The “rocks” are the perfect size for her little hands to grasp, and she loves “mining” to get the gems out. Considering how much she has been using this toy, it’s pretty impressive it’s held up so well. She loves sorting her “gems” when she is done by color or shape. It perfectly merges her fascination with nature and early STEM learning. The excitement of uncovering hidden gems within the “rocks” adds an element of surprise that keeps her eagerly engaged. As she manipulates the pieces, her fine motor skills and sensory abilities are honed, and watching her learn and grow with every play session is truly rewarding. This 19-piece set not only brightens her day but also lays a solid foundation for critical early STEM skills in a fun and interactive way allowing her to learn as she plays! Highly recommend!
