Big 100 Piece Rainbow Mix - Large Building Blocks for Toddlers | Quiet Stem Toys for Toddlers, Prek Classroom Essentials, Stem Bins for Classroom, Sensory Bins, Gifts for Girls & Boys

This Plus Plus Big Open Play Set absolutely delivers on fun, creativity, and quality—especially for younger kids just getting into building toys. Right out of the box, the neon colors are vibrant and eye-catching, which instantly grabbed my child’s attention. The pieces are perfectly sized for little hands—larger than standard Plus Plus pieces—so they’re easy to grip, connect, and pull apart without frustration. That alone makes a huge difference for toddlers and preschoolers who are still developing fine motor skills. What really stands out is how versatile these simple shapes are. Even though each piece is identical, kids can build in 2D or 3D, creating everything from basic patterns to imaginative structures. It’s one of those toys that quietly encourages problem-solving, creativity, and spatial thinking without feeling like “learning.” The quality is excellent too—durable, smooth edges, and they snap together securely without being too tight. After plenty of use, the pieces still hold up like new. Another big plus is how open-ended it is. There are no rules, no instructions needed (though ideas are included), so kids can explore at their own pace. It keeps them engaged much longer than more structured toys. Overall, this is a fantastic STEM/STEAM toy that combines fun with developmental benefits. If you’re looking for something screen-free, creative, and long-lasting, this set is an easy win. Highly recommended for curious little builders!

Fun size to build with

My kids love these! You can do a lot with them. Durable colorful and ready for imagination.

My students have really enjoyed building with these.

My children really like those and they are a good alternative for younger kids as they are big and cannot be swallowed.

Great puzzle pieces for my granddaughters age 6 and 3. We sit on the floor and build homes, people and animals and have great conversations while bonding! Antler hard for the 3yr old to snap into place but she’s getting there

What a fun toy!! My kids are 15 months, 4, and 5 and everyone likes these blocks. They come in fun colors (we got the neon) and I even throw them in the bath sometimes. Glad someone on instagram suggested these!
