Kelly R:  My son received this as a 6 year old, played with it every single day, and actually still sometimes pulls it out now at age 12. It's been fun over the years to watch him problem solve as he gets better and better at designing the marble runs. The set is heirloom quality, and a variety of other sets and add-ons are available so you can continue expanding the collection.

They will use critical thinking and building skills to put together different LEGO machines that can perform ordinary tasks in an extraordinary way. Kids will build moving LEGO creations that can ring a bell, toss a gum wrapper into the trash, deliver a message, and more! The illustrated instruction book makes building a snap.

Erynn:  Bloxels is a coding and video game design platform that allows kids to build their own video game online or using any compatible device. Kids who have always wished to design their own games will appreciate its simple interface, and even younger kids who are new to STEM will be enthralled. Though the game was originally released with a physical game board that has since been discontinued, you can purchase a Bloxels account to design on the web or using the app for iOS or Google Play.

Sort them by colors, identify the shapes on the sides, practice making patterns, build a tower, and introduce counting and multiplication by packing them together into larger rectangles and counting the number of blocks on each side. While the cubes are recommended for kids 5+, any child that can safely work with small pieces will derive hours of fun from this simple set.
