I like to choose a set that offers a balance, allowing my kids to grow into their play as they develop their skills.

Variety and Color

Aesthetics matter! I enjoy blocks that come in a variety of colors and shapes. This not only makes playtime more engaging but also aids in teaching color recognition and shape differentiation. I’ve found that the more vibrant the blocks, the more my kids are drawn to them.

As someone who values educational toys, I always look for blocks that promote learning through play. Many 3 2 1 Block sets come with guides or ideas for various construction projects, which can be a great way to spark creativity and encourage teamwork among my children.
