How to Choose Building Blocks

Pick a set that matches how your child plays now, and how you want play to grow.

  1. Piece Variety: Look for a mix of cubes, planks and baseplates so children can build towers, bridges and ramps, expanding play options.
  2. Material and Finish: Natural, untreated wood is durable and pleasant to touch, and easier to sand or refinish as needed compared to coated plastics.
  3. Open Ended Play: Choose sets that support different play modes, from free building to guided challenges that promote planning and persistence.
  4. Size and Safety: Check piece dimensions, like the 1.57 inch cubes in this set, to ensure they fit your household safety needs and storage options.
  5. Storage and Portability: A sturdy storage bag or box makes cleanup easier and keeps pieces together for travel or shared play.
