Designing and playing with wooden blocks of all kinds can be lots of fun. Sometimes it’s nice to use a frame to give yourself a specific space in which to work. A wooden serving tray with raised edges works well as a frame for playing with square color tiles, Cuisenaire rods, or pattern blocks.
Small cardboard boxes with low edges are good for Cuisenaire rods and color tiles.
A hexagonal plant stand with raised edges works as a great frame for pattern blocks.
