I'm trying to get better about actually completing projects that I've pinned on Pinterest.
I came across a fun LEGO marble maze on Pinterest earlier this week (pinned from Detroit Mommies). I knew immediately that this project would have to be added to the kids summer fun list. I showed it to them and they immediately set to work, each armed with a pile of LEGO and a square green LEGO board.
This kid though likes to keep things simple.
Alternatively, cut square boards into quarters. Package each board with a collection of LEGO pieces and a marble so kids can build their own LEGO marble mazes. These will make great party favors.
