The marble run toy is a great toy to build imagination. I can see my preschoolers minds really turning as they play with this great toy. I like letting them play with this because many great conversations are started while playing with this, such as I wonder how fast it will go and will it work if I do this?
This is a toy that is intended for older preschoolers. Since it does us marbles, there is a choking hazzard so it is best to use it with 5 year olds plus. I have seen many of my four year olds use it well, but I am always watching them. IF you can not be right there with them, forget this toy for children under 5.
Some of my younger preschoolers have trouble getting the pieces together so my help or an older preschoolers is often needed. But once we get the creation built, my preschoolers have so much fun watching the marble roll down and around the track, racing faster and faster until it reaches the bottom. This is definetely a great toy for older preschoolers.
