The troughs and blocks are great for problem-solving, social skills, and gross motor skills. The children can problem solve and motor plan how to best join the troughs together in order to make a waterway. Natural loose parts are often used to manipulate the heights and angles of the troughs. Children can work on their own or within small groups. This is a great activity for children of all ages and abilities. The troughs come in 3 lengths: 14 inches, 2 feet, and 3 feet. Digging and mixing are also part of this activity.
