Adding Rigamajig to the curriculum

Educators can utilize Rigamajig in many parts of their curriculum. With the help of a few adventurous teachers, this user guide helps educators integrate Rigamajig into their classroom, playground, or playspace.

Design, analysis, and construction make up the core (or heart) of Rigamajig. Form and function are continuously analyzed as children try to create something that satisfies human and environmental needs. Children construct and use simple machines, ponder the concepts of compression and tension, play with balance, and learn about the properties of wood, all the while considering how various parts relate to each other in order to create small systems that perform a multitude of functions.

Children simultaneously practice problem solving while designing and playing with their technological inventions. They create and work with simple machines (e.g. pulleys, ramps, and screws) as a means to create new, more complex machines.

Throughout play, children experience all parts of the invention process: research, comprehension, design, model building, testing, and modification.

Art reaches far beyond creativity, involving observations, prototypes, tests, and changes. Art exercises the parts of the brain that allow children to approach problems with an open mind and think outside the box.

The modularity of the planks helps bring math language into children's play. The parts work together intuitively as units for easy building. Two small planks are equidistant to one large plank, thus embedding geometry within play. Similarly, clean up time is always an opportunity to count and sort.

Social Studies
For young children, social studies is the science of learning to live, work, and play within a community. Rigamajig teaches children to work in small groups, develop social skills needed for negotiations, and find their voice.

Includes 260+ parts, 2 milk crates and cart.
