Our seventh graders recently completed their "Calder Mobiles" project, an activity in which boys are challenged to create a mobile from everyday objects, be they toy cars, keys, boxes of tic tacs, even sneakers!
To create the mobiles, the boys first need to determine a design that will allow the elements used to find balance by applying appropriate rules of mathematics, including the consideration of the mass of the objects and distance from the center.
Once the design is complete, the boys proceed with building their creations, which they then test. This type of activity, which involves real world application of math, is so important in increasing boys' comprehension and mastery of fundamental mathematical concepts. It's also a lot of fun!
