This is a fun, engaging, and hands on way to teach kids about the 3D shapes. This hands-on activity, is a great way for kids to begin developing engineering skills. They will love using marshmallows, or other appropriate treats, to create their own 3D models, so you may want to have extras on hand, as a reward for finishing the task! Children will not only have fun while constructing 3D nets, they will also learn to follow instructions, and even gather the appropriate materials for the project.
