While collecting and selecting materials, think about what kinds of construction you hope to explore. For example, cardboard and paper can be cut with scissors and decorated with markers to make a build personally meaningful. Straws or masking tape can make for flexible connections and movement.
Types of materials fall loosely into 3 categories: raw materials, connectors, and tools. Below are ideas for starting points in each category.
Pro tip: Choosing a material from one category and using it as another can result in exciting discoveries to push your construction further. For example, we normally think of cardboard as a raw material. Asking "how could we use cardboard as a connector?" opens up new possibilities.
