Week 7 - Cardboard Intro & Treasure chest

First graders are moving on from yardstick to building with the greatest of all building materials, corrugated cardboard. We began with practicing a few basic attachment techniques from our cardboard attachment chart. 

Once we got comfortable with the l-brace, tabs, and slots we put our newfound skills to work and built little treasure boxes. These rely primarily on using l-braces and are also a great way to begin talking about shapes and construction.
