These drawings are Plan View (birds-eye view) Blueprints, as if you are looking down from above on a dollhouse with the roof off.
You can use a different format to design your room or house, but plan view is useful because you can show all the spaces and furniture.
Most blueprints today are actually black and white. These students chose to add color.
Working on Projects at Home is different than working in school. We do not give you lessons or directions. We give you models of each project to look at carefully, and then you decide how to adopt the project for your interests, skills, materials, time, and any new ideas you have. Your project does not have to look like the models—it can be inspired by the models. If you are proud of what you created, we encourage you to share it online with the hashtag: #ProjectsAtHome
