Here are some of the blueprints my 4th graders made during our 3-week Dream House Project. The students began by creating a two-dimensional floor plan on a 38 x 24 square grid. They then calculated the area of each room, determined flooring costs, and transferred the floor plan onto this larger blueprint paper. On this paper, the kids measured the angles in their gardens, swimming pools, courts, and walking paths/dirt bike trails. Finally, everyone colored in the various parts of their property.
