We are studying a unit on "Architecture" for 3rd and 4th grade. I wanted to start out with something that would review using a ruler, our imagination and basic shapes.
I made a very quick power point showing different castles from around the world, had different castles terms defined, and then spoke about what we would be doing.
They used rulers to create straight lines, they were to draw their castle anyway they would like. I showed a brief demonstration on rulers, basic castle shapes, how to draw a drawbridge, etc. and then said add "your own flare/creativity". They had a texture sheet on how to add different textures such as, bricks, stones, polka dots, checkerboard, etc.
We used a 11" x 17" white constructions, drew in pencil line, outline with sharpie markers, and colored in with crayons or markers.
Check out these amazing castles! ( did see some cool castle design projects on Deepspacesparkle and ms.julie's art school)
I really wanted the students to feel like real building designers and architects!
