 * //Making a scale drawing of your bedroom: Scale it!//**

Students will demonstrate their knowledge of writing and solving proportions by creating a scale drawing of their bedroom. The teacher will demonstrate several ways to solve for an unknown in a proportion. After guided practice, the students will have access to computers and a proportions self- help sheet. The sheet will provide links to a variety of web sites for them to choose from. The sites will provide further examples of everyday uses of the skill, including photography, reading maps, and blue prints. Finally the students will create a scale drawing of their bedroom.

Day one: in class instruction and guided practice

Day two: computer lab independent proportions self-help

Day three: in class instructions, examples, and directions on creating a scale drawing

Day four: write and solve for the scale measures of their rooms

Day five and six: create the scale drawing and complete the handout
