While teaching SOL 7.6 (proportions), I use an activity for scale drawings. The students work in groups of two and have to produce a scale drawing of the classroom. The first step is to make a simple sketch of the room. They use this sketch to record their measurements of the room. Once they have completed all measurements, they have to use proportions to come up with the
measurements for the scale drawing. I used the "window" method for proportions this year. "K" is what you know; "?" is what you are calculating; and the units go on left side. You can easily differentiate this activity by adding more details in the room (desks, shelves, computers, etc.)

Very practical and hands on. I like the chart as a way to organize the information.
ReplyDeleteI like the idea of the chart to organize the porportions. This chart could be used with a variety of other lessons too.
