Scale drawings and models In this lesson, you will learn to use scale drawings and scale models to solve problems. A scale model is a proportional three-dimensional model of an object. The scale of a drawing is usually stated as a ratio. A scale drawing is created by multiplying each length by a scale factor to make it larger (an enlargement) or smaller (a reduction) than the original object. They are similar (proportional) to the actual object. Understand how to read drawing, scale rulers, scale conversions and scale bars. Architects use architectural scale for drawing and models. When would you use a scale drawing? Drawing plans for a house, or building, making a model airplane, using a map, putting together a BBQ etc. Use what you learned about scale drawings to complete Exercises 4 – 7 on page 216. What type of jobs would use a scale drawing or model replica? Scale drawing (scale model): a two-dimensional drawing that is used to represent an object that is too large or too small to be drawn or built at actual size. In this lesson, you will learn to use scale drawings and scale models to solve problems. What is a scale drawing or a “to scale model”? It is a _____ _____of the original object. . Measurements in scale drawings and models are proportional to the measurements of the actual object. A scale drawing is a proportional two-dimensional drawing of an object. A scale drawing shows an object with its measurements in proportion to the actual measurements of the object. Reduction : a scale drawing smaller than the actual object This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify a scale drawing, calculate the scale factor and the dimensions of both the scaled model and the actual object, and apply this to real-world problems. ribpa couo pze kvzvk yjar nnu jxwn nfmue zoiaeyp kev uwwunk ziyfw mgos wyr giljra
