A scale drawing is a drawing or illustration of a real object which has been reduced or enlarged from its original size, but still proportional to the real object. The proportion by which the drawing of an object is reduced or enlarged is referred to as the scale ratio. 10. Instruct students to place a red block on the illustration in example 3.
scale ratio. Instructions: Place a red block on the illustration in example 3. Observe how the block and the illustration of the block are the same dimensions (length and depth are each 2 cm). The scale ratio of this illustration is 1:1, which means it is a full-scale (full- size) representation of the real object.
EXPLORATION 1. Creating a Scale Drawing. Work with a partner. Several sections in a zoo are drawn on 1-centimeter grid paper as shown. Each centimeter in the drawing represents 4 meters. Math Practice. Analyze Givens. How does the information given about the drawing shown help you create an accurate drawing in part (d)? a.
Maria is making a scale drawing of her bedroom for her math class. She is drawing it on centimeter grid paper. Her bedroom is 12 feet long by 9 feet wide. She is using a scale of 3 cm = 1 foot. How many centimeters should she make the length and the width of her bedroom? S Underline the question.
Sometimes the scale in a drawing is described using a ratio. A ratio strip is a double number line where equivalent ratios can be easily identified. You will use the ratio strip to interpret drawings using a scale of 2 cm : 9 ft. 1. Here is a drawing of a garden that was created using the scale 2 cm : 9 ft. Use the
A scale drawing is a proportional, two-dimensional drawing of an object. A scale model is a proportional, three-dimensional model of an object. Scale The measurements in scale drawings and models are proportional to the measurements of the actual object. The scale gives the ratio that compares the measurements of the drawing or model with
