Lesson Purpose

Students will understand and apply scale, similar shapes, and proportional reasoning forming a bridge between scale drawings and real objects.

Students will use the skill learned to plan events by dividing the space to be used appropriately, and by knowing how many tables and chairs are to be used based on the number of individuals attending the planned event.

Scale drawing will assist students in preparing ahead designing the space to be used. Because of understanding scale drawing, students can know exactly how many tables and chairs can be placed in a given space.

Scale drawing is a visual representation of the space.

Lesson Objectives

At the end of this lesson, students will be able to:

Make scale drawings for the professional workplace calculating scales and recognizing similar shapes. Scale drawing, measurements and proportional reasoning, will allow students to effectively use the space to organize events.  

Student Target

I can calculate scale, make a scale drawing, and recognize similar shapes.

CCR Focus Standards

Geometry - Level D

• 7.G.1

  Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. [Also see 7.RP.3]

• 8.G.4

  Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two- dimensional figures, describe a sequence that exhibits the similarity between them.

Supporting Standards

• 7.G.6

  Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.
