Through this lesson and its two associated activities, students are introduced to the use of geometry in engineering design, and conclude by making scale models of objects of their choice. The practice of developing scale models is often used in engineering design to analyze the effectiveness of proposed design solutions. In this lesson, students complete fencing (square) and fire pit (circle) word problems on two worksheets—which involves side and radius dimensions, perimeters, circumferences and areas—guiding them to discover the relationships between the side length of a square and its area, and the radius of a circle and its area. They also think of real-world engineering applications of the geometry concepts.

What types of 2D and 3D shapes make up the products all around you? This challenge will explore how different shapes can be put together to create a product. All the products that humans design and produce are a combination of different shapes. To design a product, engineers and designers must understand how combining, subtracting and adding shapes can make new and unique objects. This challenge will have students use a 3D design tool to create a new and unique shape.

This is a 60-minute lesson that includes a self-paced interactive module and classroom activities. The teacher guide includes a challenge sequence (timeline), relevance to standards, materials list, assessment, resources like cut-outs template, and learning extensions.

Lesson objectives: (1) Explore and interact with 3D shapes in a design plane. (2) Compose unique 3D shapes by decomposing other shapes. (3) Build a 3D shape from a 2D net.

In this 20-day module students explore area as an attribute of two-dimensional figures and relate it to their prior understandings of multiplication. Students conceptualize area as the amount of two-dimensional surface that is contained within a plane figure.  They come to understand that the space can be tiled with unit squares without gaps or overlaps.  They make predictions and explore which rectangles cover the most area when the side lengths differ.  Students progress from using square tile manipulatives to drawing their own area models and manipulate rectangular arrays to concretely demonstrate the arithmetic properties. The module culminates with students designing a simple floor plan that conforms to given area specifications.
