The student will complete a task where they are given 50 feet of fencing.  They have to design the largest area of garden using all of the fencing.  Students must explore circles, right triangles, and rectangles.  Students will be using the formulas of area and perimeter and circumference to calculate perimeter and area.     This task was created with Jamboard to allow students to collaborate together in person or remotely, in real time, as well as allowing the teacher to view students' work in progress.   The initial slide presents the task and provides the formulas for each shape’s area and perimeter.  The subsequent slides provide workspace for students’ thinking and collaboration.  The last slide is a conclusion slide.  Here students tell which shape they chose, give the measurements, and justification

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.

This learning resource provides students insight into combining and subdividing figures as well as utilizing the understanding of quadrilaterals.  Along with the exploration, students will be developing critical thinking through the decisions that are made to create the final mathematical product.  They will also communicate through collaboration to produce a final mathematical product.  They will also develop creative thinking and citizenship by producing a written piece to show their caring and understanding nature.

Working as a team, students discover that the value of pi (3.1415926...) is a constant and applies to all different sized circles. The team builds a basic robot and programs it to travel in a circular motion. A marker attached to the robot chassis draws a circle on the ground as the robot travels the programmed circular path. Students measure the circle's circumference and diameter and calculate pi by dividing the circumference by the diameter. They discover the pi and circumference relationship; the circumference of a circle divided by the diameter is the value of pi.

Students learn that math is important in navigation and engineering. They learn about triangles and how they can help determine distances. Ancient land and sea navigators started with the most basic of navigation equations (speed x time = distance). Today, navigational satellites use equations that take into account the relative effects of space and time. However, even these high-tech wonders cannot be built without pure and simple math concepts — basic geometry and trigonometry — that have been used for thousands of years.

This video is meant to be a fun, hands-on session that gets students to think hard about how machines work. It teaches them the connection between the geometry that they study and the kinematics that engineers use -- explaining that kinematics is simply geometry in motion. In this lesson, geometry will be used in a way that students are not used to. Materials necessary for the hands-on activities include two options: pegboard, nails/screws and a small saw; or colored construction paper, thumbtacks and scissors. Some in-class activities for the breaks between the video segments include: exploring the role of geometry in a slider-crank mechanism; determining at which point to locate a joint or bearing in a mechanism; recognizing useful mechanisms in the students' communities that employ the same guided motion they have been studying.
