Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Young scholars measure a variety of objects using the appropriate measuring tool. In this measurement lesson, students explain the importance of accuracy and precision in collecting data. They discuss the difference between the two.

Seven activities make up a collection of supplemental materials to reinforce graphing on a coordinate plane. Worksheet objectives include plotting coordinates within single and four quadrants, measuring straight and...

Hold a free-throw shooting challenge in your engineering class! Each team must design a contraption that will fire off a "robot arm" or, more specifically, a catapult, to send a Ping-Pong ball into a basket. Use this as an opportunity to...

Students define accuracy and precision, and differentiate between the two terms, apply the concepts of accuracy and precision to a given situation and correctly apply the concept of significant figures to measurement and mathematical...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

It's time for scholars to show what they know about coordinate planes with a collection of three assessments. The exams' objectives include plotting points on a single grid, measuring using the distance formula, and identifying...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Here is an activity that is intended to highlight a very important issue about precision in reporting and understanding statements in a realistic scientific context. Discuss different ways of reporting the half life of Carbon 14...

Students graph linear http://www.lessonplanet.com/review?id=180542equations. In this problem solving lesson, students calculate slope and plot ordered pairs on a coordinate grid. Using a real-life example of a walk-a-thon, students...

Who knew running a greenhouse required so much math? Amaze future mathematicians and farmers with the amount of unit conversions, ratio and proportional reasoning, and geometric applications involved by having them complete the...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

Agriculture is truly a math-based profession! Help the dairy farmer determine the supplies needed to complete his barn. Using given dimensions, learners build equations and use units to determine the correct amount of materials.

Food companies understand how to use math to their advantage. Learners explore the math related to the packaging and serving size of yogurt. They then use unit analysis and percent values to make decisions on the product development.

Forgive me, I regress. Building upon previous modeling activities, the class examines models using the regression function on a graphing calculator. They use the modeling process to interpret the context and to make predictions...

Learners critique their own drawings for accuracy and make constructive suggestions prior to reworking them. They discover how scale in maps and drawing relate to relative size and distance. In addition, students comprehend the...

Young mathematicians use photos and video clips to determine if a cricket player is "in" or "out." This analysis occurs using scale factors, distance-rate-time formula, and consideration of precision and accuracy.

Students explore approximate and exact solutions. For this interdisciplinary lesson, 6th graders will be placed in 'family groups' to create a budget that is subject to random events as chosen from the 'things happen' box. This lesson...

If you have ever injured your shoulder, you know it takes a while to improve your arm's range of motion. In this real-world example, young mathematicians gain insight into the world of physical therapy while they analyze a case study...

Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

How many points are needed to define a unique parabola? Individuals work with data to answer this question. Ultimately, they determine the quadratic model when given three points. The concept is applied to data from a dropped...

Elementary schoolers learn about metric units and how they are used by engineers. They learn how engineers use the units to measure mass, distance, and volume. Then, they estimate measurements of units, and compare them to actual...
