Scuba Diving in Belize
ORC# 10354
Resource Information
Resource Type: Instructional Resource -- Best Practice
Discipline: Mathematics
Professional Commentary: In this 5-lesson unit, students take a pretend scuba-diving trip to Belize. They explore various real-world applications of time and distance measurement, make estimations and calculations, and use online resources to plan the trip. In the first lesson, students view several websites and determine what mathematical ideas and concepts are involved in scuba diving. In the second lesson, students use various resources to choose travel dates, compare temperatures, estimate and calculate distances to Belize City, and determine the length of their flight....

What Does It Mean To Measure?: Measurement Session 1
ORC# 11041
Resource Information
Resource Type: Content Resource
Discipline: Mathematics
Ohio Standards Alignment: Grades 3–5, Postsecondary
Professional Commentary: This 4-part unit explores the questions "What can be measured?" and "What does it mean to measure something?" Students identify measurable properties of objects such as weight, surface area, and volume, and discuss which metric units are appropriate for measuring these properties. They also learn that measurement is, by its nature, approximate. Finally, measurements using nonstandard units of area...
