Resource Type: Instructional Resource -- Best Practice Discipline: Mathematics Ohio Standards Alignment: Grades 3–5 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.... 2 Ideas with Food: A Brownie Bake Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 3–5 Professional Commentary: Students do some mathematics in preparation for making brownies. They consider the inverse relationship between the base area of two different sizes of cake pans and the thickness of the same volume of batter poured into each pan.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 2–4 Professional Commentary: Students measure, record, and graph plant growth and interpret data. Students plant seeds and, once the seeds sprout, record the height of the plants for several days.... 4 NAEP Assessment Item, Grade 4: Convert a quantity of pints to quarts (calculator available) Resource Type: Assessment Resource Discipline: Mathematics Ohio Standards Alignment: Grade 4 Professional Commentary: Students are asked to convert 6 pints to quarts, given that 2 pints equal 1 quart. This multiple-choice question is an "easy" test item used in grade 4 in the 2007 National Assessment of Educational Progress (see About NAEP).... 5 What Does It Mean To Measure?: Measurement Session 1 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... 6 NAEP Assessment Item, Grade 4: Find the Box With the Fewest Balls Resource Type: Assessment Resource Discipline: Mathematics Ohio Standards Alignment: Grades 2–5 Professional Commentary: Students must determine which of three boxes of equal size will hold the fewest balls when filled with balls of different sizes. This multiple-choice question is a sample test item used in grade 4 in the 1990 National Assessment of Educational Progress (see About NAEP).... |
