1 Numerical and Categorical Data 3: Comparing Categorical and Numerical Data Resource Type: Lessons Discipline: Mathematics Grades: Grade 6 Professional Commentary: In this third lesson (in a unit of three) students compare categorical and numerical data by identifying examples of each, using graphs they created in parts 1 and 2 of this unit. Students first analyze the appearance of the two graphs.... 2 Playing Games: The Celebrated Jumping Frog Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–6 Professional Commentary: Using the story "The Celebrated Jumping Frog of Calaveras County" by Mark Twain, students simulate a frog jumping contest and measure the distances "jumped." The students record the distance of individual jumps in centimeters and determine the total distance jumped (the sum of the three separate jumps) and the official distance (the straight-line distance from the... Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–6 Professional Commentary: Students make paper airplanes and explore attributes related to increasing flight distances. Each student collects data from three flights of an airplane and finds the median distance the airplane flies.... 4 Food Court 3: The Clucking Chicken Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–7 Professional Commentary: Students order meals in pairs from a restaurant menu, find the range of prices, and then compute the average price. One student from each pair goes to the front of the room, where they order themselves according to price.... 5 Count on Math 1: Every Breath You Take Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–6 Professional Commentary: In this first of two lessons on developing number sense, each student estimates the number of times s/he breathes in one hour, and the class graphs the estimates, finds the mean and median estimates, and discusses outliers. Students then explore how they might estimate the number of times they breathe in one day and how they... 6 Whirlybirds: Math Grows Up (Statistics) Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: Students participate in a simulation of a parachute jump competition by making paper Whirlybirds, and then dropping them towards a target on the floor. They measure the distance from the point where the Whirlybird lands to the target.... 7 Dealing With Data In the Elementary School Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–6 Professional Commentary: Students design a study and collect data to determine how much garbage in the school cafeteria is recyclable. To design the data collection, students follow a seven-step investigative procedure that can be applied to a variety of research questions, three of which are suggested as extensions of the lesson.... 8 NAEP Assessment Item, Grade 8: Find a median Resource Type: Assessments Discipline: Mathematics Grades: Grades 4–8 Professional Commentary: Students are asked to find the median of an unordered set of eight elements. This multiple-choice question is a sample test item used in grades 4, 8, and 12 in the 2003 National Assessment of Educational Progress (see About NAEP).... 9 Developing Estimation Strategies by Making Connections Among Number, Geometry, Measurement, and Data Concepts: Estimating Scoops Resource Type: Professional Resources Discipline: Mathematics Grades: Grades 1–4 Professional Commentary: Estimation activities encourage students to make connections among the mathematics concepts they are learning and the skills they are developing. In this multipart video illustration, the class discussions and the decisions the teacher makes contribute to students' opportunities to integrate their understandings of number, measurement, geometry, and data.... |
