Resource Type: Lessons Discipline: Mathematics Grades: Grades 5–7 Professional Commentary: Students learn about sampling bias by working in three separate groups to survey students, parents, and teachers about the amount of homework students ought to have. They report and compare the responses from each of the three groups to see how the results differ.... 2 What's in a Name? 3: Creating Pictographs Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: Students collect data on the number of vowels in their full names and depict the data in pictographs, first with stars that represent one student each, then with stars that represent two or three students each. Discussion questions, suggestions for assessment, and questions for teacher reflection are included.... 3 Food Court 1: The Bread Basket Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: Students create a bar graph from data in a chart. They then collect their own data on classmates' sandwich preferences and create another bar graph using either the supplied bar graph template or an online applet.... 4 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... 5 Numerical and Categorical Data 1: Categorical Data Resource Type: Lessons Discipline: Mathematics Grades: Grades 1–3 Professional Commentary: In this first lesson (in a unit of three) students represent simple categorical data in two ways. They investigate what colors are the eyes of the students in the class.... 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.... 7 Food Court 2: The Soup Spot Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: Students collect data on classmates' soup and salad preferences and create a line graph depicting the data. Then they create a pictograph of the same data using one star to represent each student.... 8 What's in a Name? 2: Last Names Next Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–6 Professional Commentary: Students collect data on the number of letters in their last names and construct a class bar graph to depict the frequencies. They discuss the range and mode of the data.... 9 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... 10 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.... |
