Resource Type: Lessons Discipline: Mathematics Grades: Grades 6–7 Professional Commentary: This 3-lesson unit provides students with an introduction to many basic concepts in probability. In Part 1, Talking Probability, students focus on the language of probability as they use their life experiences to recall events that are certain, impossible, likely, or unlikely to happen.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 6–7 Professional Commentary: Students are given 15 chips and a number line labeled from 2-12. They are instructed to place their 15 chips on the numbers that they think will represent the sums when two dice are rolled.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 6–8 Professional Commentary: First, students review Pascal's Triangle by completing and discussing the entries of the first eight rows. They then determine the total number of possible girl/boy combinations in a five-child family.... 4 Understanding Probability Resource Type: Lessons Discipline: Mathematics Grades: Grades 6–8 Professional Commentary: Students learn the basic definition of probability and how to express it as a fraction, decimal, or percent. They compute probabilities in a variety of real-world contexts.... 5 Pizza, Pizza! 2: Favorite Pizza Toppings Resource Type: Lessons Discipline: Mathematics Grades: Grades K–2 Professional Commentary: In this second of three lessons related to pizza, students work in small groups to color pictographs to depict the group's favorite pizza toppings. Two different methods of data collection are suggested, and some groups may come up with other methods.... 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.... 7 Probability with a Random Drawing Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–4 Professional Commentary: Students repeatedly draw a block at random from a bag containing two red blocks, two blue blocks, and one yellow block, replacing the block and shaking the bag after each draw. Students keep track of results and after several trials, they conjecture how many blocks of each color are in the bag.... Resource Type: Lessons Discipline: Mathematics Grades: Grade 5 Professional Commentary: This two-day lesson is a conceptually and contextually rich introduction to informal probability. Students play a game to learn about the four forces that affect flight: lift, drag, thrust, and gravity.... 9 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.... 10 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.... |
