Making a Table Leo and Sally used the two spinners shown. They spun the pointers and recorded the sum of the two numbers. They spun 20 times. Their results were: 2, 4, 6, 5, 4, 5, 4, 4, 2, 4, 4, 3, 4, 5, 6, 4, 6, 4, 3, and 4. Which sum occurred most often? 2 3 1 3 2 1

10
Leo and Sally use two spinners and record 10 differences: 2, 3, 5, 5, 2, 4, 3, 5, 4, 4. Show how they could make a table to find the differences landed on most often and least often. DifferencesNumber of Spins

11
Warm Up: Solve the following 1.) 2 x 9 = ____2.) 3 x 7 = _____ 3.) 6 x 4 = ____4.) 4 x 4 = _____ 5.) 3 x 8 = ____6.) 7 x 6 = _____ 7.) 8 x 6 = ____8.) 6 x 6 = _____ 9.) 8 x 8 = ____10.) 6 x 3 = _____

Collecting Data Information collected about people or things is called data. To gather the data you can survey people. The answers from the survey are called the results. You can record the results in a tally or frequency table. A tally table uses tally marks to record data. A frequency table uses numbers to record data. The students in Kellys class voted for their favorite dinosaur. The made a tally table and a frequency table to record the results. Lets look at examples of each. Push to see example of a tally table.

Favorite Dinosaur Tally Table NameTally ApatosaurusIIII I BrachiosaurusIIII II TyrannosaurusIIII IIII II StegosaurusIII

14
Favorite Dinosaur Frequency Table How many people were surveyed? Which dinosaur was the most popular? Which dinosaur was the least popular? How many votes did the Apatosaurus and Brachiosaurus get in all? List the dinosaurs in order from the most votes to the least votes. Name Number Apatosaurus6 Brachiosaurus7 Tyrannosaurus12 Stegosaurus3

Lets make a Tally Table! Survey the students in your class. Record the results in the tally table. Make sure to survey every student 1 time. SnackTally Popcorn Cookies Granola Bar Apples Pretzels Name:_________________ Favorite Snack

16
Lets make a Frequency Table! Look at your tally table. Record information in numbers on the frequency table. SnackNumber Popcorn Cookies Granola Bar Apples Pretzels Name:_________________ Favorite Snack 1.) How many students were surveyed in all?_______________________________ 2.) How many students choose cookies as their favorite snack?__________________ 3.) List the snacks in order from fewest votes to greatest votes. __________________________________ __________________________________ __________________________________ 4.) How many more students chose cookies than chose apples?____________
