Exploring Stem-and-Leaf Plots in Grade 5 Math

In this video tutorial, Miss Granados introduces the concept of stem and leaf plots, a method for representing data. The lesson begins with an overview of learning objectives, including correctly inputting stems and leaves, titling the plot, and including a key. The video guides students through the process of creating a stem and leaf plot, using examples such as fat grams in food items and temperatures in Mérida, Mexico. Students are encouraged to notice and wonder about the data, analyze it, and reflect on their understanding. The tutorial concludes with a reflection on the learning objectives and a preview of future lessons on data interpretation.

What materials are needed to create a stem-and-leaf plot by hand?

• None of the above

• Calculator and graph paper

• Paper, writing tool, and a ruler

• Laptop and spreadsheet software

What is the primary purpose of a stem-and-leaf plot?

• To calculate complex equations

• To solve algebraic expressions

• To display frequency of data using whole numbers

• To graph functions

What is the first step in creating a stem-and-leaf plot?

• Drawing the plot lines

• Sorting the data

• Identifying the data set

• Labeling the stems and leaves

How should data be arranged before placing it into a stem-and-leaf plot?

• From least to greatest

• Does not need to be arranged

• Randomly

• From greatest to least

What should you do if a number repeats in your data set when creating a stem-and-leaf plot?

• Increase the stem count

• Ignore the repetitions

• List it as many times as it appears

• List it only once

Why is it important to include every piece of data in a stem-and-leaf plot?

• To make it complex

• To use up space

• To ensure accuracy

• To make the plot look full

In a stem-and-leaf plot, what does the 'leaf' represent?

• The highest value in the data set

• The total count of data points

• Digits in the ones place

• Digits in the tens place

How are the stems determined in a stem-and-leaf plot?

• By the hundreds digits

• By the ones digits

• By the data frequency

• By the tens digits

What does the key in a stem-and-leaf plot explain?

• The range of data

• The meaning of the numbers in the plot

• The title of the plot

• The frequency of the data points

What does a complete stem-and-leaf plot include?

• Numbers and labels

• Numbers, a title, and a key

• Numbers and a title

• Only numbers
