Lesson: Creating a Stem and Leaf Plot
Lesson Objective
Lesson Plan
Standard 

6DASP.1 – Describe and compare data sets using the concepts of median, mean, mode , maximum, and range. 

Aim/Objective:

Key Points


SWBAT create a stem and leaf plot. 
· Stem and leaf plots is a combination of a table and graph that displays numerical data · Stem and leaf plots are organized by tens – which are called “stems” · “Leaves” represent the ones digit of a number and should be matched to the ten “leaf” on the same line · Stem and leaf plots help to show the shape of the data 

Assessment:


1. Michael’s math quiz scores are shown below.
88, 87, 95, 72, 78, 80, 83, 80
Which of the following is a stemandleaf plot that correctly shows Michael’s math scores?




Warm Up: (5 mins)
·
Opening (5 mins)
· Show students different samples of displays for graphs from a newspaper. · ThinkPairShare: Ask students why they think people use graphs to display data? Do you think that certain graphs are better for certain types of data?
Intro/Direct Instruction (10 mins)
· Today we are going to learn about a certain type of graph called a stem and leaf plot. · Stem and leaf plots are a way to display numerical data in order. · It’s called a stem and leaf because it has stems and leafs (stems are digits to the left of line/leafs are digits to the right of the line) guide · Model two examples of creating stem and leaf plots using data. · Enforce that students include a key with their work. o Step 1 identify the min and max; o step 2 – arrange the numbers in order from least to greatest o step 3 – write the stems using the data arranged in order o step 4  write the leafs in numerical order o step 5 – create the key (____ represents ____) and title Guided Practice (10 mins)
· Students will work in small groups to create a stem and leaf plot · Teacher will guide students through the process – asking appropriate questions to the whole group and students will create the stem and leaf plot, one part at a time. o What is the first thing we need to do? (identify the minimum and maximum) o What should we do next? (order the data) o Who can tell me the next step? (write the stems) o Now that we have the stems, what should we do next? (write the leaves for each stem) o In order to make sure that people who read our graphs know what it’s about, we need to remember to….(write the title, make a key) Independent Practice (15mins)
· Students complete worksheet – teacher circulates to monitor understanding/practice – or pull a small group of students who struggled during the guided practice
Closing (5 mins) · Review Key Points for the students. · Ask students to “turn and talk” to classmates on what the steps are to creating a stem and leaf plot · Give Exit Ticket for students to complete.
