Daily Math Review (WarmUp/ Do Now)

Find the median of each set of data: 1. 24, 42, 51, 25, 63 2. 38, 30, 26, 20, 32, 48, 3. 2.1, 3.2, 4.8, 5.6, 3.1, 2.6 4. 110, 120, 130, 125

Math Vocabulary

StemandLeaf plot: a graph that uses the digits of each number to show the shape of the data. Stem: digit or digits on the left Leaf: digit or digits on the right Key: Explain what your stem and leaves represent 

10 minutes 
Explore (Conceptual Development)

Use the table to draw a stemandleaf plot Table will be on guided notes: Discuss the steps to creating the step and leaf plot try to have students formulate these steps on their own as you create the stem and leaf plot together Steps: Step 1: Circle the stem: the number in the highest place value Step 2: Place the stems on a vertical line in numerical order and draw a vertical line next to the right of the stems Step 3: underline the leaves and place them next to the appropriate stem Step 4: Order the leaves from least to greatest

Students are creating the stemandleaf plot while synthesizing the steps to do so.

Explain
(Guided Practice)

Do one more examples with the students and have one that includes numbers with more than two digits. Determine what information we can gather from a stemandleaf plot (on stemandleaf GN worksheet) Do on last example with the students to analyze data using stemandleaf plots. Can we find mean, median, mode, range, max, and min? Is it easier to find any of these using a stem and leaf plot. Have them complete 3 stemandleaf plots with analyzing data on their own (given on worksheet) and do thumbs up or down for understanding. Teacher say: you will have 3 minutes to complete the first problem on analyzing data using a stemandleaf plot. Once you are finished please remain silent to let your colleges finish their work in silence. Once the 3 minutes ask for a volunteer to give the answer have other students give thumbs up or down for understanding then move on. Repeat this for each of the 3 questions. (those students that had thumbs down should be addressed during the next questions independent work time) 

15 minutes 
Extend (Independent Practice)

female students must write a two digit number from 5099 and the male students will write a three digit number from 100130 on a post it note. Once you have completed this tear your paper in the appropriate place (where the stem ends and the leaf begins. Have the students come up and place their leaf next to the appropriate stem. If they do not place them in numerical order on their own wait until they are finished and ask if we are finished (expect that somebody will say they are not in numerical order) Then analyze the class data with specific questions outlined in the stemandleaf guided notes

Homework

Analyze data using a Stemandleaf worksheet 

Lesson

For students that are struggling give them different color for each stem: IE any number that was in the 20’s would be red in the 30’s would be blue and in the 40’s would be green. Then have them attempt to create a stemandleaf plot
