Keywords: 6th grade math, Math, powerpoints, Statistics, visual math

School Subject(s): Math, Statistics

This unit assist teachers in the development and understanding of statistics. Students will focus on understanding the uses of statistical questions and their connection to data use in math moving towards the best measure of center and measure of variation for a set of data. There are four interactive sessions between the teacher and the student. Session 1 involves the application and conceptual understanding of the mean. Session 2 involves the application and conceptual understanding of Mode and Median. Session 3 involves the application and conceptual understanding of the Best Measure of Center. Session 4 involves the application and conceptual understanding of measure variation. Sessions 4 is a cumulation of lessons 1-4, which illustrate the mode, median, mean, range, outlier, gap, cluster, measures of center and measure of variation. The last lesson moves to find the interquartile range while illustrating the median for the set of data, branching off to the median for the first quartile and the third quartile. The teacher will explore the PowerPoint with students in flexible group to practice the application and conception of skill of using data to decide how to best represent the center and the measure of variation in a set of data.

Problem Statement:

Teaching student Statistics in grade 6 has proven to be a challenge as my students have demonstrated the difficulty of understanding the importance of statistics in their daily lives and the true purpose of statistics. I have learned that my students have a difficult time understanding what is or not a statistical question, how to read data (charts and graphs), or even how to interpret their meaning and purpose. The students that I serve are an at-risk student population within Philadelphia. Many of my students are first-generation immigrants from war-torn countries or have been impacted by adverse experiences in their crime-ridden and low-income neighborhoods. In their case, statistic serves no purpose in their lives. Therefore, it is difficult teaching them the application and conceptual knowledge to understand and interpret statistics.

 

Despite such a long history of educators and parents striving to provide the best possible setting and services to children in the Philadelphia area. Educators are facing new and significant challenges that require them to use various approaches to educate their current student body. The at-risk student population I serve, consists of over 95% of the population who are economically disadvantaged; 100% of the study body qualifies for free lunch; about 20% of the student body is enrolled in special education. Also, it has a rivaling population between the African descent student population and the African American student population, which was resolved through professional development and preventive measures by the district. The challenge of being in a high-crime (often considered as having the highest crime rate in the Philadelphia County) and low socioeconomic community. Most importantly, many of my students come from adverse childhood experiences (poverty, neglect, abuse, and worn-torn countries), which has greatly impacted their academic performance at the school. It is difficult to get them to understand and interpret statistics, which will be used in their academic journey and their daily lives.

 

The general problem is teachers in urban areas teach at-risk children (low-income, poor health, and poor attendance), and various ethnic backgrounds, which tends to hamper their academic performance. Teachers in this setting must tailor lessons with pedagogical concepts and strategies, which best fit the needs of their students to ensure engagement in the classroom (Edmonds, & Li, 2005; Means, Toyama, Murphy, & Baki, 2013). Teachers are also encountering challenges of engaging diverse groups of students in a blended learning classroom and regular classroom  (Balfanz, Herzog, & Mac Iver, 2007; Riel, Lawless, & Brown, 2016). Middle and high school students in an urban setting tend to misbehave, not attend school regularly, and not be engaged in their academic assignments (Balfanz, Herzog, & Mac Iver, 2007; Riel, Lawless, & Brown, 2016). I believe an interactive way of teaching statistics such as visualization and comic may engage them in wanting to understand and interpret statistics or mathematics.

 

The specific problem is teachers instructing at-risk children (low-income, poor academic performance, various languages and various ethnic backgrounds) use pedagogical concepts that best fit their students’ needs to ensure engagement occurs in the classroom (Edmonds & Li, 2005; Means, Toymana, Murphy & Baki, 2013). Students are not performing well in math due to the gaps in skills. A student may not have grade-level skills or backgrounds to perform well in their current grade. Students require a process or best practices, which can close the gap in their learning such as interactive lessons.

 

“A Visual Approach to Learning Math” seminar has sparked the development of ideas on the topic of mathematical visualization for sixth-grade statistics within me. I coming to realize that the visualization of teaching statistics can be instrumental when instructing students in the classroom. For instance, I have prepared four interactive presentations that will use number lines, letters, or objects to illustrate averages, clusters, peaks, and outliers that students while being manipulated to perform the required task to engage students in a lesson.

 

The use of visualization by the usage of technology and best practices in a math unit for the purpose to improve teaching and learning in the classroom critical to enhance the engagement of students in the classroom. This math unit will encourage teachers to be creative as they take away from the unit and may cause them to develop their way to illustrate and animate mathematics at a variety of levels. This unit will explore how teachers can evaluate complex problems in an animated medium where students can explore their ideas, thoughts, and questions generated from the exploration of statistics. The understanding of statistics will assist students in their interpretation of the world (Walle, Karp & Bay-Williams, 2019). The unit will guide instruction for students to reach their academic potential in the classroom, which allows them to meet the common core standards. This unit will be linked to a mathematical application while addressing the conceptual knowledge of math for the student. This unit will aid in the increase of appreciation for statistics, may increase academic performance on state assessments, and for teachers to develop a fun and engaging approach to the math in their classroom.

 

Session 1 involves the application and conceptual understanding of the mean.  This portion of the unit on statistics begins with the understanding of whether a question is statistical on nonstatistical while leading to formulating statistical questions. Then, the lesson involves the understanding of the meanwhile leading to calculating a data set to derive at mean. Citizens will have to address questions that are statistical or nonstatistical in their daily lives, which provides the necessary reason to teach this concept to children that are exposed to these types of questions in their math class and daily lives.  The use of visualization allows the student to engage in the lesson and visibly see the concept being taught in class.

 

Session 2 involves the application and conceptual understanding of Mode and Median of a set of data. The lesson illustrates the mode is number in the data that occurs the most. The visual presentation allows students to conceptualize the mode of a set of data. The lesson moves to understand the median as the middle number.  The visual presentation allows students to visualize the median in a set of data. Also, the teacher discusses mode, median, and mean of a set of data. The mode and median are not affected by the data as the mean  (Walle, Jarp & Bay-Williams, 2019).

 

Session 3 involves the application and conceptual understanding of the Best Measure of Center.  The lesson illustrates the mode, median, mean, range, outlier, gap, and cluster in a set of data. The visual presentation allows students to conceptualize the mode, median, mean, range, outlier, gap, and cluster in a set of data through an interactive lesson in PowerPoint. The teacher will show students within flexible groupings that it is important to consider the context and data to decide how to best represent the center (Walle, Jarp & Bay-Williams, 2019).

 

Session 4 involves the application and conceptual understanding of measure variation. The lesson illustrates the mode, median, mean, range, outlier, gap, and cluster in a set of data. Then, the lesson moves to find the interquartile range while illustrating the median for the set of data, branching off to the median for the first quartile and the third quartile.  The students are shown how to determine the range of the first quartile from the thirds quartile to get the interquartile range. The visual presentation allows students to conceptualize the mode, median, mean, range, outlier, gap, cluster, and process to get the interquartile range in a set of data through an interactive lesson in PowerPoint. The teacher will show students within flexible groupings that it is important to consider the context and data to decide how to best represent the center and the measure of variation in a set of data.

 

Teachers can create a free google classroom for the use in the classroom. Google is a learning management system. The teachers can allow their students join their classroom for free using the code generated by google. Google classroom allows teacher to upload assignments for their students to complete.  The teacher can grade their students work in google and it provides a spread sheet of the graded work. Teachers can use google to load presentations for their students to review in the classroom or at the student’s home. Teachers can add power point presentations to their google classroom. This site is compatible with all components of google applications ( drive, docs, slides, forms, sheets and meets etc.). Teachers can create a google classroom by viewing this YouTube video titled, “The New Google Classroom – Full Tutorial” or click the link in the parenthesis (https://www.youtube.com/watch?v=M6L-nZGIUTE)

 

Teachers can adapt the slides presentations associated with this unit to accommodate their student learning. Teachers can upload their PowerPoint presentation to google slides to to incorporated into google classroom (https://www.youtube.com/watch?v=yN4QfhY72OA or https://www.youtube.com/watch?v=cBvxnYsiykY).  The slides with will assessible as long as they have access to their google drive or google classroom.

Motivational Moment: Play

 

https://www.youtube.com/watch?v=mWZ6b_I-Djg

 

The teacher will play a motivational video before the start of the formal lesson to inspire their students to work together.  The teacher will explain that each individual solves a problem in a way the answer suits them.  There may come a time a person will solve a problem in a way it will benefit the mass. Many of our assignments may involve individual work, small group and large groups to complete a task, but together will reach the common goal or outcome.

 

Materials:

  • PowerPoint Presentation
  • Smartboard or Projector
  • Pencil and notebook
  • DOL: Worksheet
  • Calculator

 

Teachers inform students standards should go into their notebook to review while teaching the lesson.

 

Standards

  • SP.A.2 Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.

 

  • SP.A.3 Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

(Miles & Williams, 2016).

Teachers inform students standards should go into their notebook to review while teaching the lesson.

Interpretation (What do students need to know and be able to do?) of standard for this lesson plan:

  • Perform a statistical investigation, including the collection, organization, and analysis of the data.
  • Analysis should include the appropriate statistics from mean, median, interquartile range, a measure of center, measure of variation, quartiles, lower quartiles, and upper quartile.

(Miles & Williams, 2016).

Objective:

  • Student will be able to understand that data generated from statistical questions vary IOT understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
  • The student will be able to recognize the responses to statistical questions have variations that can be to conclude the data set to recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

 

Teachers inform students standards should go into their notebook to review while teaching the lesson.

 

Essential Questions:

  • What is the best measure of the center of a data set?
  • How would you use a measure of variation to describe a data set?

 

Vocabulary:

 

Student will copy the vocabulary and their definitions into their notebook

Ø  Cluster is when the data is group together.

Ø  Gap is when there is a separation between a group of data and another data point.

Ø  Peak is the highest point in a set of data.

Ø  Means is the value obtained by dividing the sum of several quantities by the number; an average

Ø  Median is the middle number of a data set.

Ø  Measure of Variation is used to describe the distribution of a set of data

  • Mode is the number the appears the most in a data set or graph. There can be more than one mode.
  • Outlier is data that lies outside of the main group of data.
  • Range is the difference between the highest and lowest data points.
  • Interquartile range is the range of the middle half of the data and is another measure of variation.
  • Quartiles of a data set divide the data into four equal parts

 

Activity/Task

Students will be provided 5 minutes to complete independently. Students in their flexible groups will respond to the questions below.

 

Warm-Up

Activity 1

What is the interquartile range for the data?

60     80        85      90      95     100     105      110    115    120     125

 

Students in their flexible groups and the teacher will work together to locate the median.

 

 

Median

60     80        85      90      95      (100)     105      110    115    120     125

 

 

Students in their flexible groups and the teacher will work together to locate the median for the lower half and upper half.

Lower Half                                             Upper Half

 

 

 

60     80      ( 85)      90      95      100   105      110    (115)   120     125

 

The median of the lower half                    The median of the upper half

Is the first quartile, Q1                                   Is the third quartile, Q3

Q1 = 85                                                             Q3 = 115

Students in their flexible groups and the teacher will subtract quartile 1 from quartile 3

Solution:

Interquartile range (IQR) = Q3      –  Q 1

IQR  = 115     –  85

IQR  =  30

Activity 2:

What is the interquartile range for the data?

Group Assignment

CCSS.MATH.CONTENT.6.SP.A.1 Recognize a statistical question as one that anticipates the data related to the question and accounts for it in the answers. For example, “How old and/” is not a statistical question, but “how old are the students in my school? It is a statistical question because one anticipates variability in students’ age.

CCSS.MATH.CONTENT.6.SP.A.2 Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.

CCSS.MATH.CONTENT.6.SP.A.3 Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

CCSS.MATH.CONTENT.6.SP.B.4 Display numerical data in plots on a number line, including dot plots, histograms, and box plots.

CCSS.MATH.CONTENT.6.SP.B.5 Summarize numerical data sets concerning their context, such as by: a. Reporting the number of observations. b. Describing the nature of the attribute under investigation, including how it was measured and its units of measurement. c. Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern regarding the context in which the data were gathered. d. Relating the choice of measures of center and variability to the shape of the data distribution and the context in which the data were gathered.
