CONSTRUCTING BAR GRAPH
Grade 5 Math
ANALYZE LEARNERS
GENERAL CHARACTERISTICS The students for whom this lesson is intended are 5th Graders of St. John’s School, Guam, USA. They are average learners whose ages range from 10 to 11 years old. A few of them are identified as having learning disabilities, whereas others are considered advance in reading and mathematical skills. Generally, they are from good socio-economic families. The majority are Asian (Korean, Japanese, Chinese, Vietnamese, & Filipino) and the rest are Caucasian (American, Australian, Italian) and Pacific Islanders (Guamanian). For most of the time, these students are well behaved. However, they tend to lose attention and interest amidst long teacher monologue. They find hands-on activities and visual presentations engaging.
ENTRY COMPETENCIES The 5th grade science students are able to do the following:
• Understand the theme and objective of a reading selection.
• Observe and interpret charts and graphs.
• Comprehend definitions and categories
• Grasp relationships from parts to whole, from specifics to general
• Make conclusions from given facts, inductively or deductively
• Compute Mean, Median, and Mode
LEARNING STYLES Overall, these students are visual and kinesthetic learners. They understand and respond better to illustrations and to hands-on activities. They prefer group activities and group interaction. They have relatively satisfactory listening skills. They respond to pencil paper evaluation.
STATE OBJECTIVES
At the end of the lesson, the 5th Grade Science students will be able to:
1. collect responses and tally the frequencies.
2. construct these data using bar graph.
3. compute for the mean, median and mode of the collected data.
SELECT METHODS, MEDIA, AND MATERIALSSURVEY PAPER: The teacher needs to prepare a survey paper containing the questions that will solicit responses on how long do Grade 5 St. John students spent time studying Math at home.
FREQUENCY CHART: The teacher needs to print frequency charts to tally the student’s survey responses.
COMPUTER: The teacher needs to set up the computer that has the Excel program and open it ready for data entry taken from the frequency chart.
PRINTER: Computer Colored Printer is set up in order to create a hardcopy of the charts generated from the Excel Program that contain the data inputted by the students.
PENCIL & ERASER: The students have to provide these when they will collect the responses from their survey questionnaire.
UTILIZE MEDIA AND MATERIALSPREVIEW MATERIALS: The teacher will check the computer set-up in the classroom. The Excel Program should be in running condition to generate the chart and graph output from the students’ survey. The teacher will check if the Word Processing program is working in order to produce the Survey Questionnaire and the Frequency Table Chart. Lastly, the teacher will check the appropriate schedule for the Grade 5 students to survey each other.
PREPARE THE MATERIALS: The teacher will create the survey questionnaire and the frequency table chart needed for the activity. The computers should have the Excel programs running for data entry. The printer should have ink and papers necessary for the printing of the hardcopy of the Bar Graph and Chart. The teacher will prepare a Rubric for grading their Graphs, Table, and Computations.
PREPARE THE LEARNERS: The teacher will review the students on how to compute mean, median and mode. Furthermore, the teacher will explain the process on how to create a bar graph from the data provided in a frequency table using the Excel Program. The students will be divided into groups of 2.
PROVIDE THE LEARNING EXPERIENCE: The teacher will guide the students the process of generating graphs from the Excel program. The students will create a sample bar graph from a sample data.
REQUIRE LEARNER PARTICIPATIONLARGE GROUP ACTIVITY: The class will start with a quick review on how to compute mean, median and mode. Then, the class will discuss the importance of visually presenting the data collected from a survey and the purpose of bar graphs. The class will make a sample bar graph from the Excel program. The class will print these sample bar graphs on paper. The teacher then will discuss the survey activity and the content of the questionnaire. The students will also be guided on how to consolidate the data into the frequency chart. Lastly, the teacher will explain the rubric of how they will be graded in their graph, table and computation.
SMALL GROUP ACTIVITY: After introducing this activity, the students will go to their assigned groups. They will perform the survey and consolidate the data they collected into the frequency chart. They will input these data into the computer’s Excel program and generate the bar graph. After careful review, they will print these for their hardcopy. From the table, they will compute for the mean, median, and mode.
PRESENTATION: The groups will present to the class their respective graphs and central tendencies computation.
EVALUATE AND REVISEASSESSMENT OF LEARNER ACHIEVEMENT: The 5th Grade Science students will be graded according to the Rubric prepared for their Graphs, Table, and Computations.
EVALUATION OF MEDIA AND METHODS: To evaluate the effectives of Media and Methods, the teacher will make a Q&A session with the students after doing the presentation.
