1. ACTIVITY 2: MAKING TABLE, GRAPHS, AND CHARTS USING WEB-BASED APPLICATIONS DISCUSSANTS: ENCARNADO SILMARO

2. LESSON PLAN IN MATHEMATICS 7 Content Standard: The learner demonstrates understanding of key concepts, uses and importance of Statistics, data collection/gathering and the different forms of data representation, measures of central tendency, measures of variability, and probability. Performance Standard: The learner is able to collect and organize data systematically and compute accurately measures of central tendency and variability and apply these appropriately in data analysis and interpretation in different fields. Learning Competency: The learner uses appropriate graphs to represent organized data: pie chart, bar graph, line graph, histogram, and ogive. M7SP-IVd-e-1

3. OBJECTIVES: At the end of the lesson, the students can be able to: a.Differentiate the different graphs used to represent organized data. b.Use appropriate graphs to represent a given organized data: pie chart, bar graph, line graph, histogram, and ogive. c.Value the gift of nature around us . SUBJECT MATTER Content : Graphs to represent organized data

4. T o test your ability, answer the problem with the given data. 1) Compute the percentage. 2) Draw a pie graph.   PROCEDURES: ACTIVITY

8. A pie chart is a type of graph representing data in a circular form, with each slice of the circle representing a fraction or proportionate part of the whole. All slices of the pie add up to make the whole equaling 100 percent and 360 degrees. A line graph , also known as a line chart or a line plot, is commonly drawn to show information that changes over time. You can plot it by using several points linked by straight lines. It comprises two axes called the “x-axis” and the “y-axis“. The horizontal axis is called the x-axis. • Reference/s: Teacher’s Guide (TG) in Math 7, pp. 50-60
