Lesson Plan of Reading Information in a Bar Graph
Students` Learning Outcomes
- Read to compare information given in a pie chart and a bar graph.
Information for Teachers
- Picture graph are used for comparison. We have different types of picture graphs which include histogram, bar graph, line graph, etc.
- Graphs and charts help us understand the data better.
Material / Resources
Writing board, chalk/marker, duster, textbook, picture graph at the end of lesson plan
- Show the students the picture card of the graph attached at the end.
- Ask the students to read aloud the information across the graph. (Expected answer would be as; comparisons between students of class four and class five).
- Ask the students to read the information down the graph, loudly. (Expected answer would be as; 100,90,80,70,60,50,40,30,20,10,0).
- Appreciate the students by saying very good for correct answer.
- Ask the following questions: as;
- What information does bar graph give? (Expected answer would be as; it gives comparison)
- Why do we read information on the bar graph? (Expected answer would be as; to get comparison).
- Draw the bar graph given at the end of the lesson plan, on the writing board.
- Ask the students to look at the graph pasted on the writing board and answer the following questions: as;Read the names of the fruits given in the graph. (Expected answer would be as; apples, bananas, oranges, mangoes).
- The classes are given colored codes. What color is allotted to each class? (Expected answer would be as; blue to class 4, red/maroon to class 5).
- What does the graph show? (Expected answer would be as; Comparison of percentages of grade four and five students who like bananas, apples, oranges and mangoes)
- Ask the students to discuss for five minutes, (in pairs) after looking at the graph, the percentage of students in grades four and five like the given fruits.
- Remind them the following points: as;
- The color code will give you the comparison between percentages of students of grade four and five who like the four fruits. All the blue bars represent students of grade four, while the red ones represent students of grade five.
- Ask the students, what percentage of students like to eat apples in class four and five? (Expected answer would be as; 10% students of class four and above 60% students of class five like to eat apples.)
- On giving correct answers ask the class to clap for the students.
- Ask students, what numbers are written on the extreme left side of the graph. (Expected answer would be as; 0,10,20,30,40,50,60,70,80,90, and 100)
- Ask them to look at the graph and tell the percentages in which students of grade four fall in eating bananas, oranges, mangoes (above 20,30 and 60).
- Guide them to look at the left side of the graph for the percentages given and the category they are falling in. also tell them that each gap i.e. 0-10 is covering 10 points, 10-20 again, is covering next 10 points each for reaching up to 100.
Sum up / Conclusion
- Ask the students to share their responses.
- Ask questions as to why a bar graph is used and what information we can get from it?
- Ask them to think of any other graph which they have seen in their everyday life (it can be any cricket graph).
- Ask them to write the following questions in their notebook and answer them. Which fruit is liked the most by grade four and five students? (Expected answer may be as; oranges are liked most by grade five students and mangoes by grade four.)
- Who likes to eat bananas more? (Expected answer may be as; Grade five`s students like to eat bananas more.)
- What percentage of children, in grade five, likes to eat bananas? (Expected answer may be as; above 70 percent of grade 5 children like to eat apples?)
- What percentage of children, in grade five, likes to eat apples? (Expected answer would be as; above 60 percent of grade 5 children like to eat apples.)
- Note- you can draw the picture graph on a card paper. Do not cut it from here. Information about the fruits liked by the children of class four and five(in the bar)
