CREATING BAR GRAPH
GRADE LEVEL: 7
MATERIALS: Pen, paper, pencil, chalkboard, information sheets about Cocowalk, hand calculator
MATHEMATICAL CONCEPTS:The student, after an explanation and demonstration will be able to compare how many different places there at Cocowalk.
INSTRUCTIONAL OBJECTIVES: Bar graph, Vertical axis, Horizontal axis, Numerical scale
NCTM STANDARD: Standard 1: Mathematics As Problem Solving, Standard 2: Mathematics As Communication, Standard 5: Number And Number Relationship, Standard 8: Patterns And Functions
PROCEDURES:
a. Field trip to Cocowalk.
b. Teacher will collect all the information from brochures given at
the information booth. Information will show the number of restaurants,
cafes and theaters.
c. Name the bar graph as " Different places to visit
while at Cocowalk."
d. Label the vertical axis from the base to the top of graph
as "Number of Stores"
e. Label the horizontal axis from left to right as "Different
places to visit". BR>
f. Use bars of equal width.
g. Use equal spaces between each bars.
h. Use the data collected about Cocowalk and create a bar graph.
i. Have student work in small groups of 3-4 students
j. Make a tally table that shows the number of stores, cafes,
heaters, restaurants and the frequency.
k. The teacher will show the students how to use this information to
to create the bar graph.
l. The teacher will let students know that they can create different
kinds of graphs , for example, a histogram.
Bar Graph: A bar graph is used to compare categorical data and they do not touch each other.
ASSESSMENTS:
Teacher observation and demonstration. Check students
bar graphs for accuracy and completeness. See attached sheets for the
information to be used for the bar graph.
