The Purpose of Graphs

■ What is a graph?■ How are graphs helpful to us?

The Purpose of Graphs

■ Graphs help us organize data.■ Data is a collection of facts, normally in

number form.■ We often see data recorded in a table.

Picture Graphs■ Picture graphs

organize data using pictures.

■ Each picture represents a certain number.

Picture Graphs■ One of the most

important parts of a picture graph is the key. The key tells us what each picture represents.

Picture Graphs■ How many students

are in Mrs. L’s class?

Picture Graphs■ How many students

are in Ms. S’s class?

Picture Graphs■ How many more

students are in Mrs. L’s class than Ms. N’s class?

Picture Graphs■ How many fewer

students does Mrs. J have than Mrs. C?

Picture Graphs■ How many students

are there altogether?

Creating Picture Graphs■ Use this data to create a

picture graph:■ Daniah took a survey of

student’s favorite ice cream flavors. This table shows the data she collected.

Day 2: Bar Graphs

Problem of the Day

■ Mrs. Cinnamon has 5 boxes of cookies. Each box contains 12 cookies. She gave away 3 plates of cookies to her neighbors. Each plate had 15 cookies on it. How many cookies does Mrs. Cinnamon have left?

Bar Graphs

■ �Bar graphs represent data just like picture graphs. However, bar graphs use bars to represent a number instead of pictures.

Bar Graphs

Some bar graphs are horizontal and some are vertical.Which bar graph is vertical? Which is horizontal? Does the information change?

Bar Graphs

■ �Looking at the horizontal axis, how many fruits were used to graph the data?

Bar Graphs

■ �Which fruit is

liked the most?

■ Which

fruit is like the

least?

Bar Graphs

■ How do we read

the value of each

bar?

■ How many people

liked bananas

best?

Discuss as a Team

■ How many more people liked blueberries than oranges?

■ How many more people liked apples than kiwifruits?

■ How many people participated in this survey?

Day 3: Line Plots

Problem of the Day

◼ Malik bought 20 apples. Zollie had 3 times as many apples as Malik. How many apples did the 2 boys have altogether?

Key Vocabulary

Line Plot- A graph that displays data as points above a number line or some other line of characteristics or attributes.

Items to Review

*Show the students a ruler and make sure that they see the inches side. *Review how to measure an object using the inches side of the ruler.

Learning Activity #1: Line Plot Introduction

Watch the video below about line plots and collecting data for a line plot (pause at 3:19 to freeze the line plot). https://www.youtube.com/watch?v=mHCBtKFhV8M

Assessment for Learning Activity #1 (Print out these questions)● How many objects measured 3 inches?● Which 2 measurements had 1 object?● Which measurements had 0 objects?● Which measurement had the most objects? How many?● How many objects measured 4 inches?● How many total objects were measured?● How many more objects measured 4 inches than 3 inches?● HOT (Higher Order Thinking) ?-What if each “X” represented 3 objects?

*Discuss Previous Questions

Learning Activity 2: Creating a Line Plot

Create a line plot using the data from measuring different pens to the nearest half inch (pg. 49 in Common Core Worksheets for All Grade Standards)● Measure each pen to the nearest half inch using a ruler.● Make sure you write the measurement under each pen.● Make an “X” for each pen representing each of the measurements on

the line plot at the bottom of the page.

Assessment for Learning Activity #2

The line plot at the bottom of the pg. 49 in Common Core Worksheets for All Grade Level Standards.

Learning Activity #3: Group Created AssessmentsEveryone in the group needs to make sure that they have the same data plotted on the line plots.

Discuss the data on the line plot.

Create 5 questions as a group using the data from the line plot.

Assessment for Learning Activity #3

Swap questions with another group and answer their questions together (as a group).
