Vocabulary

Ordered Pair – tells how to find a point on a grid

(3,7)X - OVER

Y - UP

3. Find the ordered pair (1, 4):

4. Where is the ship?

5. What letter is at (6, 6)?

7. Where is R?

6. What letter is at (2, 3)?

Scale – where the numbers start and end on a graph axis

1512

9630

Interval – how much we count by in our scale

1512

9630

Circle Graph – a way to show data using slices of a whole circle

Circle GraphsThis week, we will recognize and correctly read a circle graph

Circle Graphs Should Have:

Title Key LabelsData Slices

Draw the graph. Circle and label each part of the graph.

1. What is this graph showing us?

2. Which food is most popular?

3. Which food is least popular?

4. What percent students liked Pecan Pie?

5. What percent of students liked Cherry Pie?

6. How much more popular was Apple Pie than Coconut Cream Pie?7. What percent voted for Cherry Pie or Pumpkin Pie?

8. State two facts from the graph.

Create a Circle Graph

We will collect and graph class data in a circle graph.

First, let’s collect data – raise your hand for your favorite type of food:

› Italian› American› Mexican› Asian

Create a Circle Graph

Using this data, let’s design a circle graph

Start with the title: Draw a circle where the graph will be

drawn in. Now, cut the circle into pieces

according to how many people voted for each food compared to the whole class (36 people).

Create a Circle Graph

Pictograph – a way to show data using a group of pictures

PictographsThis week, we will recognize and correctly read a pictograph

Every Pictograph Should Have:

TitleLabels*KeyData Pictures

Draw the graph. Circle and label each part of the graph.

1. What is the graph telling us?

2. What sport was most popular?3. How many students voted for it?

4. What sport was least popular?5. How many students voted for it?

6. How many more students voted for soccer than football?

7. State two facts from the pictograph.

8. What does the key show?9. The store has the most of which kind?

10. How many Golden Delicious apples?11. How many Red Rome apples?

Create a Pictograph

We will collect and graph class data in a pictograph.

First, let’s collect data – raise your hand for your favorite sport:› Soccer› Baseball› Basketball› Football› Other/None

Create a Pictograph

Using this data, let’s design a pictograph Start with the title: Now write a key where each ball = 2

students Draw a box where the graph will be

made. Label the left side with the sports. Now, draw a picture for each sport.

Remember, you may need to use half a picture to represent numbers.
