Prime Number – a number that has no factors
5 7 13
Composite Number – a number that does have factors
9 12 2033 43 54

Multiples of 5: 5, 10, 15, 20, …
Even Number – any number that is a multiple of 2
8 6 12 200
Odd Number – a number that is not a multiple of 2
3 5 7 9
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.
