Answers
1. The first bar lines up to 9.
The aquarium has 9 of which animal?
| Animal | Number at the aquarim |
|---|---|
| Otters | 9 |
The aquarium has 9 otters. So, the first bar should be labeled Otters.
Now let's label the other bars.
2. The scale counts up by 6s.
James spent 36 minutes completing his ocean project. We can find James at the bottom of the graph and create a bar over his name that is even with 36.
Now, let's do the same thing for the other 4 students.
3. This graph shows the most reasonable scale for the table:
4. There are 56 mastiffs. So, the first bar should be labeled Mastiff.
5. The scale counts up by 5s.
There were 15 students absent in 1st grade. We can find 1st grade at the bottom of the graph, and create a bar over it that is even with 15.
Now, let's do the same thing for the other 4 grades.
6. (b)
7. Apple had 55 votes. So, the first bar should be labeled Apple.
Now let's label the other bars.
