Part B: Fill in the Blank
Write the correct answer on each line.
1. Soccer and tennis together got 11 votes.
Soccer had 9 votes and tennis had 2 votes. Adding both: 9 plus 2 equals 11.
2. The sport that got exactly 5 votes is basketball.
Scanning the list, basketball is the only sport with a count of 5. Every other sport has a different number.
3. Soccer got 3 more votes than running.
Soccer had 9 votes and running had 6 votes. Subtract to compare: 9 minus 6 equals 3.
4. The title of a graph tells you what the graph is about.
The title sits at the top of a graph and names its topic, such as Favorite Sports. Without it, you would not know what the graph is counting.
5. If each picture on a pictograph means 3, then 4 pictures stand for 12.
Each of the 4 pictures stands for 3 items. Skip-counting by threes four times: 3, 6, 9, 12.
