Comparing
Can you remember what a Venn Diagram is? (We saw one in a previous lesson.)
Look at this example of a Venn Diagram. Talk about what it shows.

Look again and answer these questions:
- How many things are being compared?
- What do the three circles show?
- What does the part in the middle show?
- What are the three things being compared?
- What do they all have in common?
The same or different?
Now check the answers below. Did you have the same answers?
How many things are being compared?
What do the three circles show?
What do the parts between two circles show? (example: yellow)
What does the part in the middle show?
What are the three things being compared?
What do they all have in common?
Now you try it
Think about what you know about the three precaution signs from above. Can you fill out this Venn Diagram?
What do they have in common with each other? What do they all have in common?
