There are 26 third graders and 32 fourth graders going on a field trip. each van can carry 10 people

Approximately 6 buses

Step-by-step explanation:

If you are wanting know how many vans they are going to need:

26 + 32                    -This helps you know how many total kids there are

= 58

58 / 10                      -This solves how many buses you'll need

= 5.8                   - Round up, and say you need 6 buses.
