• Click + Class/Group
• Click Class in the Group Type 
• Click Add Another to add more classes at one go as many times as the number of classes you want to create
• Enter the Class Names
• Select the Grades of each class you entered

All the classes will be added to your community and will start showing up under the classes/ groups tab of your community. Now you can invite respective teachers to these classes. They will be automatically added to the community as teachers when you invite them to the class.
