This article walks through the cause and possible steps to take to resolve the Large Classroom warning.
What Does This Warning Mean?
|
Large Classroom: You are about to create a classroom with more than X students. If you didn’t intend to do this, please ensure you’ve added enough unique classrooms to the file. Learn More. Large Classroom Names: First Grade Math, Second Grade Math Rows: 1-68; 67-150 |
If you see the Large Classroom warning after uploading your spreadsheet, it means that 50 or more students on the spreadsheet are associated with the same DreamBox Math Classroom name (Column G). You are creating one or more classrooms that have 50 or more students in them. We recommend that students be grouped into classrooms of 49 or fewer students.
Why Is This Happening?
You may not have intended to create classrooms that are this large. The most common reason this happens unintentionally is that all classes in a grade level have the exact classroom name. The system thinks you want to put all students in that grade level into the same classroom, vs separate classes with different teachers.

Large Classroom: You are about to create a classroom with more than X students. If you didn’t intend to do this, please ensure you’ve added enough unique classrooms to the file. Learn More. Large Classroom Names: First Grade Math, Second Grade Math Rows: 1-68; 67-150 |
In the example warning above, the spreadsheet triggered a warning because:
- All first-grade students were grouped into one large First Grade Math classroom
- All second-grade students have been grouped into one large Second Grade Math classroom.
Resolving the Large Classroom Warning
To resolve this warning, review the classroom names and teacher emails in the rows specified in the warning. Look for:
- Two or more teacher emails associated with the same classroom name.
- Review these rows and determine:
- If you intended to add multiple teachers to the classroom and the classroom is 49 students or less, leave the spreadsheet as-is.
- If you see the students for two or more separate classrooms associated with the same classroom, update the classroom name for each group of students. The easiest way to do this is to add the teacher's last name to the classroom name.
Example Resolution
In the example warning, the first grade students from three different classes had been grouped into one giant classroom because the classroom name was the same: "1st Grade Math"
To address the warning, the administrator could make every classroom name unique by adding the teacher's name to "1st Grade Math".
