Grade 3: Classroom Video

What does an Investigations classroom look and sound like? The videos below provide images of teachers and students at work in a range of third grade classrooms.

The teacher talks with a student about his representation of 27 divided into 9 groups.

One student explains how she added up to solve a story problem about the difference between the height of two people: 82-68.

Students discuss how many hundreds there will be if they add 709 and 546.

Students discuss ways they might use their "plus/minus rule" to add 623 + 249.
