Visit and Record

Students participated in a math activity called visit and record. First students picked a 2 or 3 digit number. Then they made their number using base 10 blocks. On a slip of paper they wrote their name on one side and their number in standard and expanded form on the other side. Afterwards, students walked around the class recording other students' numbers and seeing if they agreed with how the student wrote their number in expanded form. If they disagreed, they found that student and tried to work on the expanded form for that number together.
