We did not go into order of operations in class so I thought this gizmo would be great to refresh my memory of this topic. The gizmo randomly gives students a problem with various operations inside. When you hover over an addition, subtraction, multiplication, division, or exponent sign the gizmo will tell you what that sign will do. If you click on an operation that does not follow the order it will tell you so. Which is very good to enforce the order.
I really like this, though, I do think that it should display what the order of operations is in example problems then have the real round of problems. I would use this in my classroom, but I think it should be used at an intermediate level, just because the operations like exponents, parenthesis, and exponents outside the parenthesis can be very complicated for even sixth grade students.
