Algebra started parallel/perpendicular lines today while geometry dove into exploring parallelograms.
It was fun to see students struggle in creating a parallelogram without any knowledge of their properties. There were a lot of methods used; I had to restrict students from creating rectangles/squares because they ALL jumped to that solution first.
After they created a parallelogram, they measured the sides/angles and taped them up to a whiteboard (I messed up in not asking them to spread them out further).
Students then gallery walked and filled out the table attached to the worksheet.
We talked about the properties and came up with a list hitting four big properties.
Tomorrow we will prove a couple of these and practice using them.
