Wednesday, April 8th

Today’s lesson focused on calculating the area of parallelograms. Our classroom discussion centered around determining which side of the parallelogram is the base. This was my instruction to students:

“The base side is the side of the figure that the height line intersects and forms a right angle.”

I also reminded students that opposite sides are equal. Many of tonight’s problems only give measurements for two sides of the figure. I have taught my students to look to the opposite side of the figure if they are missing a measurement. Again, opposite sides are equal.

Please remember: calculate both area and perimeter for tonight’s homework.
