We cover the following content today:

* Area of a Parallelogram: A = base * perpendicular height

* Area of a Trapezoid: A = (a + b)h/2 where a and b are the lengths of two parallel sides and h is the keight

* Perimeters and areas of composite plane figures

The key takeaway points are to remember those formula for perimeters and areas of various figures. Composite figures are made of those special figures.

We first went over the midterm exam questions. Some students didn’t do very well. I have emailed every parent about the student’s exam result. Parents, please ask to see the student exam paper and talk to your kids.

Do encourage your kids to ask questions in the classroom if there is anything he/she does not understand.

We studied perimeters and areas of a square, a rectangle, and a triangle, and we studied the circumference and area of a circle.
