For these problem types we deal almost exclusively rectangles so the formulas are easy. They are not given all the sides usually, but instead given either the length or the width and then the perimeter or the area and asked to find the missing piece. For rectangles as long as they have one side they can figure out the other for both area and perimeter. I've noticed that the students gets confused as to when to use which formula. I've made some notes that I am hoping will clear some things up and provide a place to go back and review. If you have questions, or your child needs more practice, please let me know.

Area and Perimeter
Area and perimeter are seeming to be difficult to decipher for my students this year. We've seen area and perimeter questions on Math 4 Today since November but we still need more practice. I sent home area/perimeter homework on Monday and you will see more come home today. We did some error analysis today in class to go over the common mistakes I saw on Monday's homework.
