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.

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.

Mini-Golf Project

Today we started our next math project focusing on geometry in the real world! Here is the introduction video.



We will be working on this project for the next month.  I plan on using Google Sketch Up for our 3-D digital design. We will have lots of time in class to practice using this software.  Students can also play with it at home - it's a free download!  I can't wait to see your students' creativity!

GoNoodle Update and Current Events

Our final presentation for our GoNoodle projects will be this Wednesday in the learning lab at 10:30.  We will watch each video with a quick introduction by each group about their video.  I am so excited to share this project with all of you!

I also wanted to make sure that everyone has access to the current events rubric that I shared with the students today. I've also included the example I shared with the students today.  The first assignment is due the Tuesday we come back from the long weekend.
