Ratio, Proportions, and Similar Polygons

Christmas break is officially over! We are starting off the semester with similar polygons and these interactive notebook pages will be our notes for our first week back....

We will start tomorrow by reviewing ratios and proportions.




For practice, I will be assigning students the partner activity that can be found on my classroom activities page: http://newellssecondarymath.blogspot.com/p/classroom-activities.html. The partner activity that students will be completing will be done independently but together (if that makes sense). Partners will complete separate columns but will both receive the same answer. 

The next day, we will go over the similar polygons flip-book that I have used for the past 2 years. This year, I decided to create activities that go in between the flaps. I created a scale factor card sort that students will complete once we finish the scale factor section. I also created a maze review activity over corresponding sides and angles once we are finished with the whole book. In previous years, we completed the whole book all at once and it was overwhelming so we will see how this year goes!







We will take a quiz on Friday (that can be found here) so I can assess whether we need more practice over solving proportions since similar polygons is heavily based on correctly setting up and solving proportions. If my students are struggling, then we will forget the pacing guide and complete some more practice!

Here are the foldables that I will be using this week:

  1. Hi there,

    Your resources are amazing! Thank you for all of your hard work! By the way, your link to the Ratios and Proportions classroom activity does not work.

  3. Are the ratios and proportions guided practice and the 'green' similar polygon page available to download? I like what you have. Thanks for sharing!

  4. Question: On the last foldable on Corresponding Sides, you set two corresponding sides equal to each other. Shouldn't they be in a proportion? (9/2 = y+2/5)

    1. I have the same question as well. I believe they should, so I am adjusting my notes. Unfortunately I did not catch this until 3rd period. =(
