WMS: Wednesday's Math Play-by-Play

Dear Families,

This is today's play-by-play for math so that everyone can be on the same page as semester 2 starts. More information is available on my website (http://www.mrmacnevin.com) regarding how I'm using Zangle differently this semester to provide better information to parents.

Cheers,

Our math To-Do-List today:

• MR Feedback: Students used the math review answers to evaluate their math review from last night. They mark correct answers with a star and they mark incorrect ones with an "H" so they know to revisit it at homework time. Anything marked with an "H" should also have the correct answer and a strategy recorded so that they can practice that calculation at home.
• Homework Check-in: As students corrected their Math Reviews and recorded feedback, I went around to look at homework. If they completed last night's homework, I stamped today's  date (the homework's due date) in their planner. If today's date in their planner is not stamped, they did not have their homework complete or they did not have it out for me to stamp.
• Learning Targets 3 & 4 Quiz: Student took the quiz and read if they finished early. Then we took a little time to go over the answers that had absolute answers. I still have the quizzes as I need to grade the items that include approximations or problem solving.
• New Topic: Student took some notes about how circles compare to polygons when talking about perimeter (circumference) and area. Then we measured the diameter and circumference of several objects in the classroom to discover how many times the diameter would fit around the outside of the circular object (about 3.15 to 3.25 were common measures). We then talked about how people doing this with REALLY precise instruments find that it's about 3.14 diameters and many students recognized that as the approximation of pi. Then we talked about how you don't have to measure the circumference directly if you know the diameter of a circle... that you can just multiply the diameter about 3.14 times to find the circumference (C= pi x diameter).
• Homework Assignment:
• MR 2C (Math Review 2C due 2/23)
• Circumference Wksht (due 2/23)
• Students have a pizzazz math page to practice calculating the circumference of a circle based on the diameter or the radius of a circle. The should definitely use the formula C= pi x d. And when just the radius is given, they have to double it first to find the diameter.
