What is that? How do you use it? #blaugust

Side note, this blog post is in no way a criticism of anyone or school or anything along those lines.  It is just what happened in class today.  If anything, it might be a criticism of myself as while I was planning this lesson, I assumed my students’ experience would be greater with this tool.

Today was the second day of real “content” with my Geometry students.  After years of the Common Core Standards in place, which I know includes Geometry standards at the 7th grade level, I am still amazed when students remark that they have not used a protractor before, and I am fairly positive that they are being truthful (or at least that they didn’t remember actually using one).

What was intended to be a five minute “review” of these skills to launch into the real lesson activity of the day turned into a much more in depth “teaching” of how to use this tool.  Although they might NEVER use a protractor outside of my class again I do find the task of measuring something using a tool useful. The task also spoke to the CCSS Math Practice Standards of attending to precision and using tools strategically. It is so challenging (especially at the beginning of the year) to determine what are appropriate scaffolds to help students work on a task. Moving forward, I plan to assume less which is actually a good thing because then we can talk about refined meanings of things.  For instance, because of their lack of background we were able to really talk about that the measurement in degrees was actually a measurement of a rotation. I think next year my approach might be different.

Beginning 2017-2018 #blaugust

It is the end of summer.  13 weekdays left of summer (edit: now there are only 8 – eek) – about 2 and a half weeks.  I am determined to remain positive in this time and moving right into the school year.  This summer has been filled with awesome accomplishments:

  • personal records in my squat, bench, and meet total
  • drove all the way to Florida, spent 8 days together, enjoyed Disney, and all the way back home with minimal problems
  • Jacob has been working on his writing skills
  • Jacob can put his head under water
  • redid our master bath about halfway – the rest will come sometime this fall or spring when we have the money 🙂 but I love it already
  • I’ve rejoined the Twitter community and am getting fired up to go back to school!

Goals I have for the last week and a half:

  • take my world powerlifting congress judges’ written test
  • get in this blogging habit again (I did a 30 day challenge before and it was a struggle IN MAY so I can only imagine what it is like in August with school starting BUUUUT I’m not one to back down from a challenge)
  • decide on a teaching initiative for the school year for myself and go full speed ahead (interactive notebooks, flipped classroom, replacing homework completely, or standards based grading).  All are worthy intentions and I need to stop thinking about how great they are and start moving ahead with at least one of them because I am tired of just being in the knowledgeable stage with them and not actually trying them out in my own classroom environment (this year 5 sections of Geometry which I taught for the last two years and now have SMART board lessons for the entire year, 3 regulars and 2 honors, of the 3 regulars 2 are cotaught, low-income school, Chromebook cart in classroom, 16 years of experience on my side)
  • clean my house like it is my JOB (as it is until next week at this time
  • present at the conference on Wednesday

Go #blaugust I got this and I hope you will come along for the ride

Introducing Solid Geometry with Marshmallows and Toothpicks #MTBoS

Today we began the last unit of the year in my Geometry class that involves solid 3-dimensional figures.  I opted to play a game with my students and challenged them to build towers out of marshmallows and toothpicks in a group of three.

The idea was to build the tallest free standing tower in seven minutes..IMG_6245.JPG

It was fun to listen to students as they determined what would make the strongest foundation, ensure that their structure did not get too heavy and topple over, and ensure that they had enough building supplies.

IMG_6243.JPGIt was a good activity and in the end we were able to define some terms for class as well:

edges – “toothpicks” – where two faces meet

faces – the flat “surfaces” of the “solid” (which in our case were invisible and the solid was not really all that solid at all)

vertex or vertices – “marshmallows” – where two edges meet

After the building, students then went online to do a Quizlet (I found one that suited my needs and adapted it) even though I had not introduced the terms.  It was awesome that they were able, through trial and error, to determine the meanings of some of the terminology.

The Friday Five #MTBoS30

I really enjoy doing this Friday Five.  This week I had PLENTY of ideas to choose from.  Here are some of the blogs and posts that I have enjoyed this week.  I’ll save the other ideas for another week 🙂

1.)  When I get a smartboard, I will have to remember this website.  This website QUICKLY turns your smartboard (or any device) into an interactive whiteboard

2.)  Got this idea for bellwork next year

• Mental Math Mondays
• Talking Points Tuesday
• Estimation Wednesday
• Tough Pattern Thursday
• Favorite No Friday
3.)  Geogebra application to introduce trig in geometry.  Here is a post on using Geogebra for a number sense activity.
4.) Two Truths and a Lie in a Math Class.  SOOOOO fun.  For Geometry, I would love to do this with quadrilateral properties.
5.)  Trashketball lessons on volume of spheres and linear system of equations. Awesomeness.
