This year was great. I had awesome students, great collaboration with colleagues and daily reflection. I took some time after school wrapped up to go back and read through all my posts. I noticed that first 70 or so were pretty rough. I was in a weird place; trying to establish credibility and write like all the other bloggers out there I look up to, yet at the same time make my posts unique.

At times blogging every day was stressful. There were a couple moments out there where I almost threw in the towel… I spent 5+ hours each Sunday putting together fresh and new lessons for algebra and geometry (I didn’t reuse a single set of slides I created last year… mostly because of a transition from PowerPoint to SmartNotebook). But long story short, Sundays, 1 to 2 additional hours of prep each day and blogging wore me down after 38 weeks. Thanks to all of you, I made it.

This blog held me accountable in providing top notch lessons for my students each week (I dreaded the days where I had to write about using a Pizzazz or Kuta worksheet). I was also able to reflect each day on what went well or not so well, which, in my eyes is extremely important.

Basically, I am trying to say I am happy with all the improvements I made throughout the year.

But…I still want to be better. a lot better.

Here is what the future holds Quadrant Dan and myself…

  • I am really happy with the number of lessons I have stock piled on this blog. Next year, I will not be continuing a daily blog. I do however plan to post frequently. I want to dig deeper though and increase the quality of my posts, rather than quantity.
  • The main reason for the discontinuation of daily posts is next year I gained another class. I will be teaching algebra, geometry and IB math studies. The IB class is going to add an an enormous amount of work to my plate. Plus, I still have a lot to do for algebra and geometry; three preps will be intense.

I am excited for August to roll around and start my third year. Feel free to tweet at me @danburf, comment on an old post (I love questions), or drop me an email at anytime. Let’s keep these great conversations rolling!


Day 180: This is it…?

Ok, I have to come clean… we technically have two days of school left . Two snow days earlier this year, added two days to the school year. According to the calendar we are done today, however, June 11th and 12th are just-in-case “Snow day make-up”, which were put to use this year. But today was my last day of instruction, Thursday and Friday are all finals.

Algebra started off by filling out Who I am… Now. I hung onto the copies they filled out on the third day of school and passed those back today. It was fun looking at how their personalities and interests changed throughout the year.

After, students pulled out their phones/tablets and filled out another Teacher Report Card. Their responses were awesome. It is funny how students want their peers to think they are giving half assed responses, when in reality, they are meaningful and well thought out.

I made the mistake of not monitoring a student taking the final early close enough… So I had to reprint all the finals and shuffle the answers (I think there is a test of mine floating around).

While printing the tests I found these in my mailbox:

I have a lot on my mind, most of which I want to write about. I am planning on re-reading my [Almost] 180 posts then writing on final post to bring closure to this 180 blog and by then, will hopefully have a game plan for what I want to do with this whole blog thing next year.  I keep coming back and adding paragraphs to this post, it is kind of like the first few days of summer; I don’t know what I am going to do with myself now.

One thing for sure… There will be more posts from me in the future.

If this is it for you, thanks for coming by. The amount of feedback and positivity I have received from this blog shifted and accelerated the growth my teaching practices in the best possible ways.I hope you continue to swing by next year.

Day 179: A look back

Jeopardy Review today, if you need something last minute, this is a fun way to spend a period (heads up, there are a few errors, it is fun getting students fired up about them though. I am keeping ’em for next year)

Anyways, Back in August I posted about this 180 day blog thing. I want to take a little time to re-visit the goals I put in place.

My Goals:

  1. Get plugged into the math blogosphere
  2. Challenge myself to always be better
  3. Accountability
  4. Provide resources for others


1.  I have met quite a few people over the last year or so, Twitter + this blog + other blogs have served as a corner for meaningful discussions. I have neglected Twitter though, I pretty much exclusively use it as a way to get this blog out there. I wanna work on that next year.

2/3.  Looking back, 2 and 3 pretty much go hand in hand. In my eyes, a successful teacher holds themselves accountable to always bettering themselves. Long story short, I spent hours prepping each weekend, were interesting enough to write about each day. This was really hard and became exponentially harder as the year went on.

4.  The amazing amount of support the #MTBoS community has provided is unimaginable. It is excited to see the community grow and great to be a part of it.

One more day…

Day 178: Review

Today was hot, I’d bet a lot of school across the country felt the same way. I gave algebra and geometry a list of the concepts that will appear on the final exam, suggested problems to review and set them loose. Finals are Thursday and Friday of this week so we have a good amount of time to review.

Day 177: Skittles

Last night I went and bought 8 pounds of Skittles; I had a fun conversation with the cashier.


Algebra looked at the color distribution of the different sized bags of skittles and made some conclusions on the data.

Here’s how things went.


I threw up this picture and asked ’em how many Skittles thy thought were in the package, then their estimated percent breakdown of each color.

After, I put this up and asked if it changed any if their answers.


They saw the number of each color and calculated the percentage of each.


111 Skittles isn’t a great size to make any conclusions, they asked for a larger bag and then made the same estimations.




389 Skittles isn’t really enough to make conclusions either… the data was everywhere.

Then, I pulled out a 2 pound bag of Skittles, broke students into groups of 2 and had them find the frequency of each color.

I put together a quick Excel document and had running totals throughout the day.

The results of each 2 pound bag were different, but when we put them together and looked at a sample size of 4338 some interesting talking points emerge.

SkittlesI am excited to hear what students have to say/conclude from this data on Monday.

Day 176: Perfect Squares

In geometry I put this up on the board as they walked in.

1, 4, 9, 16, 25…

I asked ’em what patterns they saw.

  • Perfect Squares
  • First difference is always odd
  • Constant second difference of 2
  • y = x²

I was wondering if they would come up with this:


I eventually put the pattern up and asked if any square multiplied by 4 is always a square. They said yes and talked about the shape a dot representation of the number would make when multiplied by 4.

Then a student asked “Is a perfect square multiplied by a perfect square also always a perfect square?” 

Well (a²)(b²) = (ab)²

We had a great 5 minute discussion about this, I had never thought of the product of two perfect squares, it is always fun when I learn along with them. I don’t talk enough about number theory, this was a great exercise in developing both number theory and sense.
