# Day 17 (09/24/14)

Stats & Data: We are working hard on our infographic projects. I always struggle with how much class time to give to finish projects in this class. I often wonder if I give too much time and my kids are happy to just pick away at their projects.

AP Stats: My students had to take a statistics pretest and attitude survey from Hope College. We are a part of a study involving ebooks and statistics achievement. This is year two of the study.

Algebra 2: We started a solving systems foldable today. We worked on solving systems using graphing. We also downloaded the Desmos app and explored solving systems with this application.

# Day 16 (09/23/14)

Letting the tests out this year.

AP Stats: Empirical rule today. I wonder if I should even teach the empirical rule. I mean we can solve any of these problems using z-scores and the normal table. I’m going to have ask the experts about this.

Stats & Data: Great day of infographic work today. Everyone on task. Everyone getting stuff done. Our warm up today was a type 1 writing prompting my students to articulate questions they were having on the project. I used a google form to collect their responses and was able to quickly answer the questions. I had them put this assignment on their agendas to get a completion stamp. I think all warm-ups will go on their agendas. I believe this will increase completion of the warm-ups.

Algebra 2: Nice work today on graphing linear and absolute value inequalities. This is the last week of our review modules so we need to use our time wisely. We will be solving systems graphically tomorrow.

# Day 15 (09/22/14) Test Corrections

Well, the tests didn’t go as well as I had hoped.

AP Stats: As I was grading the describing distributions tests this weekend, I was shocked my students had issues with shape and relative position of mean and median. I thought we had that spot-on. We explored some geogebra interactives, we had some of the questions on the practice test, we put the relationships of shape and center on their review card in their INBs, … So, test corrections are in order. Mornings, lunches for a few days to earn some points back.

The lesson I learned from this issue is I new to be doing more formative and interim assessments. I should have known my students issues with this concept before the test, not as I’m grading them. Lesson learned.

Stats & Data: My guys are figuring out data mining is not easy. They are really digging for data to include graphically in their infographics. Good luck, my students.

# Day 14 (09/19/14) Infographics!!!!!

AP Stats: Test today over describing distributions. Our test consisted of four real-deal AP multiple choice questions from released tests and 4 real-deal FRQs. Three of the FRQs were deconstructed or fleshed out or guidelines added to the questions. Free Response questions are pretty hard, especially for a first test. I likely gave too much additional information, but it was the first test. I received some great advice for next year from @druinok: Use a different font for the additions so the kids will be able to see what information was added. Will do. As we continue our AP Stats journey, each test will have less added information or guidelines. Baby steps, I guess. I’m really looking forward to grading them. Yeah, I said that. I think my students got this stuff.

Stats & Data: We started our infographic project today. Each student will create a digital poster that tells a story about a topic that interests them. We are a 1-1 iPad school so we are using Keynote slides to make our info graphics. I wish we had the ability to make the “pro” infographics. I’ve seen the site visual.ly, but have not determined a way to use it for my classes. Any suggestions?

Algebra 2: Great progress on our review modules. Next week will be our last dedicated time to complete these individual modules. Any unfinished modules may still be completed at lunch or after school.

Looking forward to a wonderful Pure Michigan fall weekend.

# Day 13 (09/18/14)

Blogging from an iPhone watching a soccer match.

AP Stats: First test tomorrow. Kids took a practice test and we discussed the answers today. Good luck, guys.

Stats & Data: We had some fun calculating standard deviation by hand. Just one. Then we looked at different graphical displays to determine which had the largest standard deviation. We didn’t have time for the geogebra activities today. Sounds like a good warm-up tomorrow.

# Day 12 (09/18/14)

AP Stats: We are getting ready for our first test on Friday. We started the day with an Ogive FRQ for our warm-up. I was pretty impressed with how the guys fared. Then I had my students spend 10 minutes creating a large index card of stuff to know about describing distributions. We will be creating a flip book of sorts in the back cover of the INBs with chapter review guides. I will post a picture tomorrow. These will be great review guides that the kids can look at regularly. I read about this idea somewhere. My memory thinks it was an AP Calculus teacher that posted this idea. I wish I could give proper credit, but my mind fails me again. Homework tonight was to finish a practice test. The practice test consisted of six real deal multiple choice questions and three FRQs.

Stats & Data: Quiz today on constructing box plots and calculating outliers. Then we watched the Against All Odds Series video on standard deviation. I like the new updated versions of these videos. We will be calculating standard deviation by hand for a few small data sets.

Algebra 2: Lines, Lines, Lines!!!!

# Day 11 (09/16/14)

AP Stats: We are winding down the learning targets for the first unit. We did a ogive booklet in class today (thanks to @druinok). Funny name, ogive. I told my students it took a couple years of teaching until I really understood ogives. No worries, now I got it! The kids will do an ogive FRQ tomorrow for their warm-up.

Stats & Data: Whew, finally finished the “30 Second” activity. I really held the kids to the CCSS mathematical practice of PRECISION. Labels, units, titles, scaling…

Algebra 2: We are review lines today so we completed a graphic organizer. We talked about the differences of the different forms of the equations of lines. My students prefer:   y = mx + b  I would rather work worth with: y – y1 = m( x – x1). I like discussing the structure of the point-slope formula. It really ties nicely into transformations of the family of functions.

# Day 10 (09/15/14)

Where did the weekend go?

AP Stats:

We started our day by talking about the FRQ I graded over the weekend. There are so many ticky-tack parts to the FRQs that it’s really difficult to write a perfect FRQ. I have the kids just redo them in iterations. I graded the FRQ out of eight points instead of the usual four. Most of my students scored 6/8 for the their first iteration. They may correct them and turn the FRQ in again. Then I grade them again. I do a lot of grading in this class.

After the FRQ review we explored outliers and their effect on measures of center and spread. I used home run data from Baltimore Orioles’ outfielder Brady Anderson. He was that scrawny guy that suddenly hit 50 HRs. Yeah, during the steroid era. The kids figured out mean and standard deviation are not resistant measures, but median and IQR are resistant.

Stats & Data:

We completed our Chapter One unit organizer today and worked on the “30 second” activity. The organizer is attached below.

Algebra 2:

We are finishing our work on solving absolute value equations and inequalities. We completed our organizer and finished pre-quizzes and quizzes. The organizer is attached below.

# Day 9 (09/12/14)

A really fun Friday at Holland High. I start Monday, Wednesday, and Friday mornings with breakfast duty. It is such a fun time meeting, greeting, and talking to so many students each morning. I try to say hello and wish a good day to everyone in the cafeteria.

AP Stats: Full-on describing distributions FRQ blitz todayWe completed one FRQ together as a class. Then my students worked in groups of four to complete three others. We made a little folder page in our interactive notebooks (INBs) to house the FRQs.

I used the green, yellow, and red cup system to indicate if the groups need any help. Here are some pictures.

The group with the red cup was having trouble determining how the shape of a distribution effects the relative position of mean and median. We looked at the geogbratube interactive I mentioned yesterday to help clear up their confusion. Here is the link again.

Most groups completed 3 out of the 4 FRQs. I had them select one of them for me to hand grade for a quiz score. The remaining unfinished FRQ is the HW for the weekend.

I had so much fun walking around the room and listening to conversations around the FRQs. I have to constantly remind myself not chime in to their discussions unless I am needed.

Stats & Data:

We completed a quick quiz and worked on box plots and outliers today. We had to review order of operations today as some students were having trouble with the outlier formula (Q1-1.5(Q3-Q1)). After we constructed a few box plots by hand, we used Statkey make some box plots. The graphs constructed on Statkey were different with different outliers. Yikes, we discussed that the program may use a different method for calculating the quartiles and outliers.

My students really are enjoying their “agendas” There is something about getting stamps that keep you motivated.

I made an organizer for the describing distributions last night for my students. They just seemed to be a bit scattered with the big ideas. I hope the organizer with help.

Algebra 2:

We are reviewing solving absolute value equations and inequalities. I made a organizer around the three main types we were solving. I attached it below. The kids are completing Algebra 1 review modules for the first few weeks of this course. I really enjoy working shoulder to shoulder with these guys. I get such a great feel for the math skills, and I can give individual help.

# DAY 8 (09/11/14)

I’m loving the cooler weather here in Michigan. Less worries about dress code violations.

Stats & Data: We are learning how to construct box plots today. I’m surprised very few of my students recognized a box plot during the introduction. After practicing constructing a couple of box plots most students commented they didn’t like them and thought other plots were better. I think when we finish the 30 second activity and compare distributions using box plots they may see their value. Calculating potential outliers on the docket for tomorrow.

AP Stats: Box plots and outliers today for this group. We also explored a couple of geogebratube activities that address the relationship between mean/median and the shape of a distribution. The links are here and here. A big FRQ blitz tomorrow.
