### Disgruntled Math Students

This year I have a group of freshmen for Algebra I that have a very negative attitude about math in general.

It doesn't matter if I teach a lesson, give them book work, have them do a group activity, etc. They are always dissatisfied with anything I give to them. I was hoping to get some feedback about how other teachers deal with the negative attitudes. Is there any activities that work particularly well with your challenging students? This group is really interested in music, so I try to… Continue

### Function-based approach strikes again

Teaching my 8th grade math class which follows all the GLCE's for grade 8, I've started to teach about various functions. The standard is:

"A.RP.08.01 Identify and represent linear functions, quadratic functions, and other simple functions including inversely proportional relationships (y = k/x); cubics (y = ax3); roots (y = ãx); and exponentials (y = ax, a > 0); using tables, graphs, and equations."

Based on A4A, my first thought is "How can I turn this into an exploration… Continue

### Graphing Calculators - Daily Use

Monday, January 11

Today students were using graphing calculators to explore the content they have learned during the first semester of their Honors Algebra 1 course. Together we explored the graphing function on the calculator and the table feature. We also graphed inequalities - it was one of my students who helped the others find and use the App which allows for graphing inequalities. Students seem very engaged.

Today students used the… Continue

### Trouble shooting TI-83 and 84Plus

The most frustrating thing I have come up against.....

--> I can’t graph more than one equation at a time. <---

Are there funny arrows at the left of your Y= screen?

The illustration and solution are courtesy of Jesse Phillips, who cites this page from the Texas Instruments support site:

In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling… Continue

### Seeking geometry materials.

I have posted on the DIM site previously looking for a test generator for a geometry class. No one has this in our area. I have 4 informal geometry classes and it is comprised of many struggling students. I try to be creative and come up with interesting materials. The textbook we have is not very user friendly so I supplement with worksheets quite often. I have not found anybody who has a software edition of their text that can produce worksheets and tests. Please let me know if you have… Continue

### New Technology in the Classroom

I'm thrilled to share that I've been fortunate enough to receive a new Eno board in my room. It's similar to the Smartboard in that I now have a giant interactive computer touch screen located in my room. It's been an absolute dream this past week, and I can't wait to attend the official training session where I can learn even more uses in the classroom (as if I haven't used it every day anyway, without the training)! As a teacher from a small, rural school with extremely limited resources… Continue

### December Session

Our December session included some great activities that involved comparing linear and exponential data sets. I plan to use all of the material in some form for that unit in my classes. I particularly thought the Lily's Mussels activity could be more local with some information about the Asian Carp species that is about to invade the Great Lakes. I liked the repitition of finding the equation on the calculator numerous times. I think this strategy will work for some students that get lost in… Continue

### January Session

The January session included an activity that I remember seeing somewhere in college, but I have never done with my classes in the same way. I like the open ended type of activity like this that involved many possible strategies for a solution. I also liked that the negative side of the domain was included. I don't think that my Algebra 1 students would understand the negative domain values, but I think it would be better suited for Algebra 2 students.

I also really liked the Egg Launch… Continue

Three college students go to Florida on spring break. The room costs 90 dollars so they each pitch in 30 dollars. A while later the hotel clerk notices that the price is on special today for only 85 dollars. He instructs the bellhop to take 5 dollars and return it to the three students. The bellhop gives each student 1 dollar back and they instruct him to keep the 2 dollars as a tip.

So now each student paid 29 dollars. 3 times 29 gives 87 dollars. The bellhop has 2 dollars. This… Continue

### Kudos to Algebra 4 All

I recently presented at a Best Practices Conference. A participant was asking me which professional development opportunities had the most impact on the changes I have made in my teaching. She followed her question with "Have you attended Algebra 4 All? That was awesome!" Kudos to the facilitators and creators of the Algebra 4 All Sessions.

### Using these lessons in other classes

Boy has it been a while! I just wanted to drop a note here and say that I modified the stations of algebra - linear activity that we did in a4a for my 7th grade class as we began a discussion on direct variation. I used it to slowly introduce what an direct variation equation looked like and how the 'k-value' made the graph change. I then opened up exploration with negative slopes and intercepts to lead into an understanding of linear functions and how the slope and intercept effect the look of… Continue
