Math is fun, right? And very applicable to the ‘real world’, despite what all of those people who say they never use algebra – ever- tell you. But we all know it deep down: math and physics rule our lives.

Personally, I am a fan of the cosine coaster…

Just checked out Easy Measure and was wowed by the coolness:

EasyMeasure shows you the distance to objects seen through the camera lens of your iPhone or iPad. Simply aim your iPhone/iPad to any object in your surroundings, and EasyMeasure displays the distance towards that object on top of the camera image. With its amazing 3D camera overlay grid, using EasyMeasure is very intuitive and easy!

Not sure how I would use this, but now I want to measure the distance between things- room measurements, perhaps?

A very useful list of apps, perfect for use the classroom!

Hidden Experts in the School: Mr. H, Math Teacher, Science Teacher and Ed Tech duderino

Mr. H: Hidden expert

Mr. H: Hidden expert

One of the unexpected but amazing outcomes of the iPad survey I’ve been conducting is that I am ferreting out the hidden experts in the school. Okay, in all fairness, my library seems to be the black hole for all rumours and gossip and grapevines (ironic for a place of knowledge, I know. Great on book knowledge, not so great on people knowledge) and I am probably the only one in the school who didn’t know about this, but still. Yay!

Mr. H is an Ed Tech dude! As well as being a teacher, he has had experience in the business world, and worked for LEARN where he could meld his interest in technology and education.

When asked about whether student engagement increases or decreases when he uses tech in his classroom, he brought up a point I had never thought of:

The students respond well if you start using a technology they have never seen before. It has an impact..they have the ability to suck it up so fast. Because button pushing is now in their DNA, when you bring something new to them it excites them.

He also thinks that that integrating technology in education is essential:

You have to put these [iPads, probes, computers] in kids’ hands because that is the environment they are going to work in.

My H. gave me some excellent places to find resources for integrating technology in the classroom. Most work on the iPad:

  • Phet: Interactive simulations (they don’t work so well on the iPad because of the pesky flash thingy- though some of the simulations are in java).
  • Edmodo: He will be giving a tutorial to our teachers soon about how to use it effectively in a classroom, so watch for it!
  • Schooladvice: This is his own website – Mr. H. maintains it as an unpaid, volunteer thing because he believes knowledge should be shared. Check out his Resources for teachers!
  • Sharemylesson.com: Thousands of lesson plans by teachers for teachers:

Thanks Mr. H!

Exercising my Dilatation Brain on the iPad

Once upon a yesterday, a math teacher asked me if there was something she could use to teach dilatations on the iPad.

I said sure!

and then quickly looked up what the heck that was ( a math genius, I am not). First question: what is the difference between dilatation and dilation? Has the math language police dropped the ball on this one? Are they the same thing? Please oh please math genius people, could you clarify?

Not that I was going to let a small issue of semantics stop me, not I. I was going to figure out how to dilatate on the iPad if it killed me.

It almost did, but not because of the iPad thing. No, it is because I am a reluctant mather, which in a way made me a perfect guinea pig as my skill level is on par with a 14 year old.

So the first thing I did was go to the amazing programs other Math teacher has adapted to work on the iPad:

I clicked on Transformations (I knew that much) and went straight for dilatations, skipping all the other steps. Yep. I’m cocky.

Ummm.

I had no idea what to do, so I thought I would google a useful tutorial on my desktop ( I know. Cheating). But where was the center of dilation? How can I do anything without the freaking centre????

Could there be two ways of doing this dilatation thing? Oh no. What have I gotten myself into?

Then I remembered that Mr. Math teacher made helpful videos conveniently located at the bottom of the page (these are screenshots of the beginning and the end of the video):

And the answer!

But wait…You mean dilatation is just an intimidating word for making it bigger or smaller?  Like, you just have to multiply it by the second number there? I can do that!

So back to the exercises ( I got the first one wrong so I had to try again):

photoTake that dilatation! I totally kicked your butt! Now the only problem with this program is that there is no place to show your work- it is meant as an exercise tool for the students, as individual practice. Still, I am using an iPad, which means my calculations are only a photo away:

Aren’t you glad I’m not your student?

I thought I would try the same thing on the free version of geometry pad just to have a comparison:

Geometry pad allows you to save your work as an image or PDF as well as mail it.

Math teacher’s amazing programs are great for students to practice. It keeps a tally of how many problems they get right and how many they get wrong and also gives the answer when it isn’t correct. This is great for the kids who have grasped the concept and just need to practice it. Also, the video was super helpful, at least for me, who knew nothing about dilatation.

However, if you are a teacher who likes to see the process of your student even during their practice sheets, geometry pad is an option. The only problem is that the student will have to input the first triangle they need to dilatate as it is a blank graph. And it might be annoying to receive a lot of jpegs of problems…However, it could be a good option in terms of presenting the concept to the class…

In conclusion, here is my brain before dilatation:

College students develop apps to help kids with algebra

Via USA Today

Here’s an interesting article about apps designed by college students to help 8th graders get over the algebra stump…

Includes mention of the following apps:

I would love to have the input of a math teacher on this- are these apps helpful? Would you recommend them to your students struggling with algebra?

Let me know!

 

What they are saying about the iPad this week

Or at least what my google alert filtered my way.

The first article I read was from PC magazine entitled Challenging the Education Status quo:

While other teachers are entrenched in a never-ending battle to get students to put away their smartphones and tablets, Jenks is putting them to use in his lesson plans. Upon entering Jenks’s classroom, each student is handed an Apple iPad (made possible by grants from the Wyoming Department of Education and the Hot Springs School District). Students can personalize their iPads and, basically, have open access to the Web. With the devices, they complete assignments, collaborate with other students (even those in other classes), use science-based apps, and go on research scavenger hunts by scanning QR codes with clues to the next location. Jenks’s physics, earth science, astronomy, and chemistry classrooms are largely paperless. They store assignments and other class documents in Google Docs.

 

Wait a minute. Don’t  we do all that?

Pause for a collective slap on the back, Traf. We are officially innovative!

The article goes on to confirm our philosophy regarding students and tech as well as our social media policy.

Here is another interesting article: Study Claims iPad App Boosts Student Skills.

Huge caveat: this study was sponsored by Motion Math app and the NoyceFoundation.

Still. Here is what they found:

Kids who used the app for 20 minutes for five days improved on a fractions test by an average of 15 percent compared to the control group. Using Motion Math also improved the kids attitudes about fractions by 10 …

This is interesting to me as a parent who, as I mentioned before am dealing with two children who have inherited my lack of math skills. (Which is too bad because I actually like Math. Especially the crazy advanced studies like topology, mainly because the idea of “properties that are preserved through deformations, twistings, and stretchings of objects”[definition from Wolfram Math] resonate with my philosophical soul, yo.

But I guess you gotta learn your fractions first.

Last but not least a very informative and easy to follow comparison of screencasting apps for the iPad:
