Ch-Ch-Changes (Classifying Triangles)

10 Jul

Changes are a part of life and, let’s face it, some changes are better than others. We’re hoping this new upcoming change will be one of the better ones. June marked the end of teaching Grade 6 and September will usher in partner teaching on Grade 4/5 and Grade 4 classes. Due to numerous years in Resource teaching roles we have never taught a split grade before. So, there’s a bit of nervousness about the move. Doesn’t help matters that the teacher who has left the position is considered a guru and mentor by many. Maybe it’s more than a little worried. Have never taught grade 4 before either. Okay, flat out panicked!

Guess it should be brought up that the change was requested. It wasn’t forced. It truly seemed like a good idea at the time. Of course, so did all of those mock turtleneck short sleeve shirts we once owned. We are going to focus on the potential to learn and try something new. Did we mention that we also owned a pair of MC Hammer style of pants? We may not be the best judges of what constitutes a good idea. Now, the panic is for other reasons – does anyone have a picture of us in those pants? Fingers crossed for a “no” on the pants and fingers crossed that this career move is actually a good idea.

If you are following us for math ideas, never fear, we have a lot of math activities that we still plan on sharing with you. In fact, it will be a math freebie today. Below you will find our Interactive Notebook for classifying triangles. No particular reason why we selected triangles.

Enjoy the freebie and, most importantly, enjoy your summer. We fully intend to — which means see you in late August:-)

Symmetry Interactive Notebook

13 Mar

January and February felt like the same as always. Very long and very stressful. Then, March arrived and it seemed like Spring was truly on the way. Whammo! One last hurrah at winter. Another day with barely half a class and the sad knowledge that you will get to teach the same lesson twice. Sigh. At least, the incredibly fast meltdown brings a bit of happiness … as well as mud and blacktop recess. Feeling like we’re back to the “fortunately/unfortunately…” post:-)

Guess what we are saying is that we are just doing our best to hang on until March Break! This year, we plan to vacation with our families together in a warmer climate. Our children are very excited about the prospect of being together for a week – which they could have done at home as well but, at least they’ll have better weather! Whatever you have planned for your break, take some time for yourself and relax. To help you further decompress, we have you covered with another freebie. Enjoy.

 

The following freebie is an interactive notebook entry on symmetry. Our expectation is that students are able to sort polygons by lines of symmetry as well as rotational symmetry.

Geometry & Space: Constellation Angles

11 Feb

Report cards have been submitted and we are ready for a break! Oh, what’s that? The Olympics are on, Valentine’s is coming up, Chinese New Year is on the way, Carnaval is ready to roll, and, for those in primary, Hundreds Day is looming as well? Oh. Yeah. Don’t forget the work you have to catch up on due to those ‘buses are cancelled’ days.

And, poof, just like that, the potential break was gone!

Times like these make you want to hide in your classroom and hope that nobody catches a glimpse of your shadow – a possible sighting could mean another six weeks of unrelenting “fun” activities for you to participate in.

We’d like to write more but we just got prompted for this term’s IEP expectations…

We suggest you find a good spot to lie low until March Break. Good luck!

Unrelated –

Even though it’s really never been used for much, we do have a Facebook site as well. Lately, we’ve been wondering what the heck to do with it. Ignoring it hasn’t really done anything for us. We decided we will use it as a place to post quick ideas or maybe examples of student work. A place where you can get some ideas. If you want to check it out, you can find it here:

We don’t have anything up yet but will soon.

 

To help you out, we have this geometry and space activity.  Our space unit happens to coincide with our geometry unit. So, we decided to have students label and measure the angles they could see in a given constellation. The page also requires a research component. For us, it just  means looking at their notes for the most part. They do have to locate information on their given constellation. We do it as a partner or small group project. It has 9 constellations – an example is located below:

Rotational Art

21 Jun

During a recent unit on transformations in geometry, we decided to combine math and art. We have done this before with Wassily Kandinsky’s concentric circles and an attempt at a perimeter art. While we would happily do Kandinsky’s circles again, we definitely need to revisit the perimeter art idea!

In art, we had been looking at the Pop Art movement through the works of Jim Dine and Keith Haring and were to continue with a look at Andy Warhol. We decided to take the Warhol lesson and mix it up by adding in the concept of transformations. We focussed on the idea of a 4 quadrant approach, bright colours, images from pop culture and, the requirement to complete one of each transformation. Students needed to reflect, rotate and translate their image. How they did this would be explained in their artwork reflection. Since it was one of those last minute decisions the lesson itself needs some work but the overall idea yielded some great artwork!
