## iPads! & A Math test this Thursday!

On Friday we got to play with our new iPads. They were purchased through a special funding program that I applied for last year. We will be using the iPads to support our math learning and to create multi-media presentations. Watch for more coming up!

On Thursday we starte to learn how to use FRAMES, a stop-motion software program for digital story telling. We will be creating our own animations of stories in the near future, once we learn how to use the program. For more information about the program follow this link to Tech4Learning.

There will be a math test this Thursday for both grades.

The students have been given a test outline. We will review in class and they will get take home review questions that are modeled from the test tomorrow.

Here are the outlines:

## Show – Don’t Tell & Area of Polygons

Today in English we talked more about entertaining the reader.  It’s the author’s job to keep the reader interested.  When we tell it’s kind of boring, if we show, then the reader has to infer a bit and it’s more entertaining.

We started by talking about character’s emotions versus traits.  Emotions change frequently, often many times during one day.  For example, I may wake up late and my little sister is in the bathroom and I really need to have  a shower fast or I’ll miss the bus.  I might feel frustrated and angry at my sister.  Then at school I’m happy to see my friends and play during recess.  I’m even happier during math because it’s so fun….  ;0.  My emotions have changed.  My traits don’t change much, or if they do, it happens over time.  For example, my daughters are both really creative and love to draw.  This is true no matter what they are feeling.

Here is an example of telling about an emotion:

This sentence is very boring.  It tells me that Bill is boring but it doesn’t show me.  This one is much better:

After we looked a several examples of an author showing emotions we did a little drama activity.  The students were gieven a scerario and they had to act it out, showing the emotions of the character they were playing.  I tried to post all the videos about 10 times and something wacky was happening with the blog, it posted the same one over and over so I will try again tomorrow. If you want to watch them over on my channel on YouTube here is the link to my channel. http://www.youtube.com/user/ErinL1970?feature=mhee

Tomorrow we will write desriptive paragraphs that show, don’t tell a character’s emotions.

And the it was math….

We are still working on Area & Perimeter.  The grade fives solved problems in their text books using the area of a rectangle:

The grade 6s had a problem that required them to figure out how to find the area of a square:

Then they cut the square into two congruent triangles and figured out the area of those (we did not give them the formula as they had to problem solve to get the formula themselves):

Most of the students did figure the area out using l x w / 2 = A

Mr. B consolidated the learning at the end by showing the 6s the standard notations for the formula:

## Infer, Infer, Infer……and Measure

We are doing some more inferring this week!  We read a story from the 2011 EQAO test and answered the questions.  Many of the multiple choice questions require inferring.  All of the written questions do.  When we infer we use evidence from the text and our background knowledge.  The story we read and the quesions 1-6 can be found here and a scoring guide can be found here.  If you look at the scoring guide you will notice that the answers include evidence from the text and the student’s own thoughts (background knowledge).

Over the next few weeks, we are going to be looking at inferring theme and the meaning of language – new words, metaphor, figurative language and idioms.

Mr. B, our student teacher, is back and he wil lbe teaching a unit on measurement, specifically linear measurement, area and perimeter.  Grade 5s will be studying the perimeter and area of triangles and grade 6s will look at quadrilaterals and paralellograms.  Today he read the class a story called Spaghetti and Meatballs for All by Marilyn Burns ( a Math guru!).  In this book Mr. & Mrs. Comfort hold a dinner party for 32 relatives.  Mrs. Comfort has figured out how to arrange their rental tables to seat everyone but Mr. Comfort and other families keep rearranging the tables as they arrive.   Of course, they can’t all fit at the table as they get pushed together as they lose at least two seats every time.  Eventually, they end up with the original configuration that Mrs. Comfort carefully thought out.   The students’ activity was to find as many possible table arangements for 20 people and to compare the area and perimeter.    The students used square colour tiles to model the arrangements.  Alas, I forgot to take photos today 😦

The big idea behind this lesson is that the area can remain the same and the perimeter can change or vice versa, the perimeter can remain the same while the area changes as in the story where they only had 8 square table to use so the area was alway 8 tables squared.
