Here are the first two Prezi presentations. I hope to post the link to all of them, once they are completed. I have not viewed them from the blog and hope the links are correct.
This is Trine's:

We were to have some other students present, but there was a problem with the TDSB network.
In Grade 8 Math, the group just complete their final test, yesterday, on angle relationships in parallel lines. To prep for the upcoming unit on the Pythagorean Theorem, I am having them do some hands on work to explore the relationship of the Mathematics behind
a2 + b2 = c2 (that's spposed to be "a squared + b squared = c squared).

The next day, we continued in the spirit of drawing and cutting by having the students sketch out a triangle on a grid paper and then draw the squares on the non-hypotenuse sides of the triangle. I will add a few photos of the student work, but I will demonstrate an example:
The sample image I will now show, which I took from the John A Van de Walle text, also illustrates this work:
After this exercise, from yesterday, we took the drawings and then applied the Pythagorean Theorem to them. I modeled it with the sample question I did yestersday:
In Grade 7 Math the re-tests for Perimeter, I am proud to say that 3 students joined the club of scoring a mark of 70% and higher:
We will now be taking the Measurement unit into the area of area (
pun intended). To recap, here is the difference between the two:

Before any formula is introduced, I want the students to gain an understanding of what area refers to. So, we are doing a few exercises that will involve estimation and a bit of cutting. Last night's homework looked like this:
Some of the homework looked like this:

Eric's |

Eric's finger method |
|
Caleb's method |
|
Tamar's method |
The element of cutting is missing from both. It is not to say they are wrong because both boys came up with creative ideas. We'll do some cutting today and I will try to capture images of that. Another activity, a group one, will follow this up before we begin to look at the
nuts and bolts and formula for the area of a rectangle.
In the afternoon, we proceeded to cut, fold and draw on the rectangle homework from last night to discover which one was the largest.
Mrs. Cimesa (pronounced Cimesha) is a Student Teacher in our classroom from OISE Uof T (Ontario Institute for Studies in Education ). She is, originally, from Croatia.
Her placement will be for the next three weeks and a few days. She was a certified teacher in Croatia and in process of making her Ontario teaching status permanent. Mrs. Cimesa will be teaching the class a unit on Media Literacy, beginning next week.
