This page will come in handy for what we are doing in Grade 8 Math:

After watching some of the videos, I gave the students a handout (less the writing by me on it) illustrating some of these angle relationships:

This was posted back in early February and we are only ready to explore some of the angle relationships right now.  The Grade 8s recently completed a Math test with most students scoring above a Level 3.  This is work at Grade level and the group should be pleased with the hard work they put into the Study sheets they did in preparation for the test. 

 If students were not pleased with their mark and scored below a Level 3 (less than 70%),  doing a Rewrite is always an option.

As for the Grade 7s, I decided to hold off on introducing the new concept of Area until the Re-tests are completed for Perimeter.  The last of our review was from today.  I will post some images of the work we did today:

This question proved to be a bit of a challenge for the class.  It involved figuring out the different dimensions of a rectangle that has the same perimeter.  I posted a similar example on yesterday's blog post.

Megan helped figure out the ascending and descending pattern of the width and length of the rectangle in question (it had a perimeter of 20).  To demonstrate this, I used one of the games we used a few weeks ago to prepare for the test.  It is basically a virtual geoboard.  The link for it is from the list of games I re-posted yesterday, I believe.  Note:  the perimeter is the same, but the dimensions of the rectangles are different.

 This example shows how Junior used the correct formula for calculating the Perimeter of a rectangle.  Instead of using the typical formula of P=2(l+w) -- which means that calculating the Perimeter happens when you multiply the sum of length plus width by 2 -- Junior used something called the Distributive Property to calculate the answers for part a + c.  He multiplied the length and width by 2, but did it separately.

For part a, he could have done it like this:  P = 2 (3+2)
                                                                P = 2 (5)
                                                                P = 10 cm

Great thinking, Junior!

Onto a different subject.  The Success Criteria for Mr. Beaupre's Geography Prezi assignment is here.  Actually, it is more of the evaluation form, but this is how the students will be graded:

And, yet another Success Criteria chart!  This one is for the Prezi research assignment.

HOMEWORK:

Grade 7:  Final Perimeter test tomorrow, IPRC letters returned
Grade 8 : Math textbook homework
Both:  Tracey, Trine, Alyssa, Caleb to present their stories
