Based on the Triangle and Quadrilateral exercise from yesterday, here's a cool webpage that demonstrates how the sum of the interior angles of a triangle equal 180 degrees.
I am having some difficulty uploading this video on Interior and Exterior angles:
While looking for games for the Grade 8s to play, I came across this pretty detailed page on Parallel lines and the angle properties associated with them.
This is a video that will go through what is known as Alternate and Corresponding angles.
Yet another video. Grade 8s, if you want to go through a very slow, but informed review of angles (some of the work you will not get to until high school), please have a look at this:
As we work our way to more complex angle relationships, I wanted to upload 2 images of a student using a protractor to measure an angle. At first, he has the placement incorrect, but then he corrects it, so he comes up with the right answer.
Today, the Grade 8s had a look at Opposite Angles.
We will be returning to the 2 shapes we constructed yesterday. Here is the sample I did with the correct measurements and totals.
Links for some Mathematical Games
Grade 7: There are enough links here to help you review some of the work we have done so far.
This Funbrain website activity is probably the best place to start because you can select the level of difficulty for either Perimeter or Area of both: http://www.funbrain.com/poly/index.html
Another solid review of Perimeter and Area. You may either select from Area or Perimeter when you click on the link: http://www.bgfl.org/bgfl/custom/resources_ftp/client_ftp/ks2/maths/perimeter_and_area/index.html
An Area and Perimeter game that uses a grid. You can check your answers, once you are done:
This is a virtual version of the activity we used with Geoboard and elastic bands:
A Geoboard like activity that looks at both area and Perimeter from PBS Kids: http://pbskids.org/cyberchase/media/games/perimeterarea/perimeterarea.swf
A game that involves an understanding of both Perimeter and Area. You are in charge of designing the layout for a party: http://www.mathplayground.com/PartyDesigner/PartyDesigner.html
Grade 8: There are not as many "fun" games for this part of Geometry, but I think you will find the interaction engaging.
This is an angles game in the spirit of Jeopardy. You have played a game like this before for another strand of Math: http://www.math-play.com/Angles-Jeopardy/Angles-Jeopardy.html
Not so much a game, but more of a review of angles: http://www.ixl.com/math/grade-6/complementary-and-supplementary-angles
This is more of a game concerning Complementary and Supplementary angles: http://www.lessonpaths.com/learn/i/angles-2/xp-math-math-games-arcade-complementary-and-supplementary-angle-pairs-practice-free
I think Trine will like this game. It has the word Manga in it!!
