Triangles

Triangles today!  Triangles are everywhere...  Just take a look!



In class, we learned how to find the area of triangles by cutting, arranging, calculating, pasting and measuring!

The formula for finding the area of a triangle is...

A = b X h / 2  (base times height divided by two)

Check out this site, Mr. Glosser's Math Goodies, to learn a bit more about finding the area of a triangle.  It even has some practice examples down on the bottom of the page.

Tonight's homework is the triangle worksheet.
On the "Practice Worksheet" side, please skip numbers 4, 5, 6, 13, 14, & 15.
On the 4-5 side, please skip numbers 3, 6, 9, 12, 15, 16, 17, & 18.
AND please don't forget that you should use a calculator!!!

Good luck and have fun with this!  The posters from class should be up this afternoon and I will post some of the pictures from class on the blog tonight!

-Miss K  :)
