 * Learning Goals**

My learning goal(s) for length and perimeter is:

__1)__ to have a good rough estimate of centimeters without measuring __2)__ to be able to measure the area of a right angle triangle __3)__ __4)__ __5)__

To achieve my learning goal(s), I must learn: (What specific knowledge, information, skills do you need to acquire?)

To acquire that knowledge, I will use: (What specific resources will you use?)

To determine whether I have achieved that goal(s), I will: (What criteria will you use to determine whether you have met your goal?)

To demonstrate that I have achieved my goal(s), I will: (How will you prove that you have achieved your goal?) i estimated that my keyboard was 45 cm. Its was actually 43 cm, so i was close. i estimated that my couch was 185 cm. its actually 206 cm. my guess wasnt too bad. i now know that if i have a right angle triangle like the one below i times the height and length (12x18) as if it were a rectangle and half that as theres only half the rectangle e.g. for my example L x H would be 12x18 which equals 216. half that and you get 108 cm!
