You will be using a website to investigate and practice measuring angles, and then you will be asked to create and measure one acute and one obtuse angle. You will save a picture of your work by creating a screen shot and pasting the screen shot into a new Word document.
Instructions:
| Step
1: |
Go
to http://www.amblesideprimary.com/ambleweb/mentalmaths/protractor.html
and watch
the short
introduction video until it begins to repeat. Select
"Skip Intro." Then, select "Make and
Measure." See example.
|
| Step 2: |
Click on the +
sign to create an acute angle. Then, click and drag the
protractor to the correct
place for
measuring the angle. See
example. |
| Step
3: |
Type
your angle measurement into the box
in the lower right corner of the screen, and click
"Check"
to see if you
are correct. See angle box and "Check"
button. |
| Step 4: | If
you are correct, you will get a
"Perfect!" message. Move the protractor to the angle again,
type in the
angle measurement, but do not click "Check" this time. See
example. |
| Step
5: |
Make
a screen shot by pressing "Ctrl" and
"Print Scrn" keys at the same time, and then "Ctrl"
and "C" keys.
Open a new Word document and press "Ctrl" and "V" keys to paste your
screen shot into the Word document. Save this as "Acute
angle-(your name)" in your own folder. |
| Step
6: |
Repeat
this entire process, but this time
make an obtuse angle and label the saved Word document "Obtuse
angle--(your name)." |
