Khan Academy set up instructions.

Directions for Khan Academy set up.

1-      Check your email and accept my invitation.

2-      Take the pretest.

a.       Once you accept the invitation a new tab will open and you’ll take a pretest

b.      Do the best you can on this test. If you don’t know the answer just click on “I haven’t learned this yet”.

3-      Once you finish close the “dashboard” and chose a mission.

a.       The default mission is “the world of math”, which is pre-selected for you. You’ll need to change this.

b.      Click on the drop down arrow next to “the world of math” and chose your grade or math level (Math 8, pre-algebra, algebra 1, etc…).

4-      Once your mission is chosen you’ll be able to learn and practice topics within that mission in addition to the recommendations that I ‘ll send to you.

lesson 7.4 to 7.6

Lesson 7.4, p398, ex 3.

-       This is a classic math problem. Click on the link below to watch a video just like example 3 on p398. Our math book uses “A” for Airplane, but in the video the teacher chose “P” for Plane. Other than this minor difference it’s the exact same problem.

-       Remember that the wind will affect the  total speed (or ground speed or still air speed – all of these mean the same thing) of the plane.

-       If Plane goes with the wind, then Total Speed = speed of Plane  + speed of the Wind.... that is:  S=  P + W

-       If Plane goes against the wind, then it will go slower, so Total Speed = speed of Plane – speed of Wind.... that is: S = P – W .

-       Check out the video. It’s a little complicated but hang in there. You can do it!  http://www.youtube.com/watch?v=yla2bk7jB_A
