Today we will be looking at Khan Academy.
First I will need your email addresses - these will be used to communicate within Khan academy and other apps.
Just click on this form and enter the informations:
http://bit.ly/UErnMP
Next you need to visit the web site (not app) so you can create an account (if you already have an account sign in and read below).
Go to www.khanacademy.org/
Now select the "sign up" option in the top right corner.
I would NOT recommend linking your google or facebook accounts but instead enter your information below (you do need an email address).
Once you have an account and have signed in visit your profile by clicking on your name at the top of the page. Next go down to "coach" and enter my ID (my email address): [email protected]. This shares your Khan Academy stats with me - the advantage of this is I can give you work habits credit as well as rewrite opportunities if I know you have been doing extra practice or watching videos.
Main Lesson
Our content topic is lesson #6, factoring trinomials with a leading coefficient > 1 (a bit of a mouth full).
Start by opening the Algebra Tiles app. Now create, sketch and factor the following trinomials:
1. x^2 + 5x + 6
2. x^2 + 7x + 6
Describe a "short cut" to factoring these types of trinomials (without a model).
Now create, sketch and factor the following:
3. 2x^2 + 5x + 2
4. 2x^2 + 7x + 6
How are these the same and different from the trinomials above?
Feel free to explore the algebraic steps for this type of factoring by selecting videos (on this site) and by selecting the Khan academy video for factoring with a leading coefficient greater than 1.
Practice
Work on Unit 3 Lesson #6; p. 177 #5-8, 10, 13, 15-18, 21 alt
If finished practice this method (on an earlier factoring method) on Khan academy - don't forget to sign in so you get credit!
Wrap up
Complete the exit slip activity on the Socrative App.
