Algebra for All does not mean access for All Achievement Gaps
Equitable Teaching Practices (student-centered defined by NCTM) Reflection, dialogue, multiple
representations, and regular feedback
Google Your Math designed to provide opportunities to access Algebra at home.
Research Question: How will students use Google online environments in Algebra? How would they dialogue? How would they collaborate? Who will use it? How will it help them in Algebra?
Principles of Knowledge Building (Scardmalia & Bereiter, 1991, 2006) Students take responsibility for their learning by planning,
execution, and evaluation Advancing the current understanding of individuals within
a group, at a level beyond their initial level of knowledge
Sociocultural Learning (Vygotsky, 1978) ZPD and dialogue as a mediation tool
Motivation (Deci, 1995) Using technology for flexibility – allows for student choice
and autonomy Reflective feedback
Communities of Practice (Lave & Wenger, 1991) Central and peripheral participation
Sustain an environment of collaboration and discourse outside of the classroom and increase student practice at home
Improve student performances in algebra
Reduce achievement gaps between student populations

Abe(9) – Easy to use “It was organized on the computer. I did not
have to keep track of it.” Katie (3) – Reliable
“I did go on even if I didn’t post. I still looked at what others posted. I didn’t post because I didn’t feel confident.”
Hudun (3) – It was okay “People posts answers. You could see how they
followed steps. It helps your grade go up.” Sherwin (10) – Improvement
“It helps because you can see other people’s answers and compare. The teachers can also explain.”

Jamar LETS JUST SAY I DONT REALLY UNDERSTAND ANY OF THIS IM CONFUSED
April 710:26am
Angelo response from math maniacs......the answer for this problem is 9x^2+12x+4
April 710:30am
Katie response from the variable babes: the answer is not 9x^2 because you can't make a full rectangle or square the correct answer is 9x^2+ 12x+ 4
April 710:33am
Jorge this is for team alpha pie 9x squared + 12x + 4 count each one
April 78:22pm
Sherwin response from slopes: If u lay out the tiles of 9x squared 2+4, it doesnt make into a full rectangle the correct answer is 9x squared 2+ 12x+ 4
April 88:10am
Abe Sherwin thanks for posting that for our groups
April 89:15am
Mazen 9x^2+ 12x+ 4 because 9x^2 its not a rectangle

Armando those aswers helped me a lot thanks

Mrs. S Math maniacs, Thank you for submitting a solution, but can you explain how you got your solution? (any and all can respond from math maniacs)
Apr 10 5:43am
Mrs. S Armando, can you explain why these answers helped you a lot? What do you think the solution is and why? Why is the solution NOT 9x^2 + 4?

Hudun don't you distributed ? Anybody help!
Apr 105:37pm
Mrs. S Hudun, Yes, distribution is the key to this process. However, when using distribution, you need to consider both dimensions. Try using the box method we learned in class on Thursday and Friday to set up the multiplication of (3x + 2)(3x + 2). How does this answer compare to the one you got originally?
Given: 4x^2+25y^2+16x-150y+141=0 Graph and identify everything you know about this conic section.
(You will need to figure out how to show this on Google!)
Okay let me break this down Chandler’s Way. This is where Doomsday begins.
1) Given: 4x^2+25y^2+16x-150y+141=0 WOW! 2) Put the Xs with the Xs and the Ys with the Ys. SPECTACULAR! Make the 141 equal the equation: 4x^2+16x+25y^2-150=0 3)Take out 4 as the common factor in the Xs and OUTRAGEOUS! 16 as the common factor in the Ys and complete the square: 4(x^2+4x+4)+25(y^2-6y+9)=-141+(4 x 4)+(25 x 9) 4) Compact the squares and add the multiplied numbers (4 x 4) NOT PLATITUDINOUS! and (25 x 9) to -141: (4(x+2)^2)+(25(y-3)^2) =100 5) Divide everything by 100 NOT PLATITUDINOUS! ((x+2)^2/25)+((y-3)^2/4)=1 Well look at the marvelous masterpiece, it's an Ellipse! As you can see the bigger denominator always being a^2 is under the X^2 making it in the X Axis for the Focal Axis. Well using the equation for any Ellipse, ((x-h)^2/a^2)+((y-k)^2/b^2)+1, we can reflect back at this problems equation as find out: A) a^2=25, so √25=5=a SHAZAM! b^2=4, so √4=2=b c^2=√(a^2-b^2)=√(25-4)= √21=c
B) Major Axis Length: 2a=2(5)=10 DAREDEVIL! Vertices: (3,3) (-7,3)
C) Center: (-2,3) OUT OF MY MIND!
D) Minor Axis Length: 2b= 2(2)=4 LEGIT! CoVertices: (-2,5) (-2,1)
E) Foci: (-2+√21,3) (-2-√21,3) CAN WE SAY BONUS POINTS?!
F) Eccentricity: e=a/c=√21/5 INDUBITABLY!
G) The graph of the century is one click away. i warn you that it's unique. GASP!
I know, this is some crazy work here. No need to give me a gold medal
My favorite activity on Google was being challenged to solve problems that weren't the ones that we normally see. For example, my group had to solve a problem about the illumination of the moon. Even though there were parts that stressed me out because I was having difficulty solving it, the coming together of people to do the group work was fascinating. Since this group was made up of people that I would never usually talk to it was an unforgettable experience. The thing that makes it so memorable is the fact that I saw that my group was editing the document for over an hour on the night it was going to be due. This demonstrated to me that there were people in my class who were dedicated to finish solving the problem, which essentially made me feel more connected to other people in my class.
