Collaborative Inquiry
❏ Uses Socratic questioning
❏ Utilizes resources to investigate
student presenter’s POC
❏ Takes focused notes (Phase 1) or
supplements academic class
notes (Phases 2-3)
Communication
❏ Communicates clearly, both
verbally and non-verbally
❏ Listens effectively to decipher
meaning
❏ Demonstrates command of
academic vocabulary
❏ Adapts speech to an academic
setting
Reflection
❏ Summarizes key
academic learning points
❏ Reflects on today’s
tutorial process and
identifies next steps
Topic/Essential Question from Academic Class:
Focus and Directrix
Initial Question:
Rewrite the equation in vertex form. Then find the vertex, focus, directrix, axis of symmetry, direction of opening,
and y-intercept.

Key Academic Vocabulary and Definition Associated with Topic/Question:
1.
Directrix- A y= line that does not touch the parabola. The parabola is halfway between
this and the focus.
2. Focal length- The distance from focus to parabola.
What I Know About My Question:
/4
1. The vertex form equation can also be shown as y=1/4c(x-h)^2+k.
2. The ‘c’ value is the distance from the focus to the parabola.
3. The focus is a point that the parabola faces and a directrix is a line that the parabola never touches.

Critical Thinking About Initial Question with Corresponding Steps:
Use these symbols in the Critical Thinking box and on the board to identify the following:
❕= A-Ha! moments ❔
= Point of Confusion �= Need to research �= I’m confident about…
1. Show your thinking about your initial question, and identify your Point of Confusion.

y=x^2+4x+1
Vertex form- (a is the same) (x=-b/2a) (y=a(x-h)^2+k)
Vertex- (h,k)
Focus- (y=1/4c(x-h)^2+k)
DirectrixAOSY-intercept- (0,1)
2. List the general steps that you took leading up to your Point of Confusion.

Tutorial Question (from Point of Confusion):
Write an authentic question about your Point of Confusion that is different from your initial question.

Eliminate the prepositional clauses
and relative clauses to find the
main clause of each sentence.
Prepositional clause- A
prepositional phrase is a group of
words consisting of a preposition,
its object, and any words that
modify the object

How do I use my knowledge of
focus and directrix from 5-4 to
apply it to 5-7, to solve my
problem?
Directrix: -3.25
Focus: (-2,-2.75)
a=1/4c
Reflection- I learned that I can find my focus from a from my equation using the equation a=1/4c. When I put in 1
for ‘a’, I got c=¼. This helped me find my focus of (-2, -2.75) and my directrix of -3.25, because I know how c
corresponds to both.
