Learning Target 74:  I can solve quadratic equations using the quadratic formula.

Agenda:

1. Do Now:  Consider the quadratic function y = x² – 4x + 3.
   a.  Find the discriminant.
   b.  How many zeros does this quadratic function have?
   c.  Find the zeros using your graphing calculator.
   d.  Solve the quadratic equation using factoring (show all your thinking).
2. Notes:  Algebra Nation Section 5 Topic 9 (p. 148) – Quadratic Formula.
3. Class Work:  “Try It!” and “Beat the Test!” (p. 149).
   IAN p. 205 – Quadratic Formula Find the Error. (We’ll save this for tomorrow due to the half-day today.)
4.  Homework – Quadratic Formula Memorization Assignment (due Wednesday 6/6/18).

Learning Target 72:  I can solve quadratic equations by taking square roots.
Learning Target 73:  I can determine the number of solutions of a quadratic equation using the discriminant.

Hours 5 and 6:

►Nobody completed the prerequisites for Quiz 27 today.  Therefore, Quiz 27 is a 0% in the gradebook for everyone.

►In order to take Quiz 27 and change the 0% in the grade book, you must complete all the prerequisites, then take the quiz in records room or during lunch.

►No homework – work on your Quiz 27 and Quiz 26 prerequisites during your homework time this evening.

Quiz 27 Prerequisites:

1.  IAN pp. 203-204.
2.  Khan Academy Number of solutions of quadratic equations (with a passing score).
3.  Khan Academy Quadratics by taking square roots intro (with a passing score).
4.  Khan Academy Quadratics by taking square roots (with a passing score).

Hours 1, 2, 3:

►There was no class today.

►Quiz 27 will be combined with Quiz 28

►Please make sure you have your Quiz 27 prerequisites completed before quiz time so you will be permitted to take the quiz.

►No homework – use your homework time this evening to work on Quiz 26 and Quiz 27 prerequisites.

Learning Target 73:  I can determine the number of solutions of quadratic equations.

HOURS 5 AND 6, PLEASE DO YOUR PRACTICE HOMEWORK, AS WE STILL HAVE A QUIZ TOMORROW.

Agenda:

1. Do Now
2. Class Work – IAN pp. 203-204
3. No homework – continue preparing for your missed Quiz 26.

Tomorrow:

(In order to take Quiz 27 you must have completed IAN pp. 203-204 and the last 3 Khan Academy assignments by tomorrow at the beginning of class.)

Learning Target 73:  I can determine the number of solutions of a quadratic equation.

Agenda:

1.  Do Now (review of solving using square roots).
2.  Notes (IAN p. 202) – using the discriminant to find the number of solutions.
3.  Class Work:  Khan Academy Number of solutions of quadratic equations.

No homework – use homework time to get your make-up work done so you can take last week’s Quiz 26 (see Wednesday’s post).

Have a safe holiday weekend!

Learning Target 72:  I can solve quadratic equations by taking square roots.

Agenda:

1.  Do Now is Algebra Nation Section 5 Topic 6 (page 143).
2.  Class Work is:
   ►Beat the Test (A.N. Page 144);
   ►Khan Academy Quadratics by taking square roots intro; and
   ►Khan Academy Quadratics by taking square roots.
3. When finished with the above, work on missing assignments/quiz readiness (see yesterday’s agenda).

TURN IN YOUR ALGEBRA NATION BOOKS AT THE END OF THE HOUR.  I WILL GRADE SECTION 6 TOPIC 1, SECTION 6 TOPIC 5, SECTION 5 TOPIC 6.

Learning Target 70:  I can graph quadratic functions.
Learning Target 71:  I can solve quadratic equations using graphing.

Quiz 26

(There are no more “not yet quizzes” beginning with Quiz 26.  You must be ready to take the quiz before you take it, as there will be no second chances.)

To be ready:
►Khan Academy Parabolas Intro
►Khan Academy Graph quadratics in standard form
►Khan Academy Graph quadratics in factored form
►Khan Academy Graph quadratics in vertex form
►Khan Academy Graph parabolas in all forms
►IAN pages 199, 200, 201

QUIZ WILL BE SHOWING AS A 0% IN THE GRADE BOOK UNTIL YOU TAKE THIS QUIZ.  PLEASE TAKE IT AS SOON AS YOU ARE ABLE.

Learning Target 70:  I can graph quadratic functions.

Agenda:

1. Do Now (Algebra Nation Section 6 Topic 5)
2. Class Work:  IAN p. 201 (handout)
3. Homework:  Khan Academy
