Thursday:  Test over Functions has been rescheduled for Monday and Tuesday of next week.

Friday:  Test over Functions will be Monday and Tuesday of next week.  Students should go back over the problems that they missed on the quiz.  We spend Wednesday and Thursday working problems and discussing error analysis.  Students continue to make many careless errors which include errors with distributive property, trying to reduce when their is no common factor, failing to use formulas when beginning problems. . .I often times put links on the blog that will be beneficial to the students if they choose to view them.  It will also be beneficial for the students to look over any examples in their book that relate to the standards being taught.

TUESDAY - FRIDAY:  Trig Ratios - We will work on learning the trig ratios (sine, cosine and tangent) by identifying the opposite and adjacents sides of a triangle with respect to a given angle. The students will begin their study of trig ratios by completing a task in which they will do some discovery learning.  We will end the week by summarizing what they should have learned and solidifying the concepts by working through specific examples. The students will have an opportunity to prove what they have learned by practicing problems.

TUESDAY'S HOMEWORK:  Parts one and two of the task. . .

WEDNESDAY'S HOMEWORK:  Parts three and four of the task. . . 

THURDAY'S HOMEWORK:

FRIDAY'S HOMEWORK:

MONDAY:  Today we continued our study of Special Right Triangles.  I glanced over the student's work from Friday and noted that many of them didn't draw and label their diagrams.  I also noticed that many of them didn't start the problem by stating a formula.  I am trying to teach them proper procedure in solving right triangles as opposed to just multiplying or dividing things in their head.  Their work should flow algebraically in order for them to retain what they are actually learning.  I have stressed to them the importance of showing enough steps so that if I pick up their paper, I shouldn't have to revert back to the book to understand what they are trying to accomplish on their paper. . . I took up the quilt task and asked the students to correct Friday's assignment.

Homework: Page 155 #1-12 (Copy and label diagrams, begin with proper formula and show all work algebraically).

 

MM2G1a - Determine the lengths of sides of 30-60-90 triangles.

MM2G1b - Determine the lengths of sides of 45-45-90 triangles.

Students should attempt the homework problems as we covered concepts needed to complete the assignment in class on Tuesday. First period can read section 1.5 to distinguish the difference between rigid and non-rigid transformations.  I placed quite a few links on the blog yesterday for students who may need some additional information. . .  Please look at these if you are needing additional help/insight with the standards.

Homework check will be done on Thursday due to the fact that first period didn't meet today and second period was cut short.  In an effort to maximize class time during second period, I postponed the homework check until tomorrow.

Math II (September 21 - 25)

Note to Parents/Students:  I found two mistakes on the key for "The Great Quadratic Test".  These were corrected in 6th and 7th periods but not in 5th period.  Please bring your test to class with you on Monday if you are in 5th period and we will go over these two corrections and I will update grades. 

Standards for the Week:

MM2G1a - Determine the lengths of sides of 30-60-90 triangles.

MM2G1b - Determine the lengths of sides of 45-45-90 triangles.

Friday - Today we will begin our Unit on Right Triangle Trig by discussing Special Right Triangles (30-60-90 and 45-45-90).  I will give the students formulas but I will also make sure that they understand how to use pythagorean theorem to arrive at the answers.  Please understand that using formulas are much more efficient and timely most times than having to figure everything out from scratch but the students do need to understand where the formulas came from.  FORMULAS are not given to students for tests.  Although it isn't necessary that they memorize them to be successful, it will allow them to make more efficient use of the time they are allowed in which to complete their assessments. Draw pictures, Label sides, write formulas and show all work when working problems.

Homework:  Page 153 #1-9 and Page 154 #14-19

Thursday - We went over the first page of the quilt task today.  Students should have learned that in a 45-45-90 triange, the hypotenuse is equal to the square root of two times the leg.  Please ask them to explain this to you.  Also ask them where this formula comes from. Students got their tests back and we will go over answers tomorrow.

Homework:  Quilt Task (2nd Page Front and Back)  

Tuesday - Wednesday (NO SCHOOL DUE TO FLOODING IN THE AREA)

Monday - Quilt Task

AAT (September 14 - 18)

NOTE TO PARENTS:  I have graded the first page of the assessment from yesterday.  In looking over the tests, I am finding that when students show each step of their work, they avoid most caresless errors.  When students get in a hurry and try to save time (and room on their paper), they end up making many careless errors.  If I can find their mistakes, because they have shown steps, often times I can give them the partial credit that is deserved for their correct work.  If I have to guess what they were doing because the work is not actually on their paper, I can't give them credit for what I think they were trying to do.  I also want to stress the importance of the homework packet.  If there are any problems that the students didn't complete, those problems may very well be the ones that they needed to understand for the test.  They have ample time between the announcement of assignments and due dates to seek any extra help that is needed.  I consistently forfeit my lunch period and my planning period to help  students who request one on one instruction to improve on their mastery of the standards.  If your students is struggling with this class, please encourage them to come in for extra help.  They should bring questions regarding specific homework problems so that we may make the best use of our time.  I am also available each day after school and mornings from 7:45ish - 8:15. Please do not hesitate to contact me as I welcome correspondence from parents regarding students.

Friday - I gave back the chapter 2 tests today.  The students have a couple of different things to work on this weekend.  They received a worksheet in which they are to state the domain and range of given graphs using interval notation.  They should also continue working on section 1.2 pages 100 and 102.  I postponed beginning section 1.4 today so the assignment that was listed for today on the board will not be assigned until next Tuesday.  This will give me time to answer questions over the homework from page 102 on Monday.  We will dedicate the class period for that purpose on Monday.  BRING QUESTIONS TO CLASS. . .

Thursday - Today we will continue section 1.3 while looking at real world applications involving functions.  We will also go over the distance quotient.

SOLUTIONS:  Download Chapter 2 Worksheet Solutions

Math II (September 8 - 11)

Friday - We didn't get to go over the worksheet from Thursday in 6th period.  We will do this Monday.  We covered intervals of increase/decrease and rates of change over given intervals.

Homework:  Page 72 #5-13.

Thursday - Students should complete any errors on the worksheet from last night.  We went over these concepts in class again today.  We also reviewed graphing concepts (finding roots,vertex, y-intercepts, equation for the axis of symmetry, factored form of an equation, quadratic formula, and vertex form of an equation. 

Homework:  Finish page 3-4 of the calculator investigation. . .

Wednesday - Today we will look at converting quadratic equations from standard form to vertex form (use x = -b/2a to find the x-coordinate of the vertex and then substitute the x coordinate into the original equation to find the y-coordinate of the vertex). We will also convert equations from vertex form to standard form (multiply and simplify - ask your student to explain).    I am including some helpful links for the students to view.  Completing the square is a concept that will be taught in Math III but it is included in some of the links as an alternate method of converting equation from standard form to vertex form.  It is not necessary to learn completing the square in order to do the conversions if the students understand how to use x = -b/2a to find the vertex. . .Some of the examples in their book do show completing the square so I have included some examples in the links below. . .

Homework:  Worksheet 3.2 and 3.7

• http://www.mathwarehouse.com/geometry/parabola/standard-to-vertex-form.php (Pay attention to the links within this site.)
• http://www.nipissingu.ca/calculus/tutorials/quadratics.html (Completing the square and other concepts we've covered in class.
• http://www.youtube.com/watch?v=z3vMeBv-wtg (video)

Tuesday - Today we went over answers to the Unit I Part I Test.  The students weren't told this because I realized it during 7th period:  I took the grade out of 108 and it should have been out of 112.  Everyone will have 4 points added to the original grade.  If the students did poorly, they know that if they do better on the Unit I test which includes the Part I standards again, I will replace the first test grade.  They need to seek help with any unmastered standards. . .We covered Standard form of a quadratic equation, finding the vertex, the y-intercept, x- intercepts, domain, and range of a quadratic function in order to graph them.

Homework:  Page 58 #5-21 odd
