Reminder To All Classes

Don't forget to collect your supply list.  Please have your parents initial by all the materials you have acquired and turn in the list when it is complete.

I didn't set a deadline for having supplies but try to have the list completed by August 25/26.

Parents if you have any questions please send me an email by following the link.

M3 CS

The quiz on Thursday and Friday will be very short.  All the classes seem to be in different places for various reasons.

By now you should be able to write the nth term of an arithmetic and a geometric sequence and find the given term such as a15 or a50.

The homework sheet is good practice for these skills.  Make sure you complete those problems--you need the practice!

Algebra

I am working on grading your tests.  One of the things I am noticing is that many of you are having great difficulty with subtraction.

(4x+2) - (6x - 8)  MEANS 4x + 2 - 6x -(-8) or 4x + 2 - 6x + 8 

Combine your like terms to get -2x + 10.

Remember subtract means add the opposite!

Algebra Support

Today we practiced simplifying radicals.

Next time make sure you have studied your perfect square flash cards because there will be a short quiz!

 

Algebra support

We practiced today with multiplying and the binomial theorem.

M3CS

Test on Friday 11/4 and Monday 11/7

It will cover factoring, quadratic formula, square root method and absolute value eqs and inequalities.

The review sheets are posted here.  You should make sure you can do the ODD problems on each one.Download Absolute Value Inequalities

GPS Algebra

Today we practiced multiplying polynomials.  Which method did you prefer--the boxes or FOIL method?

Can you always use the FOIL method?  What property is really being used when you multiply two polynomials together?

Tuesday is the benchmark test.

M3 CS

Today you should have finished your task on the quadratic formula and the discriminant. 

What does the graph of a quadratic look like when the discriminant is 0?  How many unique solutions does the quadratic have?

What about when the discriminant is positive? 

When are the solutions complex (imaginary)?  How many imaginary solutions do you get?

M3 CS

Today we finished with factoring.  We were supposed to move on to solving polynomials using the quadratic formula but the best laid plans of mice and men...

Quiz results were mixed at best.  1st period is posted but I made a mechanical error so 4th will take another day. 

Next time...quadratic formula a QUICK look at the square root method and then it's on to solving absolute value functions where we will end the algebra portion of the course (sort of--there's always some algebra to be done in geometry and statistics).

You all did an AMAZING job on your puzzles.  I hope you carry those skills of adding/subtracting polynomials and multiplying monomials back to your algebra classes.

Don't forget--finding the perimeter is the same as adding/subtracting.  You are combining like terms.  Area problems can be more complex.  The warm up problem was just a monomial x a monomial.

What do you think happens when you multiply a binomial x a binomial?

M3 CS

Today we finished factoring when a <> 1 

You should be able to factor 6x^2+23x+20 without too much difficulty.  If you are having trouble then I should see you in tutoring.

Finish your quadratic formula/discriminant task for homework.  This is a major grade so DON'T lose it please!  Due on 10/26
