Computer Labs

We will start our deductive geometry unit with an exploration using GeoGebra (a free geometry/algebra program that you can download for use at home).  Here is the schedule:

Wednesday, 12/19  A-Block in room 700,  F-Block has their test
Thursday, 12/20  both classes meet in room 816, we use the laptop cart
Friday, 12/21  F-Block in room 700

This should be a fun way to head into vacation but don't forget that you are supposed to learn something!

Answer Key for the Review

Here is the answer key for the Transformation and Coordinate Geometry Review.

Thursday, December 13, 2012

Studying for the big Unit Test

The test on Tuesday puts together the function transformation material with the coordinate geometry material.  It is a lot to put together and I have trying to help you see that it is all interconnected so that you do not have to memorize lots and lots of things.  Below are some hints about studying:


I have given you a Review sheet which lists the concepts and skills that you need to be able to do.  Make sure you find the test and quiz questions that relate to every concept and skill so that you can self assess which skills you understand well and which you could use more help with.

I have given you a packet of review problems.  Use them to test how well you feel able to do problems without looking at notes or getting help.

Here is the answer key to the Pairs Coordinate Geometry assessment.  Use it to help you understand any problems that you may have gotten wrong, or what you could have done better if you did not get full credit.

Don't just read over notes and problems - Do Them!  Practice is the best way to study for a math test!

Putting together Coordinates and Transformations

The last part of this unit (before the big test) is dealing with transformations of figures through their coordinates. This is not a long unit because we have dealt with many of these ideas separately already but we will be adding rotations. We will be using a packet though it is from the same book series. As always, any classwork not finished in class becomes part of the homework.

Note that the dates are for A-Block. F-Block is one day later after Mondays.

Finishing up the Coordinate Geometry Unit

The rest of the unit will be done with worksheets so the homework every night is to finish the worksheet started in class.

11/26  Recap of coordinate work so far
11/27  Coordinate Proofs - Day 1 (numerical proofs)
11/28  Coordinate Proofs - Day 2 (general proofs)
11/29  Coordinate Proofs - Day 3 (mix of numerical and general proofs)

12/03  Review of Unit (answer key)
12/04  Individual Assessment (A-Block)
12/05  Group Assessment (A-Block)  Individual Assessment (F-Block)
12/06  Group Assessment (F-Block)  start the next section (A-Block)

After this we will be going on to transformations from a geometric perspective (putting together the transformations of functions with the coordinate work that we have been doing).

Excellent description from quiz

I am going to post excellent responses to the question of the relationship between the Distance Formula, the Pythagorean Theorem and the Equation of a Circle:

"The Distance Formula is actually the Pythagorean Theorem unsquared.  Instead of d^2 (c^2) it's just d and (x1-x2)^2 and (y1-y2)^2 are a^2 and b^2.  The equation of a circle is the Pythagorean Theorem.  (x - h)^2 is a^2 and (y - k)^2 is b^2, while the radius  squared is c^2."

"They are all in some way forms of the Pythagorean Theorem, and they can all be used to find the distance between two points on a graph."

"They all tell the distance of something.  The Distance formula tells the distance of point A to point B.  The Pythagorean theorem tells the length or distance of side C. And the equation of a circle calculates the distance of points from the center of the circle."

Good one for the the Pythagorean Theorem - Distance formula link:
"The distance formula is related to the Pythagorean Theorem because they both find distance.  The distance formula uses coordinates and the Pythagorean Theorem uses already known lengths, which can all be found by using coordinates."

Good one for the Distance Formula - Circle Equation link:
The equation of a circle is the distance formula, just after squaring both sides to make it d^2 = (x1-x2)^2 + (y1-y2)^2.  This is because when you are graphing a circle, the point it is centered around, or (h, k), is the same as (x2, y2).  Also, the radius (r^2) is just the distance from the center of the circle to any point on the circle.

And best of all...
"The distance formula is like the pythagorean theorem because finding the distance between two points is the same as finding the hypotenuse of a triangle if the two points were the legs of the triangle.  It is related to the equation of a circle because in a circle you are finding points at a certain distance away from the middle."

Think about your answer.  How does it compare for completeness and clarity?

Last day of stats on the computers

Today is our last day of the statistics unit.  You will work with a partner and a computer to process two data sets that are in the file below.  The tasks are outlined in the file.  You should print out your results or email them to me (dhaupt@sch.ci.lexington.ma.us) when you are done.  You should finish before the end of the block to show that you are ready for Monday's test.

File of data (runs Excel).

The Extra Practice Worksheet - some notes

On the side that covers lessons 2.2 and 2.3 (see the top right of the worksheet)
Problem 2: Make sure  you can do parts b and c, don't worry so much about parts a and d.
Problem 3: You don't need to find the target, just the domain and range.
Problem 5: You will need to use your calculator for parts of this.
Problem 7: This one can be confusing if you don't use enough parentheses.
Problem 8: The parentheses in parts c and d indicate which composition to do first.  Try it.

On the side that covers lesson 2.4
Problem 3: You can skip this one.
Problem 8: Remember that an inverse function undoes the original function.  If you do one right after the other then you get back to where you started (ex. dollars to Euros to dollars).  Also remember that if you know that the input of the inverse is 10 then you know the output of the original function is 10 (and vice versa).

The test for A-Block has moved to Tuesday, September 25th.  The test for F-Block has moved to Friday, September 28th.

Please make sure you can log in to the book online by Monday.

Getting Started

Our first two days were spent looking at patterns and the expressions we can use to count aspects of them.  It was a different way of integrating a diagram and an algebraic expression than you may have seen before.  Hopefully it also woke up your math brain a bit.

The next two days will be spent working on an Algebra 1 Review packet.  The packet is based on the Math 1 book so you will get a taste for the way questions are asked in the new books.  Do problems 1 - 11 the first day, 12 - 23 on the second day.

Welcome!

Welcome to my blog for this new course at the High School. Math 2 will teach you to approach topics more like a mathematician - using all that you know, whether it be from the algebraic world of math or the geometric world. You will also learn what you can do when problems are so challenging that you are not sure you can solve them.  (Hint: you can always do something!)

This blog will provide you with a syllabus and homework.  Maybe suggestion too. ;-)

It is going to be an exciting year: new school, new books (that are online - no lugging it around), new friends, new challenges.  Make sure you keep up!  Remember, I am here to help you.  Just ask me.
