for practice and play  

Here are the answers to your final exam. Wasn't it too easy? ;)

You can use this review powerpoint to study for your semester exam, which is on Monday, June 1st

Play with the Interactive Slope of Line page to get a feel for the measurement of slope.

As we start work on Functions, you can play with these sites: Whole Number Cruncher function machine

And this link is for the Number Cruncher function machine (includes negative integers)

For Earth Day, we will make Tessellations. First we can make some very simple tessellations here.

You can make these very fancy if you wish. Look at this explanation.

Then we can move on to making tessellations where the orientation of the shapes can change. Many artists use this technique with much more intricate shapes than simple polygons.

You can try this yourself on the shmuzzle web page

One of the most famous artists who used this technique was M.C. Escher, and we can see some of his work on-line.

You can scroll through one of his most famous pictures here.

We will make some slightly less intricate shapes for our own tessellations, using a technique similar to this one. We can try something like this on-line to see the effect.

We have been studying the Pythagorean theorem. Click here to see the animation with the squares on the hypotenuse, and you can also see the animated proof here.

In class, we looked at the shapes of various buildings. and you built a structure from 3D blocks that included cylinders, cones and pyramids as well as cubes. You then had to draw a massing sketch of this structure - you can look here to find examples. You can get some help with 3-D drawing here, and with isometric drawing (another way of making 3-D drawings) here. You can print out isometric dot paper if you want.
Assignment: Imagine a use for your building and produce an illustrated essay, a brochure or a graphic essay (comic) to describe the building and its use for prospective investors. Relate its structure and shape to its function. This will be due Monday, April 26th.

Massing sketch - 10 points
Illustrations - 10 points
Written discussion - 20 points
Appearance neat and attractive - 10 points

We need to learn the names of various kinds of angles formed by a transversal crossing a parallel line. Here you can see that corresponding angles and alternate angles are equal. You can also go to a web page to help you with your vocabulary. This is another vocab site, but it also has a cool applet showing how to use a protractor. I especially like this page that explains how to use a protractor, which I showed you in class. Here is another amazing site where you can actually practice drawing and measuring angles.

We will be starting the skyscraper project on Monday 2/1. You can see the instructions and rubric, and also the data sheets, including the sheet for the Transamerica Pyramid, which I didn't have this morning. This project is due no later than Wednesday 2/3.

You can study for the semester exam by trying the worked practice problems at th end of each chapter that we have covered in the textbook. You can also go over the powerpoints Semester Review 1 and Semester Review 2.

I use "Chasing Vermeer" by Blue Balliett as an introduction to a unit that I call "All Math Bright and Beautiful". Your first assignment was to decode the 4 coded letters in the book (past due now), and here is your second assignment, which is due Monday, 25th January. You can find an amazing amount of information about Vermeer and his paintings at the Essential Vermeer web site

You need to do the Data Display project. The data set is here ; the due date is December 18th.

You can watch the Powers of 10 tutorial - remember to look for the power of 10 magnification in the bottom left-hand corner of the picture.

To practice fraction multiplication, try these problems. If you hold your mouse over the answer, the answer will be shown, so do the problems first, then you can check whether you are correct. Once we have covered division, you can do these division practice problems.

Here is theChapter 4 Study Guide.

You can watch the Powers of 10 tutorial - remember to look for the power of 10 magnification in the bottom left-hand corner of the picture.

This is a similar site - it's better because it shows the power and the number side by side

Practice your scientific notation conversions! If you are still confused, there is a great explanation here at purplemath

You have to do a Half-Life lab to learn more about mow powers work. Here is the applet I showed you in class to explain what half-life means. Finish the lab (on p. 180 in your textbook) for homework.
Your data is:
1 half-life: 189
2 half-lives: 101
3 half-lives: 51
4 half-lives: 29
5 half-lives: 15

Here are the answers to FCAT pages 18-28. Remember, if you haven't done it yet, you are on your honor not to look. Do it and turn it in for partial credit.

On Friday, we will try to play the Algebra Four Game. You will need a partner, a pencil and a piece of paper. When you start the game, make sure to click the 'Distributive Property' and the 'One-Step Problem' boxes - it will still be very challenging!

This Algebra Balance game is fun to play when solving equations, but it may be a little less simple than the problems we are doing this week. This version includes negative integers.

To work on Integer Addition, use this Color Chips Addition applet; then you can move on to the Color Chips Subtraction applet. Make sure that you know and understand the Integer Rules

Interactivate has a site where you can plug in data points, and make a scatter plot!

Here is the Excel file with the data for your scatter plot, about height and arm span.

To start off, here is a good game to practice Order of Operations

The summary of the week's homework is here.

Welcome to 6th grade Pre-IB Pre-Algebra.

This will be a fascinating year as you start to study real math, but be warned, you will have to work hard. You will also be doing quite a bit of reading and writing for me! Don't forget to do your service hours (4 hours per grading period), and turn the signed forms in to me.

As we go through the Pre-Algebra Curriculum, I will post links that will help you with the topics we are covering in class.


There's more on the way!
