Gallery walk

Do not forget that your district assessment is Tuesday of next week. On Monday please bring a signed note indicating that you have studied. You also need to bring your Post test paper back on Monday. Please review the links pertaining to rational numbers, Pythagorean theorem, and scientific notation.



Remember that you may also sign up for our podcast and receive our video lessons.

Checkpoint tomorrow

The following video explains some questions that relate to your checkpoint tomorrow.




Below you will find a copy of the questions that are explained in the video.

Answers to our last test

Most periods did well on the test, however there were some popular mistakes. These mistakes are discussed in the video below. Also, do not forget that everything that we will do for the year is shown on the podcast and on our class wiki.

You may explore topics like scientific notation and pythagorean theorem on the wiki.

On each of those pages there are example TAKS problems, but there is also a separate page dealing with the TAKS test

Assessment tomorrow

Do not forget that you must have a study note signed by your parent when you take your assessment tomorrow. Also, please practice the concepts that we have discussed so far. I have posted a practice test in the box.net sidebar on the lower right side of your screen to help you practice your concepts for the test. Also, I have included a copy of it below.

More on scientific notation

There are many ways to convert numbers from scientific notation to standard form. You could estimate the product and use that to verify your answer. For example 2.08 x 10^2 is close to 2 x 10^2. Since 2 x 10^2 is 200, you know that the answer to 2.08 x 10^2 is close to 200. So the answer is 208. Or you could move the decimal point according to the power of 10 that you have. If you have 3.16 x 10^3 you could move the decimal point three spaces to the right from where it is in 3.16. When you do that you end up with 3160.


The homework tonight is pg. 132 numbers 12-30 even.
Grades are exported Friday, please redo your study island assignment so that you can receive a higher grade. Also, please return the progress report that I handed out to you today. Make sure that it is signed by your parent. Also, test tomorrow.


If you do not have access to the textbook you may use the code (please see me) when you click the following link.

The following video is a student explaining one of the above ways to convert numbers from scientific notation.





The bottom of the paper was not visible in the video. But here is the paper that she was working on:

Recognizing a number that is in scientific notation

A number in scientific notation has the following requirements. One of the factors (usually the first number) is between 1 and 10. This number may be one but it may not be over 10. The other factor is a power of 10. The exponent may be any integer.

For example 9.7 x 10^5 is correct scientific notation, but 97 x 10^4 is not.


Homework tonight is pg. 132 numbers 11-29 (odd) and numbers 30-34, 36-44.

Also, don't forget grades for this progress report get exported this friday. You must also complete another study island assignment before friday at 5 p.m.

How can you write numbers in scientific notation?

Remember that positive exponents are for whole numbers and negative exponents give decimals less than 1. Also, the first number in your scientific notation is more than one but less than 10.
