Welcome to Mr. Long’s Math Blog

August 15th, 2014

I use this blog to post lesson plans and homework for my Math Options, Math-2 (honors) and Math-3 (honors) classes.

Since every entry I make in this blog (about 800 by the end of the year) will show up in the center of the screen, with older entries pushed downward and the newest entry at the top, THE BEST WAY TO FIND SOMETHING is to go the CATEGORIES on the right side of the blog.  Clicking on one of the category buttons will “filter” the entries in the center of the blog to only those that pertain to that category.  You might have to scroll down a little bit within that category to find what you’re looking for.

I will cover the posted lesson plan in class.  I usually post the lesson plan and the homework for the lesson plan after it is taught.  I will do my best to get the lesson plan and homework posted by 3 PM the day it is taught.

You DO NOT NEED TO PRINT OUT HOMEWORK!  You can work off of the screen onto a separate sheet of paper.

Please see RULES AND PROCEDURES for my disclosure statement.  You can either print out the acknowledgement form or you can handwrite one out.

At the BOTTOM RIGHT side you will find some useful tools: a couple of online graphing calculators and some links to math websites.

I hope that enjoy the class!

Math-2 Lesson 5-2 (notes and homework)

November 24th, 2014

If you did not finish Lesson 5-2 in class, it is now homework, I gave a copy of it in class to finish.

If you do not have a TI-83/84 graphing calculator at home, there are two different calculators on the bottom right side of my blog. You can use these.

This lesson learning by group work (with leading questions by me to keep your thinking on track). You should have taken your own notes. If you missed class, you’ll have to work through it on your own to figure out what we learned. Once you’ve done that, please come see me and I will help you with any questions you may have.

The key point here is the difference between a quantity (“what” is being measured: height, weight, length, temperature, volume, area, etc.) and a unit of measure (“how” the quantity is measured: feet, miles, square inches, degrees Fahrenheit, cubic miles, etc).

Units can be “cancelled” using the inverse property of multiplication just like variables can be cancelled. They can also be multiplied, added, divided, etc. So 2 ft times 4 ft = 8 ft squared.

Unit conversions use the identity property of multiplication (“any number times 1 equals the same number”). When we convert units we multiply the measure of a quantity by a ratio of units that are equivalent (multiplying by “1″). Then you just simplify the units (“cancel” units using the inverse property of multiplication).
