For additional and/or previously-covered topics, please see the sidebar to the right.

It's best to start by multiplying a two digit number times a one digit number.

Next, increase the complexity by multiplying a three digit number times a one digit number.

Take the quiz for practice and to see how you're doing.

For more practice of varying difficulty, try this site.

Now you're ready for the next step, multiplying a multi-digit number by another multi-digit number. Watch the video below to see how it's done.

This site will also show you, step by step, how to multiply multi-digit numbers. You can feed the computer any numbers you want; it will then display how to do it (great for checking your work for the other sites too)!

For a real challenge, once you've got multiplication wired, try out this fishing game!

Feel free to stop by after school for clarification on what was taught, if your son or daughter is unclear on a concept.

Order of operations is an agreed upon order in which mathematicians work problems that contain more than one operation. For example, if you had a problem like: 4 + 7 x 2, would you get 22 or 18? To avoid confusion, we complete operations in the following order:

Parenthesis: any operations within parenthesis are done first.

Exponents: next, clear exponents.

Multiplication and Division: Work out any multiplication and/or division problems from left to right.

Addition and Subtraction: Finish up by working out any addition and/or subtraction operations working from left to right.

There are several ways to remember the above order. Many elementary teachers use the mnemonic: Please Excuse My Dear Aunt Sally. High school teachers tend to use the acronym: PEMDAS.

Either way, both methods can cause a little confusion as to how to deal with multiplication/division and addition/subtraction. Students tend to think that they do multiplication before division and addition before subtraction, but this is not true. In these cases, you work from left to right, clearing all the multiplication and division operations in the order they are encountered. Then you do the same for addition and subtraction.

For an explanation of how all this works: http://www.mathgoodies.com/Lessons/vol7/order_operations.html

For some conceptual practice try: http://www.funbrain.com/algebra/index.html

When you think you've got the hang of it, try the quiz.

----------

Order of operations is very useful when solving algebraic equations. You have to get the variable all by itself on one side of the equation so that you can see what it equals without any operations being done to it. For example, if you have X + 2 = 7, you can tell that when you add 2 to X, you get 7. But what if you wanted to know what X was equal to, before you added 2 to it? We can figure this out, by "undoing" what was done to it. In other words, we can subtract 2 from the left side, as long as we subtract it from the right side as well. When you subtract 2 from X + 2, you get X + 2 - 2, which just equals X. When you subtract 2 from 7 you get 5. So X = 5. If what is being done to X is more complicated than adding 2, you can undo it, by reversing the operations. If we have X x 2 + 2 = 8, we work in reverse order of operations to get X by itself. Since the last thing you'd do is add 2, we'll subtract it first. So X x 2 = 6. Now we'd undo multiplying by 2 by dividing by 2 instead. So X = 3.

Check here for a demonstration of how to solve one step equations.

If the idea of getting the variable by itself doesn't make sense, use this pan balance to see how it works.

Embed a calendar into the events page (start with SUSD cal possible?) Ok, foget the embedding. I'm just going to use the Zimbra calendar. Shared it with the grade lvl- that way we all can add dates, not just me. It's public viewable and the url is linked (now if only Zimbra would let me add appointments...hmm

Try to find a consistent way to link back from blogs to wiki (can banner be linked in the stylesheet?) ...added a clickable banner to my stylesheet...used firebug (a firefox plugin) to figure it out. I think most people would find it easier to just add a link somewhere on their sidebar.

Add links to curriculum standards under each area...done. I also did a little comparison of 5th and 6th grade standards since I'm doing a split. This was mainly to get my focus laser-tight on the differences that I need to plan for but I think my parents will appreciate that I appreciate those differences.

Podcast page for podcasts or tied to curriculum? So far, they've been in blogs but a library of 'em would be nice...I think putting these in context of class notes makes them more useful.

Help desk would be a static page for people to ask questions and get (not as timely as they'd like) answers. Maybe there's an Open Source whiteboard that could be configured for logged in users only...Still not too much going on here. I think I'll just put my phone-podcasting service player in there. I could call with important info- like if I noticed a problem with homework or something. Parents/students would have to know to look there first before calling me.

Separate page off of resources for educators for training resources...blah- Delicious links are good enough

Concatenate links from all over the place into the educator's resources page :yawn ...see above comment

Ask Jim why font size doesn't seem to work (browser issue?) and how the fullscreen edit works (no save on popup window) ...seems to be working now. Must hit "update" button. Now if I could only figure out why my Firefox doesn't seem to play Java-based apps despite having the plug-in.

Cool widgets... ...can't seem to get any widgets working. I don't think too many are supported by the implimentation so far. Still, maybe I'll link in some teachertube stuff and slideshares. I know at least those work from having tried it out with the blogs

Make a wii smartboard and see if someone has ported the software to mac yet...Done. Works well, but setting the remote up and calibrating it each day may be more trouble than it's worth.

Change everything over to 4th grade...done. But update the info for current class goals.

Change hierarchy of pages so that the built in nav bar is less jumbled.
