Factor/Label Method

I wish I had seen this video when I was editing the Physical Science Module 1 post!
It is added to that post now, but I'm posting it here for those that may have missed it.  Or still need a bit more clarity on the Factor/Label method, or need a bit of review, or are just curious about this awesomely simple, but so logical video!  =)

A bit loud, so you may want to turn it down.  =)

Factoring Trinomials using the Berry Method

Before using this method, I recommend that you fully understand how to FOIL and how to factor trinomials. (See math tab for more posts about polynomials and trinomals).

24 Game - Help!

Ok, friends, I need your help!

I need:
-4 numbers, single-digit only (0-9)  ETA: oops, no zeros!
-must equal 24 by using any of the 4 operations + - x ÷
-use parentheses where needed

Examples:
1 x 2 x 3 x 4

(0 x 1) + (6 x 4) 

I want a game called "24 Game" but do NOT want to pay $22 for it! So I will make my own game on cardstock. =)
The four numbers are written in a circle that has an X across it, one number in each ¼ of the circle. Each player draws a card then figures out the order of operations to get 24.

I need as many different combinations of numbers as possible, so leave me a comment with as many as you can think of.  You can post anonymously if you like.  =)

Thanks! =)

ETA:  Combinations were given by a friend in the comments, but I didn't see any zeros, so I was wrong about that part.  Ignore it, please.  =)

A Message to my Readers

I am slowly going through all past science posts, and checking videos, adding links for images, etc.
However, I may not check every link, and a video that plays today may be removed next week by the person who uploaded it, and you will get some kind of error message when you click play.
There have been times I've posted a video, and two days later one of the kids in my class tells me it won't play.  Already.  =(

So as you view my posts throughout the year, (any posts, not just science!) if there are any unplayable videos, or broken links, or links that do not link to what they are supposed to, just leave a comment on that post and let me know.
If you see any other errors, please feel free to advise me of those as well.

Thank you so much!

Eureka!

***I have found ALL the "Eureka!" videos back on youtube!!!***

If anyone had viewed my Physical Science posts in the past year, you may have been sad to discover that none of the Eureka! videos would play, since the user deleted his account. So I am happy I found these! I will be adding these back to the posts soon, but in the meantime, all 30 can be found here.


Please comment on the channel if you appreciate the youtuber loading these videos.
