It is so unfortunate that the emphasis on the commutative and associative properties so often boils down to which property is being illustrated, versus what is being illustrated. That’s why I wanted to introduce this topic by having students add a string of integers that consisted of pairs that summed to 10. In that case, they naturally use both properties to rearrange the sum to make it easier.
The lesson: CCAlgI.Unit #1.Lesson #3.The Commutative and Associative Properties
So, the answer keys arrived yesterday. We printed an original run of 60 CDs and will run out of these quickly. Each CD contains the entire text, in both pdf and Word format, and the entire answer key, in both pdf and Word format. They can be copied to any district owned computer and any computer owned by a teacher in the district. Expect to see them arriving this coming week. Thank you everyone who ordered. Remember, books may not be there until the last week of August and if your business office is slow getting us the PO, you may not get them until the first week of school. Email me if you want to know if yours were ordered in the “first wave.”
Update: We shipped all answer key orders this morning!!! The Rhinebeck post office was a bit overwhelmed, but Mark at the desk was a trooper and processed all 35 orders. The expected delivery date for all locations in New York is Monday, August 18th. So, look for them soon. They will come in a small bubble wrap package. There will be two identical answer key discs. Email me if you have any questions about order status.

Hey All,
Well, we placed the first round of PO orders that we’ve received to our printers yesterday. They are quickly creating the CD’s that have the answer key and text on them (both in pdf and in Word). So, those will probably be shipped out in the middle of next week. The workbooks will be heading out by the end of next week and will arrive in the last week of August. Sorry they couldn’t be there sooner.
Warning: Any PO for workbooks that I receive from now until the end of August will most likely not get there until after Labor Day weekend. Be prepared to photocopy the first few lessons from this website or our original emathinstruction site. Check with your business offices or send me an email to check. Orders of only the answer key will still get to you before Labor Day even if they arrive in the coming weeks.
On the browser issue. I continue to find that Chrome does not work well in terms of either this site or the original site. I just downloaded the most recent version of Firefox and it works great for both seeing this site, downloading files from it, and downloading from the original site. Internet Explorer has worked well for both all along.
Take care and continue to enjoy summer. Kirk
Well, the school year starts for many of us right after Labor Day weekend, less than three weeks away. For some, it starts even sooner. In anticipation of that, I’m making freely available the answer key compilation for Unit #1. You can download it by clicking on:
I hope this helps planning for the upcoming year easier. It’s never too late to start commenting. I won’t start making edits until it makes sense to make edits, i.e. as the year progresses and we see where this experiment leads us.
For now, download some Unit #1, get some photocopying done, and don’t forget to hit the Dutchess County Fair with your kids! It’s awesome.
Hey Friends of eMathInstruction. I’m trying to find the best platform for teachers to share thoughts about the lessons in the curriculum. I’m experimenting with this new website on WordPress and think it has great possibilities. Ben Kirk, a math teacher at Ithaca High, gave me this suggestion and I wanted to thank him for it. Hopefully I will use it to its best ability. Right now I am setting up discussion topics by Unit so that people can post comments about individual lessons within the units. I’ll be spending time in August trying to come up with the most efficient system. If you have any thoughts or experience with WordPress, please consider replying to this post to give me advice.
O.k. So, this lesson is mainly about expressions and not so much about variables. At this point, I make the assumption that students are comfortable representing unknown quantities with variables, so not a lot of discussion occurs with them. Leave your thoughts and comments, please!
Hey all. I’m new to this blogging thing, so please excuse early hiccups and whatnot. I’m posting the first lesson here along with the YouTube video, I think. I’m hopeful that this then will give people a chance to comment on either, or both. Let’s see what happens.

Hey Common Core Algebra I teachers. If you have any thoughts about assessments of any type, please consider sharing with others through this category.
So, this is my first blog post on our new discussion site. Many of you will be using the Common Core Algebra I curriculum this year that I wrote over many nights in the winter of 2013-2014. It is an imperfect text, and always will be. But, it can be made better through lesson study, comments, suggestions, and sharing. I believe that we can make a successful transition to the Common Core at the high school level with the input from practitioners around New York State and the country. I hope that you will join me in finding ways to build a better Common Core Algebra course.
