### Math Minute

Back in September, I decided to try a new way of sharing some of the cool stuff I hear about online with the math department at my school. I call it "Math Minute" and this is part of the original email I sent them:

"Hello fellow mathies,

I thought I would share some of the great things I come across on Twitter and on the blogs I read. It might be a cool activity or link to an article or blog post, but should only take a minute (or so) to read - hence the Math Minute title. I'll do my best to send a Math Minute out once a week, however please feel free to let me know if you would prefer not to receive them."

This was followed by a short description and the first link that was all about Desmos card sorts.

Here is the link to the Google doc I am using to keep track of what I have shared.

This is a sample (since it had no link):
"Week #8:

I have been using the box (area model) method for multiplying and dividing polynomials for a while now. I like it because there are no tricks involved and students can see (and hopefully understand!) why they are doing what they are doing.

Below is a sample of factoring a non-monic trinomials. There would normally only be one box, but I tried to make my steps understandable for you. I have to say that I love algebra and decomposition and I have been friends for a long time, but I love the box for these. Try it out!

Cheers,

Mary"

Although I have had little feedback from these Math Minutes <insert sad face>, I thought I would share what I've done in case someone else is looking for a way of sharing ideas.

1. Cool idea. Great way to give PD to fellow teachers!

2. Excellente idée! Une belle façon d'encourager et d'inciter sans mettre de pression! :)

3. I LOVE this! I'll forward tweets to people and send links of blogs, but I love how you named it! I also love the box (or generic rectangle) method! CPM teaches binomial multiplication using the generic rectangle so I can't wait until we factor...it just makes so much sense. Thank you for sharing this with us :)
