What are chemistry students prone to when learning stoichiometry?

Image
A blog I am reading every week is Math Equals Love . Sarah Carter , math and chemistry teacher in Oklahoma, writes in exquisite detail about the things she is trying in her classroom. Every time I read it, I wish she had been one of my math teachers. Sarah loves, and often features, puzzle she is using in her classroom. I, too, love puzzles and that's probably one of the reasons I love her blog. One of the things I loved best about middle school math were those cheesy, punny puzzles when solving a math problem led to a letter that led to an answer to a question involving math. I recently had to miss three days in my classroom, right as my students needed to take a big quiz over stoichiometry (the math of chemical reactions, for non-chemistry teachers), so, inspired by Sarah and middle school math, I created a puzzle for them to do in my absence. The puzzle consists of 24 paper tiles that have a letter in the center. All the tiles also have an answer at the top of the tile. Some o...

New Year, New Calendar

Image
Are you seeing this pop-up on your Google Calendar? Have you noticed the blue Use New Calendar button in the upper right hand corner? This week I made a screencast to highlight some of the changes in calendar: The new version of calendar has more white space, so it's easier on the eyes. The dates - the part that we are looking for on a calendar - are larger, more prominent. It has a fresh look. When you look at events on the calendar, you can see how you have RSVP'ed. Solid color event = I am attending! Solid color event with diagonal lines = Maybe I am attending. Outlined event = I have not responded to the invite.  Outlined and struck through text on event = I am not attending. When you add an event or edit an event, you can see more information right away. Of course, you can still see date and time, but now you can also see location, guest list, what calendar the event is on, and if you are attending. You can also email the guests from the event pop-out! Click MORE OPTIONS ...

Add 'Em Up: A New Strategy for Me

Image
As is often the case at this time of year, the winter weather is breaking up my lessons. I introduced stoichiometry, or what I call reaction math, on December 13 but some snow days and semester exams put it on the shelf almost immediately. Now that we are back to school, I needed a way to help students review what they began almost one month ago.  I am often inspired by the tweets and blogging of Sarah Carter . I haven't met Sarah, but I know she teaches math and chemistry in Oklahoma. I read her detailed blog posts where she generously shares many great ideas with great interest. Sarah has written about a favorite strategy called Add 'Em Up and her posts were the inspiration for this lesson. In Add 'Em Up, a sheet is created with four math problems. When the answers are added, they should equal a sum that is provided. If the answers do not equal the sum, students know they need to look for, and correct, their errors. With my teaching partner, I created an Add 'Em Up a...

Whose Game for Chemistry? Science Ninjas Valence

Image
Every since I read this post by the amazing Sara Vanderwerf , I have been kicking around the idea of a game table. Honestly, when I first read it, I thought that math teachers are so lucky that there are so many cool math games you could put at a play table. Then I read this post from A Mighty Girl blog. There is a game mentioned called Compounded that caught by eye. So I searched for it on amazon; the search lead to a lot of chemistry games. It turns out that chemistry teachers are also lucky that there are cool games for a play table. One I recently bought is called Science Ninjas Valence . Science Ninjas Valence is a card game that plays quickly. Each player gets six cards from the shuffled deck. The rest of the deck goes face down and the top card is turned up. Players look at the element cards in their hands and try to make compounds - acids, bases, salts, water, carbon dioxide, etc. When you can make one, you discard your cards and pick up the compound card that you made. Eac...

Happy Retirement, g(Math)! Welcome aboard, #EquatIO!

Image
image from texthelp.com Yesterday g(Math), a popular add-on to Google apps for inserting math, was officially retired. This means it can no longer be downloaded and added on, and it doesn't appear in my list of add-ons any more. If you loved using g(Math), you will find much of what you used in the Chrome extension EquatIO which was developed from g(Math) by John McGowan with support from TextHelp. If you have never used g(Math), or EquatIO, read on for some details. Install EquatIO from the Chrome store . If you're a teacher, apply for a free premium account after you install it . You must be signed in to Chrome to use the extension. This is one drawback for teachers who teach in many rooms with shared computers, but I don't think it's a deal breaker. Once you install it, you will find its icon at the top of your browser window, to the right of the address bar. The premium account of EquatIO, free for teachers (thanks, TextHelp! ), will allow you to add math to Google...

What Top Chef Taught Me About Teaching

Image
Did you see this tweet on New Year's Eve? I did, and just as my wheels started turning about how fun it could be, the tweet was quickly ratioed . The Math-Twitter-Blog-o-Sphere almost universally hated the idea. Math teacher Jamie Garner postulated that the idea could work and posted this good read to her blog. Other than Jamie, most comments read like Alice Keeler's opinions on homework . I don't watch a ton of TV, but a few reality shows have captured my interest over the years. I jumped on the American Idol bandwagon after season 1, but was with Project Runway right from the start. This summer the viral Mandy Harvey video got me hooked on America's Got Talent. My unlikeliest love is Top Chef. Who wants to watch a show where you see food being prepared but don't get to eat it? It turns out, I do! Here are my takeaways from my reality show viewing: You will have to step out of your comfort zone to create something spectacular. But it's important to edit. Don...
