### Make Math Flashcards on Canva

Canva is my go-to recommendation whenever someone asks me for help with anything requiring a bit of an eye for design. So on Wednesday when a reader asked me for a tool to create printable flashcards Canva was my recommendation. There are more than 300 flashcard templates in Canva's design gallery. In that gallery you'll find templates for making flashcards for math, spelling, geography, and more. And all of the templates can be modified to fit your needs.

In this short video I demonstrate how to use Canva to create printable math flashcards. While watching the video pay attention to my trick for making all of the cutting lines exactly the same.

Applications for Education
There is still a time and place for offline flashcards. The reader who emailed me this week wanted to make flashcards that her students could use at home with their parents in a screen-free environment. Canva provides a good way to make those flashcards to distribute to students and parents. Of course, students can also use Canva to create their own printable flashcards.

### Wind Chill and Our Perception of Cold

As I mentioned earlier this week, we've had a couple of exceptionally cold days here in Maine this week. One town near me recorded a wind chill of -36F on Tuesday. This weekend is supposed to be just as cold.  I've gone ice fishing in similar conditions without moaning about it (at least that's how I remember it). The cold got me wondering, "am I being a wimp about the cold or has my perception of cold changed?" At that line of thinking brought me back to an older Minute Earth video about perceptions of extreme weather.

The psychology of extreme weather
Is the weather really "extreme" or is that just our impression of it? The following Minute Earth video takes on the topic of how extreme weather affects our thinking about weather patterns in general. I found the video to be interesting from a psychology perspective. The video is embedded below.

How wind chill is calculated
As I mentioned above, the wind chill was -36F earlier this week in a town near mine. Wind chill or not, that's cold! The following video explains how wind chill is calculated. The video comes from Presh Talwalkar.
