Many #teaching techniques (e.g., Mazur’s Peer Instruction) suggest asking a (well-designed) #MultipleChoice question of the class and having them hold up #cards marked A/B/C/D.
… so you’d think someone would be manufacturing such cards. After several minutes of searching, pretty much all I can find are PDF templates to print out and cut apart with scissors.
Closest thing so far:

There has to be a way to do this more cheaply. Also, having each letter a different color would make it easier to read the room.
@peterdrake possibly dumb idea: label the answer candidates with colours instead of or in addition to letters and use an Uno deck, which would be enough for 25 students after removing the wild cards. Looks like they generally retail for about 6USD. There's a version called ColorADD in case some students are colourblind, but I think the shades are sufficiently different it shouldn't pose much of a barrier to accessibility if you just use a normal deck.
@khird Not a bad idea at all -- I was starting to consider that already.
The ColorADD version is neat, but appears to be currently unavailable. It looks like it just adds a symbol to each color. If a colorblind students gets a blue 1, a red 2, a green 3, and a yellow 4, that could work just as well.
@peterdrake at my uni, we all had to buy these clickers that registered our responses, then the instructor would display them on the board
@2ck Yeah, that can also be done with web services like PollEverywhere.
The clickers are needlessly expensive and even the website is another layer of technology I'm hoping to avoid.
After getting responses from several sources, I’m leaning toward just grabbing a box of colored cards like the one below and having the students write A/B/C/D on them with sharpies (which also dodges the colorblindness issue).
