I think I used weak index cards
I thought index cards were pretty uniform, but found that even our arch shape was pretty floppy with the ones I had, and as we worked with them, I realized they felt a little thinner than I'm used to. Kids had a good time beefing up the tape and found the shapes held up better when taped into groups, but we never wound up with a highly functional bridge. I also found that 10+ was probably too few cards for any kids. Luckily, they're cheap, so have lots of them! Kids had a fun time with the activity.
