A very basic quiz and key for US Capitals.
I have students study for a few minutes, give the quiz for five minutes total, and have students correct their own. The whole cycle usually takes about 20 minutes but can be as shorts as 10 minutes and as long as 30, depending on needs.
Once a student reaches all 50 correct from their desk, they join me at a back table to take the move-on quiz where spelling also counts.
Students progress from US States to US Capitals to US Presidents and finally, US Vice Presidents.
