Card sorts are one of my favorite tried-and-true ways to formatively assess my students. I use them all the time!
1. You can use them at the beginning of a lesson to check for prior knowledge
2. You can use them in the middle of a lesson as a checkpoint for the lesson
3. You can use them as a form of exit ticket
4. You can use them the day before a quiz for students to self-assess
I've found they are great for my ESL students and tactile learners. Once they are sorted, have your kids read them out loud to get your ESL kids talking and practicing vocabulary.
Are you sold yet? It's super easy to make your own! For example, suppose you are learning mitosis. All you have to do is look up a picture of the phases of mitosis on the internet, and print off multiple copies (I have 16 lab tables in my room, so I usually make 16 sets and have students work in pairs). Next, cut them up, paperclip together, and voila! (Bonus: if you have a laminator or your school library can laminate for you, it makes them more durable from year to year).
Since I have so many sets, I needed a way to keep them organized that worked for me. The best (and cheapest) way I've found to organize my card sorts, task cards, and review puzzles is in small manila envelopes. I write the topic on the front and they are placed in order that I use them (quarter 1 through 4) in a filing cabinet.
