I found some information on task cards:
Task cards are pretty self-explanatory: they are cards which contain tasks, or activities for students to complete. Teachers usually create a deck of these task cards for students to practice skills. They are good worksheet alternatives, can be adapted in to games, easy to make and readily accessible since so many teachers make and share them.
Here are some resources about task cards, if you're thinking about utilizing them:
- Task-Cards.com, which gives a thorough explanation for various ways to use task cards, including for individual, small group and whole class activities. The site also provides details on several types of task cards and gives examples of each. There are also four sets of free task cards as a sample of the type of material sold on the site. Visit here for a one-stop shop for info on task cards!
- Talbott's Teaching Trove contains a few sets of free task cards, including working with antonyms and rounding numbers. My favorite are the "7-Up" cards, which encourage students to turn short, lifeless sentences into descriptive ones.
