I'm sure there's a worksheet out there for what I'm about to share, but I sure do love the fact that my kids didn't have to use it.
I recently introduced them to compound words. Actually, our weekly big book introduced them to compound words. After a few days of working with the book and the concept as a group, it was time to individually practice. Previous to the lesson, I wrote words on small post-its. Half of the words were compound words and the other half were not. As you'll see in the following pictures, the post-its found themselves stuck to foreheads. The kids made Yes/No T charts and traveled around to each other, writing down words. Compound words went under "Yes." The others, "No."
Of course, this activity could be modified to fit most any skill. It's so easy to prepare, requires no paper waste, and is loads better than a worksheet!
