In the past couple of weeks, we have been reading books during Reading Workshop mini-lessons and noticing the signal words that "tell us something is going to change in the story".
After their experience with this in reading, we created an anchor chart for signal words to use in their writing.
We related signal words to signs on the road because they tell us to notice something that is changing just like signs tell us to notice or do something differently.
Here is the book that we read before making the anchor chart:
It's called City Signs by Zoran Milich.
Now that we have the anchor chart, my kindergartners are coming up to me in the middle of read to self time to tell me that they found a signal word in the book and they can't wait to use it when they write. :)
