Anchor charts are great for leaving up in your classroom all year long to give kids a reminder of the strategy or skill at hand.
In this case, The Author's Purpose is discussed.
On the poster (as you can see in the thumbnail above), includes a brief overview, an example, and key words that may be heard when discussing this reading strategy.
Couple of Notes:
*Also included is one page of sheets that you can give to students to have them write their own examples. I hand this poster in the center of a bulletin board and then hang the kids' examples around the edge of the poster, making this an interactive bulletin board where students get a lot of practice throughout the year.
*I would suggest having this poster blown up to either a 18x24 inch or 24x36 inch size. www.shortrunposters.com is very reasonable, with the 18x24 inch poster costing $2.97 plus tax.
*I also have an entire bundle of all of my anchor charts included in my store. Great for beginning of the year and all year long!
