Okay so at my preschool (3's class) we talk about patterns. We find patterns in our classroom, on our clothing and find pattern games in our manipulative center. After it is introduced we have a 'I can make a pattern' worksheet where the kids can make a pattern with colored shapes. What are your thoughts on this? I read more and more about the downside to worksheets, but I also feel like I need some concrete work from them to demonstrate progress and things to put in their portfolios at the end of the year.
