These newsletters were created a few years ago as a way to inform my parents about what we were learning in math as well as some "real-life" suggestions of how to practice the skill at home. These skills are no longer a part of the first grade standards. I will be using these newsletters as enrichment for my students.
You can find newsletters, exit slips and skill cards for the first grade common core standards at my TPT: http://www.teacherspayteachers.com/Store/Danielle-Lasota
