Common Core Classroom Resources

Share My Lesson
Share My Lesson is a place where educators can come together to create and share their very best teaching resources. Developed by teachers, for teachers, this free platform gives access to high-quality teaching resources and provides an online community where teachers can collaborate with, encourage and inspire one another. Share My Lesson’s Common Core Information Center is dedicated to all aspects of the Common Core from identifying aligned resources to illustrating instructional strategies to providing the latest news about implementation. Share My Lesson was developed by the American Federation of Teachers and TES Connect, the largest network of teachers in the world. Everything can be accessed for free at Registration is required, so join now!

AFT Sample Parent Letters

The AFT has prepared sample parent letters on selected mathematics topics for grades K-8. The aim is to help parents better understand some of the new language in the Common Core State Standards (CCSS) and strategies they may see their children use on their journey to achieving the understanding and skills required by CCSS. New letters will be added throughout the year. You can personalize these letters with your school name, logo and signature and send to parents or post on your school’s website. Each link below includes English and Spanish versions of the selected letter.

Colorín Colorado
The resource section on Colorín Colorado, a project of WETA and supported by AFT, offers information to educators and parents about what the new standards will mean for English language Learners (ELLs). The Common Core State Standards and English Language Learners webpage provides a compilation of CCSS materials focused on ELLs; these resources continue to fill a void because most standards-related material lacks information specific to ELLs. The materials include video interviews with experts and practitioners, informational guides, a blog, ideas for lesson plans, and more. The Colorín Colorado team regularly engages with educators, researchers and policymakers regarding news from the field.

Illustrative Mathematics Project
Illustrative Mathematics is an initiative of the Institute for Mathematics & Education at the University of Arizona. The Illustrative Mathematics website contains hundreds of free CCSS-aligned sample problems, videos and other resources, organized by grade, standard and domain.

Implementing the Common Core State Standards: A Primer on “Close Reading of Text”
To assist teachers in understanding and employing the Common Core instructional emphasis on close reading in the classroom, this primer, from the Aspen Institute, addresses the following key questions: What is close reading of text, and what are its essential attributes? How, and for what purposes, should teachers employ this strategy? What is the role of background knowledge in the development of reading comprehension, and when should teachers activate and/or provide background knowledge? What should teachers and district leaders consider about close reading as they prepare to implement it in practice?

Mathematics Assessment Project
The Mathematics Assessment Project (MAP) aims to bring to life the Common Core State Standards in a way that will help teachers and their students turn their aspirations for achieving them into classroom realities. MAP is a collaboration between the University of California, Berkeley, and the Shell Centre team at the University of Nottingham, with support from the Bill & Melinda Gates Foundation. The team works with the Silicon Valley Mathematics Initiative and school systems across the U.S. and U.K. to develop improved assessment. The materials from this project will exemplify the CCSS-M in explicit, down-to-earth performance terms.

Progressions for the Common Core Math Standards
The Common Core State Standards in mathematics were built on progressions: narrative documents describing the progression of a topic across a number of grade levels, informed both by research on children’s cognitive development and by the logical structure of mathematics. The progressions can explain why standards are sequenced the way they are, point out cognitive difficulties and pedagogical solutions, and give more detail on particularly knotty areas of the mathematics.

Questions for Math Class: Elementary
This AFT Common Core brochure offers helpful questions as teachers implement the Common Core State Standards for Mathematics.

Student Achievement Partners
Student Achievement Partners offers a website full of free content designed to help educators understand and implement the Common Core State Standards. It includes practical tools designed to help students and teachers see their hard work deliver results. The website,, was created in the spirit of collaboration—the content is assembled by and for educators and is freely available to everyone to use, modify and share.

Teaching Channel
The Teaching Channel is a video showcase of innovative and effective teaching practices in America’s public schools. There are nearly 800 videos to choose from, many of which allow teachers to see the Common Core standards in action in real-life classrooms. Supplemental resources accompany each video, and teachers can write time-stamped notes on each video to share with their colleagues. The Teaching Channel also offers a live Q&A exchange so that teachers can ask any question about the Common Core and get an email alert when the answer is posted online.
