This lesson unit is intended to help teachers assess how well students are able to visualize two-dimensional cross-sections of representations of three-dimensional objects. In particular, the lesson will help you identify and help students who have difficulties recognizing and drawing two-dimensional cross-sections at different points along a plane of a representation of a three-dimensional object.

This Demonstration illustrates the concept of rotating a 2D polygon. The rotation matrix is displayed for the current angle. The default polygon is a square that you can modify.

In this four part series, we visit the classrooms of two partner teachers who plan all their lessons together but have totally different styles inside the classroom. See the same lesson unfold in each class, the class structures used by each teacher, and the group work formats used by each.

This lesson unit is intended to help teachers assess how well students are able to: work with concepts of congruency and similarity, including identifying corresponding sides and corresponding angles within and between triangles; Identify and understand the significance of a counter-example; Prove, and evaluate proofs in a geometric context.

This lesson unit is intended to help you assess how well students are able to use geometric properties to solve problems. In particular, it will support you in identifying and helping students who have the following difficulties: Solving problems relating to using the measures of the interior angles of polygons; and solving problems relating to using the measures of the exterior angles of polygons.

This lesson unit is intended to help teachers assess how well students are able to create and solve linear equations. In particular, the lesson will help you identify and help students who have the following difficulties: solving equations with one variable and solving linear equations in more than one way.

This document is based on an analysis that determined the sub-skills students need to achieve in each of the Foundational Skills (K–5) in the Common Core State Standards (CCSS). It contains five sections, each targeting one grade level in: Print Concepts, Phonological Awareness, Phonics and Word Recognition, and Fluency. It also includes instructional examples aligned to the sub-skills, giving teachers samples of activity types that facilitate acquisition of the sub-skills. Each chart includes up to three grade levels to inform instruction for students who are either struggling and need extra support or intervention, or for students performing above grade-level expectations and require enrichment, to allow a teacher to see which skills should have been mastered in the previous year and what students are preparing for in the upcoming years.

Overview of how the Pennsylvania Common Core Standards for Mathematics are driving changes in classrooms and schools, and where resources can be found to support the implementation of those changes.

This is a complete, full-year Algebra 1 course with tons of interactivity included in every lesson. Some lessons include videos, and all include interactives and newly added inline questions. Inline questions offer instant, per-answer feedback to help you learn by knowing why your answers are correct or incorrect. Every lesson also has specifically chosen 'Related Modalities' that teach the same concept in different ways. Related Modalities may be additional videos, interactives, or study guides (often written by students themselves). You can choose to use the resources directly embedded within the Algebra 1 FlexBook® 2.0 lessons, or learn Algebra your way by using the Related Modalities that are most effective for you!

This lesson unit is intended to help teahcers assess how well students solve problems involving measurement, and in particular, to identify and help students who have the following difficulties; computing measurements using formulas; decomposing compound shapes into simpler ones; using right triangles and their properties to solve real-world problems.

This lesson unit is intended to help teachers assess how well students are able to classify solutions to a pair of linear equations by considering their graphical representations. In particular, this unit aims to help teachers identify and assist students who have difficulties in: using substitution to complete a table of values for a linear equation; identifying a linear equation from a given table of values; and graphing and solving linear equations.

Achieve and the U.S. Education Delivery Institute have developed a practical Common Core Implementation Workbook for all states in the Partnership for Assessment of Readiness for College and Careers (PARCC).

The workbook uses a proven performance management methodology known as “delivery” to lay out clear action steps for states and districts. It provides relevant information, case stories of good practice, key questions and hands-on exercises for leadership teams to complete together. Regardless of your state's timeline, the workbook offers state and district leaders the means to plan for the CCSS and then drive successful implementation.

This 14-minute video for educators introduces working with Common Core standards for English and math. How will teaching to the Common Core affect teaching practice in the classroom? Teachers and Principals discuss the opportunities Common Core offers to their students and to their own focus and teaching practice.

This 14-minute video lesson for high school educators introduces working with Common Core Standards. How will teaching to the Common Core affect teaching practice in the classroom? How can teachers help students learn to apply math and think about problem solving outside the math classroom? What does an emphasis on “depth” look like in practice? How can teachers make adapting to the Common Core a reflection point in their own practice? Teachers and principals discuss the opportunities Common Core offers for their students and for their own focus and teaching practice.

This 14-minute video lesson for middle school educators introduces working with Common Core State Standards. How will teaching to the Common Core affect teaching practice in the classroom? See how Common Core has affected teaching and learning at two pilot schools where they have already been adapted. Does the dialogue in the pilot school math classroom sound like your classroom now? What has the culture shift been like for teachers and students? How will the shift in emphasis on non-fiction reading and expository and persuasive writing benefit students? Teachers and principals discuss the opportunities Common Core offers for their students and for their own focus and teaching practice.
