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 is a task where it would be appropriate for students to use technology such as a graphing calculator or GeoGebra, making it a good candidate for students to engage in Standard for Mathematical Practice 5 Use appropriate tools strategically.

Through funding provided by Georgia’s Race to the Top initiative and in partnership with the Georgia Department of Education, new self-paced common core professional development course Mathematics teachers.

The Georgia Department of Education has developed two flexible, ready-to-use courses intended to support Georgia educators in the understanding and effective implementation of the CCGPS.

The courses may be used by individual educators, professional learning communities, or by districts or schools. The time required for the courses may be customized for a variety of applications by expanding the amount of time spent on the activities and in discussion.

Each course contains hands-on activities, related readings and research, recommended topics for discussion, web and video resources, and self-assessments.

The content of the courses was developed under a grant from the U. S. Department of Education. However, the content does not necessarily represent the policy of the U. S. Department of Education, and endorsement by the Federal Government should not be assumed.

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 introduces the key features and differences of the new Common Core State standards for math. It looks at the purpose of the standards for mathematical practice and how they should be integrated with content. It looks at how teaching fewer topics in each grade will change educator planning. And it discusses how the new standards can help close the achievement gap.

This task provides an opportunity to work on the Standard for Mathematical Practice 3 Construct Viable Arguments and Critique the Reasoning of Others.

With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. In his talk, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think. (Filmed at TEDxNYED.)

This module fosters a careful understanding of the Common Core State Standards math shifts. Participants take a deep dive into the major work of grades K-8, build a deeper understanding of the coherence of the Standards, and work through sample problems that reflect the "rigor" expected by the Standards.

This lesson unit is intended to help teachers assess how well students are able to: Select appropriate mathematical methods to use for an unstructured problem; interpret a problem situation, identifying constraints and variables, and specify assumptions; work with 2- and 3-dimensional shapes to solve a problem involving capacity and surface area; and communicate their reasoning clearly.

This lesson unit is intended to help teachers assess how well students understand the notion of correlation. In particular this unit aims to identify and help students who have difficulty in: understanding correlation as the degree of fit between two variables; making a mathematical model of a situation; testing and improving the model; communicating their reasoning clearly; and evaluating alternative models of the situation.

This lesson unit is intended to help assess how well students are able to interpret and use scale drawings to plan a garden layout. This involves using proportional reasoning and metric units.

This lesson unit is intended to help you assess how well students are able to: solve simple problems involving ratio and direct proportion; choose an appropriate sampling method; and collect discrete data and record them using a frequency table.

This lesson unit is intended to help you assess how well students are able to: Model a situation; make sensible, realistic assumptions and estimates; and use assumptions and estimates to create a chain of reasoning, in order to solve a practical problem.
