## Students Explaining why 7/8 = 87.5% Excellent Student Talk

Hear 6th grade students explain multiple strategies for finding an equivalent percentage to the fraction, 7/8. The teacher uses effective questioning to elicit responses from students.

__Congruence and Similarity Using Rigid and Non-Rigid Motions__

This is an excerpt from an

__EXCELLENT website__that has numerous lessons for teaching the mathematical standards (content and practice). For the shortened__PowerPoint Presentation__that shows what it looks like to teach congruence and similarity in the way the CCSS/KCAS intened.

To reinforce and honor the language of the standards, we have directly correlated the mathematical practice standards to excerpts of mathematics lessons. Just as with content standards, not every lesson reflects all elements of the individual standards for mathematical practice. By representing examples from different classrooms for each standard, we also want to emphasize how many different ways teachers may enact these standards for mathematical practice in their classrooms, with their particular learners. While there is no one "right way," there are multiple examples of successful strategies to launch and sustain these practices. Click the individual standards below to see instances of the practice standards in classroom lessons. Although the practices are presented here individually, it's important to keep in mind that the practices can, and should, be evident together in a lesson. See the

Explore materials and tasks you can use immediately with your students. Inside Mathematics has aligned our tasks and assessment resources with the Common Core State Standards for Mathematical Content. Note that you can make use of these standards through searching by grade level as well as by progression, so we have provided two routes through these tasks and other resources
