News & Updates Rise-Run Triangles To start the lesson, ask students what they already know about slope. They may know terms such as rate of change and rise over run. Often, students have recollection of these terms but don't remember or understand what they mean or how they relate to slope. Ask students what it means to have positive or negative slope. A line with positive slope is pointing upward as you look to the right. Sketch these two lines with positive slope for students to see. Ask students to tell you all they can about the two graphs. Now, draw a third line that has the same slope as the first line, but a different y-intercept. Students should eventually recognize that the third line has the same slope as the first line. Use the activity sheet for practice and enforcement. The activity sheet guides students through a process for finding the slope of a given line. Distribute the activity sheets and make sure each student has 1 or 2 colored pencils. Shade in the slope triangles with students as shown below. 1.
grade7commoncoremath - home 50 Important Links for Common Core Educators Educators across the nation are working hard this summer to begin developing updated curricula that will fit into the new Common Core State Standards, which will be fully applied in 45 U.S. states (Texas, Alaska, Nebraska, Virginia, and Minnesota have opted out of statewide participation) by 2015. Yet despite the hubbub about the new standards, which were created as a means of better equipping students with the knowledge they need to be competitive in the modern world, many teachers still have a lot of unanswered questions about what Common Core will mean for them, their students, and their schools. Luckily, the Internet abounds with helpful resources that can explain the intricacies of Common Core, offer resources for curriculum development, and even let teachers keep up with the latest news on the subject. We’ve collected just a few of those great resources here, which are essential reads for any K-12 educator in a Common Core-adopting state. Groups and Organizations Useful Resources

Tools Bill, My wife and I are currently assisting the Amphitheater School District with the training of their teachers from grade K to 6 on the Common Core Standards. We would love to have links in our PowerPoint presentations and PDF files (both of which we give to the teachers attending our classes) that went directly to a portion of the text or an illustration that we would like to provide as part of our lesson. For example, teachers have a hard time understanding the division of a fraction by a fraction. The problem is that I see no way to link to this illustration directly, or any text with the illustrations. Robert Springer Games Summary Games of chance hold an honored place in probability theory, because of their conceptual clarity and because of their fundamental influence on the early development of the subject. In this chapter, we explore some of the most common and basic games of chance. Roulette, craps, and Keno are casino games. The Monty Hall problem is based on a TV game show, and has become famous because of the controversy that it generated.
