Unit 2

Unit 1. Collection Search - Gooru. Collection Search - Gooru. A.CED Resources. Pythagorean Theorem. Use this activity to help your students discover the Pythagorean theorem. Pythagorean theorem work is often skill and drill work with contrived right triangle problems. In this activity students work with a visual representation of the Pythagorean theorem in order to gain a conceptual understanding of the theorem.

Students can engage in several of the standards of practice including: (3) construct viable arguments and critique the reasoning of others, (4) model with mathematics, (7) look for and make use of structure, and (8) look for and express regularity in repeated reasoning. Students can also engage in practice 5: use appropriate tools strategically by using a program such as Geometers Sketchpad or Geogebra to investigate the theorem. Here is a GeogebraTube app on the Pythagorean Theorem Simply click on and drag points A, B or C to manipulate the model. pythagorean-investigation.pdf For members we have an editable Word doc and solutions. 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. Encourage a student to come to the front of the room and draw a line with positive 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. Shade in the slope triangles with students as shown below. 1. 3d-Pythagoras-Treasure-Hunt. Joulies.
