Decide how students will construct their explanations (see options in step 2 of the directions). If students will use the worksheet, prepare one copy of 6.4 Explaining Functions that All Decomposers Share Worksheet for each student. If students will create a PowerPoint, check that computers or tablets are working and ready. If students will make a poster, get one blank poster for each pair or small group of students. Decide how you will have students present their explanations (see step 3 of the directions). Prepare a computer and a projector to display the PPT.
Use the 6.4 Grading the Explaining Functions that All Decomposers Share Worksheet to grade students’ explanations. Regardless of how students constructed their explanations, they should include similar information.
