Name Date Period Stained Glass Window Project Description Project Description: create a stained glass window using proportional and non-proportional linear equations. For each linear equation, identify the slope and y-intercept and then graph the equation. • • • • • • Supplies: construction paper, straight edge, glue stick, pencil, colored pencils and graph paper. Identify the slope and y-intercept for each equation. On your graph paper, lightly draw your coordinate plane. The axes should be in the center of the page but on the grid lines. Draw each line on your graph paper. Label each line with the line number. Use a straight edge and draw the lines to the edge of your graph paper. When you are finished, neatly color the sections to make a stained glass window design. Glue graph paper on the front of construction PROJECT DUE: paper and Stained Glass Window Project the of back Monday, 10/27 Periods: 1, 3, 5, 7 Worksheet and Rubric on the Tuesday, 10/28-Periods 2, 4, 6 construction paper. 1 Date Name Period Stained Glass Window Project Worksheet and Rubric Line 1 2 3 4 5 6 7 8 9 10 Equation Slope V-Intercept y= —21 x — 4 3 y= 2 x + 12 y = 12 1 y= 2 x + 4 y= 2— lx 4 1 y= — — x + 4 2 3 y= — — x + 12 2 y = —12 3 y= — — x — 12 2 3 y= 2 x — 12 Rubric: Category Slope Y-Intercept Lines Creativity Presentation Grade: Excellent (9-10) Correctly identifies all slopes of the lines. Correctly identifies all yintercepts of the lines. Correctly represents equations as a line and labels every line. Drawing, labeling and lines are neat and significant effort is shown. All lines are clearly drawn using a straight edge. Project is presented as instructed. (out of 50) Good (6-8) Most of the slope are identified correctly. Most of the y-intercepts are identified correctly. Represents some equations as a line and labels most lines. Project is neat and easy to read. Final product shows effort and time taken to complete the project. Some lines are clearly drawn and a straight edge was used. Project is presented as instructed. Poor (0-5) Some of the slopes are incorrect or missing. Some of the y-intercepts are incorrect or missing. Lines are not labeled. Project is not neat and easy to read. It does not show significant effort. Lines are not clearly draw or draw free hand. Some parts of the project are not included or are incorrect.
