standard_description: Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.
problem_activity: Your school's office manager surveyed the entire sixth grade to find out what transportation students use to get to school. She determined that the ratio of students who took the bus to students who walked to school to students who got a ride was 5:3:2.
If 27 students walked to school, how many students are in the sixth grade? Draw a tape diagram and use it to show your answer.
