Instructional Ideas

• Provide the class with a third measuring device and have them calculate the measurements of objects given the ratio of the new device to one already used
• Use inches and centimeters to measure objects and find the conversion factor

Classroom Considerations

• Requires two different sizes of stick-on notes of different colors
• One part of a larger Math at the Core: Ratios series
  

Pros

• The video is available in Spanish
• Provides questions to ask at specific times during the video
