Ruler and Protractor

Lesson #12202
12202

The Ruler and Protractor are to scale for classroom use.



These measurement tools are quick and easy to make and can be used to measure angles and lines of many die-cut shapes.

Students can use the Ruler and Protractor to analyze data and solve problems in the classroom. They can also draw images to scale applying these tools.

The teacher will die-cut the materials for student use prior to the lesson.

  1. Die-cut two Rulers from cardstock or construction paper. Adhere the two Rulers together for a more durable Ruler.
  2. Trace and number the inch lines with a black permanent marker. Trace the 1/2" lines with a red marker (Figure A).
  3. Die-cut the Protractor from a clear plastic transparency sheet. 
  4. Use a red permanent marker to indicate the inches along the bottom of the Protractor.
  5. Use a black permanent marker to mark every 15 degrees to indicate the angles (Figure B).
  6. The clear Protractor can be placed over a shape to measure the angles and sides.
  7. Students can use the Ruler and Protractor for solving many math problems (Main Photo).
