Scale Drawings

Are you searching for a purpose for geometric constructions? Use an engaging approach to explore dilations. Scholars create dilations using a construction method of their choice. As they build their constructed dilation, they strengthen their understanding of scale and apply it to real scenarios.

Instructional Ideas

  • Have learners use graph paper when creating scale drawings to compare lengths of sides using distance formula and/or Pythagorean Theorem to verify the scale
  • Allow pupils to use geometry software such as Geogebra to create scale drawings
  • The first lesson in a 36-part series
Classroom Considerations

  • Pupils need construction tools to complete the drawings
  • Activity may require a review of scale and constructions depending on the background knowledge of your students
Pros

  • Uses good examples to stress the idea that dilations must preserve angle measurements
  • Contains a complete lesson from opening exercise and independent practice problems to the included exit ticket
Cons

  • None
